The limited infrastructure puts the US at a disadvantage as global demand for lithium continues to grow
could establish a sovereign wealth fund to invest in domestic miners focused on critical minerals extraction and processing
The JV is expected to be finalized in the second half of 2025
The agency ended protections on federal land in Nevada and New Mexico partially to boost production of critical minerals
The German-Canadian company Rock Tech Lithium has received final approval from Brandenburg's state government for its lithium hydroxide converter currently under construction in Guben
There is no mention of whether subsidies from state funds will also be provided
Rock Tech Lithium recently received a funding cancellation from the federal government
The approval process for the plant has been officially completed with the handover of the approval notice from Brandenburg’s Environment Minister Axel Vogel and Economics Minister Jörg Steinbach
Rock Tech CEO Dirk Harbecke and Guben’s mayor Fred Mahro received the decision on Friday
The state government does not provide any information on subsidies in its announcement
The question of state funding arose in particular after it became known in May that Rock Tech would unexpectedly not receive any money from the federal funding pot created in 2023 to establish a battery cell ecosystem in Germany
The company then announced that it wanted to rely on other support to complete its lithium converter in Guben – in particular from the state of Brandenburg
Rock Tech is therefore an upstream link in the battery cell supply chain
it is actually the target group of the aforementioned federal subsidy programme
At the presentation of the funding programme last year
German Economics Minister Robert Habeck said that investments in the battery value chain would contribute to Europe’s strategic sovereignty
“It is disappointing that we are now not receiving the funds from the TCTF programme,” CEO Harbecke was quoted as saying in the German newspaper Handelsblatt in May
we are in very constructive dialogue with the Brandenburg state government
We assume that the state of Brandenburg will be able to mobilise sufficient regional funding to realise the project.” The local community of Guben reportedly also has a “great interest” in the project being completed
In the current communication on the approval
It merely states that around 160 jobs are to be created in Guben and recapitulates the construction process
Rock Tech Lithium announced the construction of its plant in Guben with advance authorisation at some risk: “Rock Tech has made use of the legal option of allowing an early start to the project
This made it possible to prepare the construction site even before the final authorisation was granted
The city council of Guben is closely monitoring the project,” the company explains
The Brandenburg State Environmental Agency has now given the green light ‘in an efficient immission control procedure with public participation’
The authorisation procedure took a total of two years
German Environment Minister Axel Vogel commented: “With the final approval for Rock Tech
Brandenburg can expand its leading role in the production of batteries for the expansion of e-mobility and electricity storage
(…) We are thus proving once again that Brandenburg is an attractive location for the transformation to a climate-neutral economy.”
“This is an exciting day for Rock Tech,” added Rock Tech CEO Dirk Harbecke
“Not only have we received the full permits to operate our Converter in Germany
but also are we the first company in Europe to permit a full-scale Lithium Refinery – without any appeals to the project
This is testament to the great work of our team
I also would like to thank the Brandenburg authorities for their support and diligence.”

Rock Tech Lithium and Arcore AG will merge to establish a fully integrated lithium supply chain from mine to battery-grade products
Rock Tech Lithium is aiming to produce lithium hydroxide for electric vehicles batteries in signing an agreement with Arcore
The merger will form a European joint venture
The core assets will include Rock Tech’s fully permitted lithium converter in Guben
and Arcore’s lithium-boron-magnesium mining project in Lopare
Rock Tech will contribute 75% of NewCo’s registered share capital and Arcore will hold shares representing 25% of the share capital
Arcore’s mineral deposit has the potential to become one of the largest lithium mines in Europe with estimated 600,00t of lithium carbonate equivalent
The Guben lithium converter is designed to produce battery-grade LHM for up to 500,000 electric vehicles per year
It is envisioned that the Lopare project will deliver lithium sulphate feedstock (produced at site) to the Guben converter from 2030 onwards
in addition to the already secured spodumene supply from contracted partners
The centrepiece of Rock Tech’s European activities is its planned lithium-hydroxide monohydrate (LHM) converter in the Brandenburg battery cluster
‘Strong European supply chains are essential to secure the region's strategic autonomy
promote industrial competitiveness and enable the transformation to a climate-neutral economy
'Europe is currently heavily dependent on imports of critical raw materials such as lithium
This is an important step for Rock Tech to become the European leader in battery raw materials supply.’

Rock Tech Lithium (TSXV: RCK; OTCQX: RCKTF) is partnering with Schwenk – a leading German cement manufacturer – to use lithium production by-products from Rock Tech's Guben converter for use in Schwenk's cement manufacturing
beginning with its proposed lithium-hydroxide converter in Guben
The parties believe the partnership will have significant environmental and economic benefits by reducing carbon emissions and creating a new revenue stream
"This partnership is a testament to our commitment to sustainability and formation of a circular economy
we enhance our profitability and support the cement industry's decarbonization efforts."
member of the management board for Schwenk Germany
"Ensuring the future supply of sufficient quantities of high-quality cement grinding materials is of great strategic importance for Schwenk
The leached spodumene concentrate produced during the operation of the planned converter in Guben represents an interesting and regionally available source of secondary raw materials.”
The primary objective of the partnership is to develop industrial applications for residues generated from Rock Tech's lithium-hydroxide production
The Institute of Technologies and Economics of Lithium (ITEL) conducted early studies and determined the leach residues had potential as supplementary cementitious materials (SCM) for use in cement manufacturing
New Revenue Stream and Improved Economics: Rock Tech will sell its by-products to Schwenk
thereby creating an additional income stream
The parties have agreed on key commercial terms
Lower Carbon Emissions: Using the leach residues as SCMs in cement production significantly reduces CO₂ emissions for Schwenk and reduces dependency on other SCMs from coal-based-energy production
which will be less widely available in the future
Cost Savings: Avoiding leach residue transportation and disposal lowers Rock Tech's annual operational expenditures by around 7% and reduces the Guben converter environmental impact
Schwenk plans to invest into state-of-the-art facilities for drying
and storing leach residues from lithium production
The company will invest upon successful ramp-up of Rock Techs' Guben converter
The agreement outlines that Schwenk eventually will offtake leach residues from Rock Tech's Guben converter
company workers will prioritize flexibility
including the option of temporarily utilizing residues in the high-temperature cement processes
To facilitate the widespread adoption of this innovation
both parties will jointly pursue critical certifications
including REACH compliance and approvals from the German Institute for Construction Technology (DIBt)
The certification process is expected to take up to 1.5 years
both parties agree to exclusive cooperation for the duration of the agreement
The second Converter is planned to be built in Red Rock
Rock Tech Lithium plans to source raw material from its own Georgia Lake spodumene project in the Thunder Bay mining district
Rock Tech's goal is to create a closed-loop lithium production system.
Schwenk Zement is one of Germany's leading cement manufacturers and a known force in the construction materials industry

Introduction: Fuqi Guben Gao (FQGBG) is a botanical drug formulation composed of FuZi (FZ; Aconitum carmichaelii Debeaux [Ranunculaceae; Aconiti radix cocta])
and Cinnamon (Neolitsea cassia (L.) Kosterm
It has been used to clinically treat nocturia caused by kidney-yang deficiency syndrome (KYDS) for over 30 years and warms kidney yang
the pharmacological mechanism and the safety of FQGBG in humans require further exploration and evaluation
Methods: We investigated the efficacy of FQGBG in reducing urination and improving immune organ damage in two kinds of KYDS model rats (hydrocortisone-induced model and natural aging model)
and evaluated the safety of different oral FQGBG doses through pharmacokinetic (PK) parameters
and occurrence of adverse reactions in healthy Chinese participants in a randomized
Forty-two participants were allocated to six cohorts with FQGBG doses of 12.5
The PKs of FQGBG in plasma were determined using a fully validated LC-MS/MS method
Results: FQGBG significantly and rapidly improved the symptoms of increased urination in both two KYDS model rats and significantly resisted the adrenal atrophy in hydrocortisone-induced KYDS model rats
No apparent increase in adverse events was observed with dose escalation
Major adverse drug reactions included toothache
The PK results showed a higher exposure level of benzoylhypaconine (BHA) than benzoylmesaconine (BMA) and a shorter half-life of BMA than BHA
and hypaconitine were below the lower quantitative limit
Drug-induced metabolite markers primarily included lysophosphatidylcholines
and arginine metabolites; no safety-related metabolite changes were observed
Conclusion: Under the investigated dosing regimen
The efficacy mechanism of FQGBG in treating nocturia caused by KYDS may be related to the improvement of the hypothalamus-pituitary-adrenal axis function and increased energy metabolism
Clinical Trial Registration: https://www.chictr.org.cn/showproj.html?proj=26934
Preclinical pharmacological study results indicated that FQGBG substantially improved polyuria in four kinds of KYDS rat models
the effect observed was faster than positive controls (Gui-fu-di-huang-wan and You-gui-wan)
FQGBG can significantly counteract hydrocortisone-induced adrenal atrophy in rats with KYDS
increase their adrenocorticotropic hormone response
and significantly prolong the ice-water swimming time of mice with KYDS
FQGBG was developed by the Yunnan Institute of Materia Medica and Yunnan Baiyao Group Co.
and has been approved for clinical trials by the National Medical Products Administration (NMPA
2016L10230) as an investigational agent in Chinese medicine
Chemical structural formulas of the major diterpene alkaloids in FQGBG
we investigated the efficacy of FQGBG in improving the symptoms of kidney-yang deficiency in two types of KYDS model rats
and evaluated the safety of different oral doses of FQGBG through PK parameters
metabonomics and occurrence of adverse reactions in healthy Chinese participants
This study attempts to implement an evaluation model that combines drug exposure
and will provide evidence for the mechanism of exploration of the safety and efficacy of FQGBG in humans
FQGBG comprises FuZi (FZ Aconitum carmichaelii Debeaux [Ranunculaceae; Aconiti radix cocta]), Wolfberry (Lycium barbarum L. [Solanaceae; Lycii fructus]), and Cinnamon (Neolitsea cassia (L.) Kosterm. [Lauraceae; Cinnamomi cortex]). The plants’ names were verified at http://mpns.kew.org/mpns-portal/
All pharmaceutical raw materials were processed and quality tested according to the Pharmacopoeia of China (2015)
The processing method for FZ involves taking the daughter roots of the Ranunculaceae family plant Aconitum carmichaelii Debeaux
immersing them in a bile salts aqueous solution for several days
and then boiling them with the soaking solution until they are thoroughly penetrated
and longitudinally sliced into pieces about 0.5 cm thick
The slices are further soaked and rinsed with water
and then a coloring liquid is applied to dye the slices a deep tea color
they are steamed until an oily surface and luster appear
Quality control tests for FZ include appearance
thin-layer chromatography (TLC) identification
The processing method for Wolfberry entails harvesting the red fruit of Lycium barbarum L
The fruit is left to air until the skin wrinkles
Quality control for Wolfberry includes assessment of shape
Cinnamon is processed by peeling the bark of Neolitsea cassia (L.) Kosterm
Quality control tests for Cinnamon include appearance
Y180301) all met the quality standards of the Pharmacopoeia of China (2015)
The preparation method for FQGBG is as follows: FZ were decocted twice with water
first under a pressure of 0.10 MPa for 2 h and then at atmospheric pressure for 1 h
The filtrates from both decoctions were combined and concentrated to a relative density of 1.1 at 60°C for use
Cinnamon were ground and subjected to steam distillation for 4 h
The distilled Cinnamon oil was then complexed with β-cyclodextrin at 40°C for 2 h and set aside
The leftover Cinnamon residue and Wolfberry were extracted with hot water at 85°C twice
This extract was also concentrated to a relative density of 1.1 at 60°C for later use
the two concentrated extracts were blended with honey
The relative density was adjusted to between 1.3 and 1.4 at 25°C to yield the final product
which includes three types of identification fingerprinting (TLC
as well as methods for quantification of six aconitine alkaloids (AC

The clinical study was conducted at Xiyuan Hospital
and all clinical procedures were performed in compliance with the International Conference on Harmonization - Good Clinical Practice and the Declaration of Helsinki
Forty-two healthy Chinese volunteers aged between 18 and 50 years with body mass indices (BMI) between 19.0 and 25.0 kg/m2 and normal physical examinations, imagological electrocardiogram examinations, and clinical laboratory tests were enrolled in the trial. The exclusion criteria are provided in Supplementary Material S1
All participants provided written informed consent before the start of the study
This phase I, randomized, double-blind, placebo-controlled, single ascending dose clinical trial involved six cohorts with oral doses of 12.5 g (±1 g), 25 g (±1.5 g), 50 g (±2.5 g), 75 g (±3 g), 100 g (±4.5 g), and 125 g (±7 g) FQGBG. As shown in Figure 2
the participants (n = 42) were allocated to the cohorts (eight participants per group
including six with FQGBG and two with placebo
except for the first cohort (only two participants were treated with FQGBG)
Participants were administered FQGBG or placebo at the respective dose levels with 240 mL water under fasting conditions (overnight fasting for ≥12 h)
The procedures of administration were: 10 mL of water was poured into the FQGBG bottle
The mixture was then poured into a paper cup
after which the above operation was repeated twice
The remaining water was poured into the paper cup and stirred evenly
Sampling for PKs was designed based on PK results in our previous study and collected at different time points before and after the administration of FQGBG: at 0
The preliminary study results indicated that the blood concentration of the three monoester-type alkaloids was reduced to 1/10th of the maximum concentration (Cmax) at 60–120 h; thus
120 h after dosing was chosen as the last PK sampling time point
blood samples were collected before and after 30 min and 24 h
and urine specimens were collected before and after 24 and 48 h to compare the differences in endogenous metabolites
Blood and urine samples were centrifuged at 1,500 ×g for 10 min at 4°C and the supernatant of the urine was added to preservatives
All sample supernatants were collected and stored at −80°C
Plasma (100 μL) samples spiked with 20 μL of IS were mixed evenly on a shaker
500 μL ACN containing 0.1% formic acid was added to the sample
Protein precipitation was performed by vortexing the mixture for 10 min and then centrifuging at 4,000 rpm for 10 min at 4°C
Supernatant (150 μL) was added to an equal volume of water containing 0.1% formic acid
The mixture was analyzed using a UPLC-MS/MS method

Hydrocortisone-induced KYDS model: After 5 days of acclimatization feeding
72 male rats were randomly divided into the control group (CON)
The control group was gavaged with physiological saline
the model group was gavaged with hydrocortisone
and the treatment groups were gavaged with hydrocortisone in the morning and therapeutic drugs in the afternoon
The modeling and drug administration were performed simultaneously for 30 consecutive days
The rat model was considered established by observing the appearance of kidney-yang deficiency symptoms in model rats
Natural aging KYDS model: 75 male rats were randomly divided into the model group (MOD)
and FQGB-H group (2.57 g/kg) after being raised to 18 months old
whereas the other groups were gavaged with therapeutic drugs
all once daily for three consecutive months
To investigate the effects of hydrocortisone-induced KYDS rats on urine output
rats were placed in metabolic cages for 8 h with free access to water and food at weeks 1
and 4 after the establishment of the model and drug administration
Average urine output was compared with the model group and statistically analyzed
urine samples were collected for 8 h at weeks 3
The average urine output was compared with the control group and was statistically analyzed
the hydrocortisone-induced KYDS rats in each group were anesthetized by intraperitoneal injection of 3.5% hydrated chloral hydrate (10 mL/kg)
The immune organs are wiped clean with absorbent paper to remove surface blood and then weighed after removing the surrounding connective tissue
The index of the immune organs is calculated as the ratio of the weight of the immune organ to the weight of the experimental animal
A descriptive analysis method was adopted to elucidate the demographic characteristics and safety indicators as number
The PK parameters were expressed as the mean and standard deviation (SD)
United States) was used for statistical analyses and plotting
Statistical significance was set at p < 0.05
urine output in the hydrocortisone-induced KYDS model group increased at weeks 1 (8.4 ± 4.2 mL/8 h)
2 (7.8 ± 4.1 mL/8 h)
and 3 (8.9 ± 3.7 mL/8 h)
Urine output at week 4 (10.2 ± 3.4 mL/8 h) also increased
The GF and YG groups served as positive control drugs
The GF and YG group inhibited the increase in urine output of the model rats at weeks 2 (GF: 3.5 ± 2.6 mL/8 h
YG: 3.6 ± 2.3 mL/8 h)
3 (GF: 2.2 ± 2.4 mL/8 h
YG: 4.2 ± 2.3 mL/8 h)
and 4 (GF: 7.4 ± 2.8 mL/8 h
YG: 6.6 ± 3.1 mL/8 h)
with significant differences compared to the model group
The FQGB-L and FQGB-H groups significantly inhibited the increased urine output of the model rats from week 1 to week 4
the urine output of the FQGB-L group (4.9 ± 3.1 mL/8 h) and the FQGB-H group (5.8 ± 2.1 mL/8 h) was lower than the positive control group (GF: 6.5 ± 4.3 mL/8 h
YG: 7.7 ± 3.0 mL/8 h)
Effects of FQGBG on urine output in hydrocortisone-induced KYDS rats
For the KYDS natural aging model rats (Table 2)
the positive drugs GF and YG showed a reduction in rat urine production at weeks 10 and 12
The FQGB-L group significantly inhibited rat urine production at week 10 (4.6 ± 1.7 mL/8 h)
and the FQGB-H group significantly inhibited rat urine production at weeks 3 (4.3 ± 1.9 mL/8 h)
8 (2.3 ± 1.7 mL/8 h)
10 (2.9 ± 1.3 mL/8 h)
and 12 (2.1 ± 1.3 mL/8 h)
This indicates that the high-dose FQGBG group has a faster onset of action than the positive control group
Effects of FQGBG on urine output in natural aging KYDS rats
the adrenal gland (0.088 ± 0.014 mg/g)
the thymus (0.78 ± 0.14 mg/g)
and the spleen (1.32 ± 0.15 mg/g) showed significant atrophy in hydrocortisone-induced KYDS rats
and FQGBG all had antagonistic effects on adrenal atrophy
but only the FQGB-H group (0.100 ± 0.010 mg/g) showed statistically significant efficacy
and FQGB-H mildly antagonized hydrocortisone-induced thymus atrophy
YG and FQGBG also mildly antagonized hydrocortisone-induced splenic atrophy

The safety analysis of treatment-emergent adverse events (TEAEs) by system shows varying incidence rates across different dose groups and the placebo
The most common TEAEs included gastrointestinal disorders
with rates of 50% in the 12.5 g group
Investigations of abnormal laboratory results were also notable
especially elevated NAG enzyme levels (33.3%) and positive urine protein (33.3%) in the 75 g group
were observed in the 12.5 g (50%) and 25 g (16.7%) groups
General disorders such as heat sensation were frequent in the 125 g group (66.7%)
the overall incidence of TEAEs and adverse drug reactions (ADRs) were 56.3% in the treatment groups compared to 50% in the placebo group
with no statistical difference observed between the two groups
FQGBG contains diterpenoid alkaloids, including diester, monoester, and lipid alkaloids that are both active and toxic. The diester alkaloids have the highest toxicity, and the literature indicates that cardiotoxicity and neurotoxicity are the major toxic reactions of diester diterpenoid alkaloids in Aconitum carmichaelii Debeaux (Yang et al., 2018)
The AE related to cardiac damage was ventricular premature beat in the 12.5 and 25 g groups
Considering that ventricular premature beats existed at baseline
and there was no remarkable increase in the frequency of ventricular premature beats after dosing or an increased occurrence frequency with dose escalation
the conclusion that the ventricular premature beat was caused by the medication could not be drawn
Other AEs mainly manifested as abnormal laboratory results
Elevated NAG enzyme levels and positive urine protein in the 75 g group suggest a possible link to FQGBG’s diterpenoid alkaloids
These findings may indicate renal stress or damage
the clinical timing of using “toxic” herbal pieces is particularly crucial
Although the toxic plant metabolites present a risk of harming the body
they can yield significant therapeutic effects when used appropriately
the potential renal damage caused by FQGBG might be due to individual intolerance when the drug is applied to healthy subjects
emphasizing the need for careful monitoring and appropriate clinical use
Some AEs may be related to changes in the diet and lifestyle during hospitalization; therefore
is uncertain and further research is needed
FQGBG warms and invigorates the kidney yang; therefore
were likely due to the injured body fluid by excessively tonifying the yang and deficient fire flare-ups
whereas the blood concentrations of the three diester alkaloids in this study were all lower than the LLOQ
the blood concentration of the monoester alkaloid
which is 11.4 times the Cmax of BMA in this study
The above evidence demonstrates the safety of FQGBG at the studied doses
Vz/F of BMA gradually increased in the 25–75 g groups
suggesting that higher doses increased the distribution of BMA in the peripheral compartment
which may be related to the increase in T1/2
indicating that BHA’s metabolic pathways do not experience the same level of saturation within the studied dosage range
significant interindividual variability was observed in the PK parameters of BMA and BHA in healthy participants
Our analysis revealed that the CV for most PK parameters of both BMA and BHA exceeded 30%
It is might partly be attributed to the relatively small sample size in our study
A larger sample size would provide a more robust dataset
potentially allowing for a more accurate assessment of the variability and its clinical implications
and AUC0–∞ of BMA and BHA in the 100 g group were lower than those in the 75 g group
One possible reason for this was that the monoester alkaloid content in the new batch (116 μg/g) was lower than that in the previous batch (241 μg/g) during the clinical trial
similar results were not obtained in this study
metabonomics results can supplement the elucidation of the good safety and tolerability of FQGBG
which may be related to the improvement of polyuria symptoms by FQGBG in KYDS
The PK and safety of single-dose oral administration of FQGBG were investigated for the first time for healthy Chinese volunteers
The results indicated that the half-lives of FZ monoester alkaloids were prolonged
and there were significant individual differences
further evaluation of drug accumulation is needed in PK studies involving continuous administration
The pharmacodynamics and metabonomics results suggest that FQGBG exerts its efficacy by improving the function of the hypothalamus-pituitary-adrenal axis
effectively treating the increased urination caused by KYDS
and alleviating the symptoms of cold fear in KYDS rats through enhancing energy metabolism

Rock Tech Lithium has been granted up to 100 million euros from Brandenburg state government for its German lithium refinery in Guben
Rock Tech Lithium recently received a funding rejection from the German federal government
At the beginning of this month, the German-Canadian company Rock Tech Lithium received final approval from Brandenburg’s state government for its lithium hydroxide converter under construction in Guben
Now the state government has confirmed that Rock Tech Lithium can also expect up to 100 million euros in subsidies from the state government as well
Rock Tech turned to the Brandenburg state government for support after it became clear in an unexpected decision that it would not receive funds from the federal funding pot created in 2023 to establish a battery cell ecosystem in Germany
The company then announced that it wanted to rely on other support to complete its lithium converter in Guben and
that the Brandenburg Ministry of Economic Affairs
Labor and Energy has issued a binding letter of intent in which it pledges up to 90 million euros in funding for Rock Tech’s lithium converter in Guben
the Federal Railway Authority has promised a grant of up to 10 million euros for the site following a detailed examination of Rock Tech’s application for rail infrastructure
The federal government is also still on the hook
The application process for federal guarantees of up to 400 million euros to support the external financing of the project is underway
Rock-Tech CEO Dirk Harbecke remarked on the “major milestone” that the state government and railway authority grants represent for the company
Although he acknowledged it was “a big step towards the realization of the Guben Converter,” there appear to be numerous steps to go before the finance necessary to put the plant into operation comes together
“Together with the possible federal guarantees
we are targeting governmental financial support of up to 500 million Euros
In addition to these substantial subsidies
we have signed a binding feedstock agreement with a leading lithium trading house
for the procurement of raw material for our converters and received the full construction and operations permit approvals for Guben,” Harbecke explained
remarking that he was feeling “very confident that we will finalize the remaining financing steps for Guben in the coming months.”
Rock Tech Lithium is a German-Canadian company headquartered in Vancouver that extracts the raw material for the lithium hydroxide often used in electric vehicle batteries from its mine project in Georgia Lake in Ontario
This material is to be refined into battery-ready products in Guben
the company plans to produce around 24,000 tons of battery-grade lithium hydroxide per year in Guben from 2025
around 50 per cent of the raw materials are to be obtained from the recycling of old batteries
Mercedes-Benz has already secured an average annual supply of 10,000 tons of lithium hydroxide from Guben
Around 160 jobs are to be created in Guben
Rock Tech Lithium began construction of its plant in Guben in spring 2023 with preliminary approval at some risk
the Brandenburg State Environmental Agency gave the final green light for the plant following an immission control procedure with public participation
The approval process took a total of two years

Rock Tech Lithium’s (TSX-V:RCK) Lithium Converter Project in Germany has been recognised as a ‘strategic project’ under the EU Critical Raw Materials Act
The company says this designation underscores the importance of Rock Tech’s Guben Converter to the European battery materials supply chain and further accelerates its mission to provide Europe with sustainable
Rock Tech’s Guben Converter is poised to produce 24,000 tonnes of battery-grade lithium hydroxide annually — enough to power more than 500,000 electric vehicles
CEO Dirk Harbecke says the milestone not only affirms the strategic value of the Guben project but also positions Rock Tech as a key enabler of Europe’s green industrial future.
“We are honoured to be recognised as a strategic project by the European Commission and remain fully committed to advancing a secure
and independent lithium supply for Europe,” says Harbecke
the Critical Raw Materials Act is a cornerstone initiative aimed at securing a resilient and sustainable supply of 17 critical raw materials essential for Europe’s energy transition.
It enhances the EU’s capacity for extraction
reduces reliance on imports from third countries while upholding the highest environmental and social standards
With over 170 applications submitted to the European Commission
Rock Tech is proud that the Guben Converter was selected in this highly competitive process
The European Commission has announced that it will initially use 2bn EUR to support selected projects through loans
Rock Tech’s vision is to supply the electric vehicle and battery industry with sustainable
beginning with its proposed Lithium Hydroxide Converter in Guben
The second converter is planned to be built in Red Rock

VANCOUVER, BC, Nov. 4, 2022 /PRNewswire/ - Rock Tech Lithium Inc. (TSX-V: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) (the "Company" or "Rock Tech") is pleased to announce the completion of a bankable project study ("BPS") for the construction and operation of the Company's proposed battery grade merchant lithium hydroxide monohydrate converter and refinery facility (the "Converter" or "Project") in Guben
The results of the BPS which was conducted in collaboration with Wave International Pty and the Company's Finnish engineering partner show a significant improvement in the Converter's economics compared to the previous engineering study ("Converter Engineering Study")
released on November 29th 2021
and are expected to form the basis for the project financing discussions with potential lenders
Rock Tech's planned merchant LHM Converter in Guben
Germany is anticipated to be the first European lithium converter
with capacity to produce 24,000 tonnes of battery grade lithium hydroxide per year
a raw material urgently needed by the battery and automotive industries
The importance of lithium hydroxide is supported by the European Union's recent agreement to effectively ban the sale of new combustion engine vehicles from 2035
Such ban will reshape the European mobility sector and further accelerate EV production
leading to an increased demand for lithium hydroxide
Rock Tech's plant will be located in Guben
As announced in October 2021 the Company purchased a site within the existing Guben South industrial park
The site which covers a total of 12 hectares offers excellent accessibility by road and rail
key suppliers and customers reside in the region which is expected to become one of the leading battery and EV clusters in Europe
Transparent federal legislation and comprehensive state subsidy schemes further add to the region's attractiveness
The Converter is designed to process spodumene concentrates into battery grade LHM via the sulphation-causticisation (S-C) route
The basic process flowsheet was selected in the previous phase of the Project and was subsequently optimised using data supplied by equipment vendors and metallurgical test work completed during the study
"Our Guben Converter is an exceptional project as it will help address the increasing need for battery-grade lithium hydroxide
it will strengthen regional supply chains by offering a processing route for spodumene concentrates in Europe." Dirk Harbecke
The Company is very pleased that the technical and economic results of the BPS support the Company's strategy of building a converter in Germany
Although the BPS uses more conservative costing assumptions than the Converter Engineering Study
it estimates an increase in NPV and of project IRR
The BPS estimates a pre-tax NPV (8%) of USD 1,219 million an increase of USD 789 million (or 183 per cent) compared to the Converter Engineering Study
Recent inflationary pressures and global supply chain tightening have had a substantial impact on both the estimated capital expenditures and operating costs
Cost impacts are partially offset by more favourable lithium pricing assumptions based on current market price forecasts
"We remain conservative with our price forecasting," Mr
if we were to assume the current spot market prices for spodumene and lithium hydroxide remain stable
the pre-tax NPV of our Converter would increase substantially to USD 4,300 million and an IRR of 37.5 per cent"
The results of the BPS demonstrate the potential of Rock Tech's zero waste and ESG strategy
with approximately 96 per cent of the estimated 290,000 tonnes of by-product identified for potential utilization in other industries
Significant efforts have been undertaken to develop use cases for alumino‑silicates
In line with its conservative costing assumptions
Rock Tech has not yet reflected such opportunities in its revenue estimates
The city of Guben has commenced preparatory site activities such as grubbing and clearing
Rock Tech is expecting approval of its first partial permit (TG1) in Q4'2022 and the second and last partial permit (TG2) in Q3'2023
As a result of increased lead times for delivery of major equipment from suppliers
early construction works to the extent permitted under TG1 are anticipated to begin in Q1'2023
with start of commissioning planned to commence in Q2'2025
The BPS was a collaborative study with key contributions from Wave International Pty ("Wave") and the Company's Finnish engineering partner
The BPS demonstrates a high-level engineering definition and cost certainty with AACE Class 3 estimates for capital and operating costs
The BPS incorporates recent metallurgical test work
including vendor test work conducted for key process packages using spodumene feedstocks from a range of prospective suppliers
the BPS describes a path forward to realize value-add opportunities for the Converter residues
which are envisioned as in-demand feedstocks for the domestic building and construction industries
Rock Tech also recognizes the risks associated with supply chain disruptions due to the impacts of the ongoing war in Ukraine
fluctuating currency exchange rates and energy prices
In an effort to manage such risks and provide a robust financial outlook for the Converter; such risks were taken into account when preparing the BPS
This resulted in an increase in capital expenditure and operating cost estimates for the Converter compared to the Converter Engineering Study
the start of commissioning of the Project has been moved to Q2'2025 to account for such evolving social
Rock Tech is currently embarking on a Front-End Loading Stage 3 (FEL3) study to finalize basic engineering to support a final investment decision
Key economic results of the BPS are reported below:
Life-of-Project C1 Operating Costs excluding spodumene costs
Average spodumene concentrate price paid USD/t(5)
1. See "Key Assumptions and Sensitivity Analysis" section below for further details
2. Key metrics are calculated on nameplate annual production of 24,000 tonnes of LHM over 25-year life of project (as applicable)
6. Based on market forecasts projected over 25-year life of project
The BPS estimates total initial capital costs of approximately USD 683m for the Converter (determined to be within a nominal accuracy of +/-20%)
including approximately USD 485m in direct capital costs
USD 130m in indirect capital costs including USD 40m in owner's costs and a weighted contingency of 10%
The initial capital cost estimate includes the capital requirements to engineer
construct and commission the Converter and covers project implementation costs for the period from final investment decision to the end of commissioning of the Converter
It also includes early procurement of long lead items and potential early site works
Initial capital cost estimates were generated from vendor basic design
vendor quotations and market data as of a base date of June 30
A breakdown of the estimated initial capital cost is presented in the following table:
ESTIMATED CAPITAL COSTS (1) in USDm

3. Indirect and owner's cost estimates were derived from factors and experience deemed to be reflective of current estimate accuracy
including the continued development of the Converter's engineering design
have resulted in an increased initial capital cost estimate compared to the Converter Engineering Study
Key price escalations have been assumed for plant costs relating to raw material prices
resulted in an improved engineering definition of the Converter as well as an improved procurement package scoping
The basic engineering design supports an AACE Class 3 capital cost estimate with an accuracy of +/-20% for overall plant and infrastructure
including higher levels of accuracy at +/-10% for key process packages including the kiln and crystallisers
The BPS considers increased labour and material costs because of global skilled labour and supply chain disruptions
Rock Tech expects such disruptions to normalize throughout 2023 and has allowed for inflation in the capital cost estimate accordingly
Rock Tech intends to continue to orient its procurement and contracting strategies toward reducing capital cost and execution risk during the FEL3 study
The average annual operating costs of the Converter are estimated at USD 114m per year (determined to a nominal accuracy of +/- 20%)
Prices used to develop operating cost estimates were market-based enquiries and analyst reports
All activities relating to the procurement of materials
and processing to produce an ex-works LHM product were included in the operating costs
Spodumene procurement has been excluded in the summary below
Reagent pricing was mostly received in US Dollars with other costs and pricing being received in Euros
An exchange rate of USD 1: EUR 1.042 was assumed for the BPS
A breakdown of the estimated average annual operating cost over the life of the Converter excluding the cost of Spodumene Concentrate is presented in the following table:
1. Operating costs are calculated on nameplate annual production of 24,000 tonnes of LHM over 25-year life of project
The operating cost estimate of the BPS is greater than the operating cost estimate of the Converter Engineering Study with such increase primarily driven by higher estimated maintenance costs
The BPS assumes that the Converter will have a 25-year life span and a nameplate annual production of 24,000 tonnes of LMH from approximately 173,500 tonnes of spodumene concentrate
which is intended to be sourced from third parties and via RTT (as defined below)
The discount rate utilized for financial analysis is 8%
A weighted average price of spodumene concentrate of USD 1,532 per tonne is assumed
reducing from a peak price of USD 4,768 per tonne in 2023(1)
The following exchange rates were considered: USD to EUR= 1.0417; CAD to USD= 0.7189 (current exchange rates: USD to EUR = 1.0037; USD to CAD = 0.7382) (2)
a sensitivity analysis was conducted on the Converter's pre-tax NPV and pre-tax IRR to key variables
including spodumene concentrate price and LHM price
the key variables were changed between +/-30% at 10% intervals while holding other variables constant
The Project is most sensitive to fluctuations in lithium hydroxide and spodumene concentrate prices as well as changes in USD-to-EUR exchange rates
Spodumene concentrate price and LHM price sensitivities are presented in the tables below:
SPODUMENE CONCENTRATE PRICE – SENSITIVITY ANALYSIS
The Converter is expected to comprise a pyrometallurgical and hydrometallurgical chemical plant that uses various reagents to extract the lithium from spodumene concentrate to produce a purified LHM product
The process flowsheet has been designed to incorporate process unit operations typical to lithium refineries using the sulphation route
Proven technology within the lithium industry was used to minimise technical risk and time to market
Additional process equipment beyond a traditional flowsheet has been included specifically to give the plant a large operating envelope and thus ability to process a wide range of feedstock
Lithium recoveries based on analysis of a multi-phase test work program covering a broad variety of spodumene concentrates and as simulated in the mass and energy balance indicates a potential average leach extraction of 94.5%
a projected lithium loss in other parts of 3.5% and therefore an overall lithium recovery to 91%
Critically the metallurgical testwork included vendor testwork results for key process equipment supplied by FLSmidth & Co
A/S (Kiln and Roasting circuit) and JordProxa Pty
Ltd and GEA Group AG (Crystallizer Circuit)
To allow for operational experience factors and the possible effect of spodumene reactivity
the overall recovery has been discounted to 86% in the process design criteria and subsequently the cashflow model
This conservative approach to recovery has the effect of defining the requirement for higher spodumene and reagent feed rates thereby creating sufficient processing capacity to achieve higher recoveries and process efficiencies once the process has been optimised
The Project is expected to generate approximately 290,000 tonnes of by-products per year
Studies conducted by Rock Tech show that as a result of their chemical composition the vast majority of these non-lithium products have the potential to be utilised in other industries
including government accreditation following commencement of production
In line with Rock Tech's commitment to highest ESG standards
the BPS describes significant efforts which have been undertaken to develop a use case for the following materials
representing 96% of the by-product production from the Converter:
Despite the positive outlook for such by-product use cases the financial results of the BPS do not attribute additional revenue to these by-products
in line with the conservative approach taken in the BPS
The study assumes sodium sulphate anhydrous is a saleable product while all other by-products are assumed to be disposed of in waste management facilities at Rock Tech's expense
Offtake offers and Letters of Intent for by-product disposal have been secured for 98% of the non-lithium products
Rock Tech believes there is a significant opportunity to improve project cash flow by finalizing the by-product use cases and continues to develop and evaluate these cases
consumables and spare parts must be transported
is expected to be sourced from mines in Australia or Canada
Rock Tech has recently announced to have entered into a definitive agreement to form a joint venture entity with Transamine Holdings and Investments Limited to form RTT Lithium SA ("RTT")
(see the Company's press release dated October 24
RTT will manage the procurement of spodumene concentrate from global mining companies and spodumene producers and arrange related logistical and storage services
Based on the Company's supplier discussions
are expected to be sourced in Germany and transported to the Converter by train or truck
Rock Tech has selected preferred logistics partners for the full supply chain from Spodumene shipping
port receival and bonded warehousing in the port of Nordenham
rail handing systems and rail transport to Guben
The Company has also selected transport systems and preferred suppliers for all other materials handling requirements inbound and outbound from the Converter site in Guben
The BPS provides an updated Project schedule compared to the Converter Engineering Study
Site activities have commenced with grubbing and clearing expected to be completed before the end of 2022
Based on initial submissions to government authorities the permitting process must be completed in accordance with the Federal Immission Control Act of Germany
Rock Tech has agreed that the permitting application will be submitted in two parts:
As a result of increased lead times from major equipment suppliers
early construction works to the extent permitted under TG1 are anticipated to begin in Q1'2023 with start of commissioning planned from Q2'2025
As the Company moves into the next phase of engineering
the Company's Finnish engineering partner has been engaged to prepare the FEL3 study
a level 3 resource-loaded execution phase schedule will be developed
incorporating detailed supply and installation schedules obtained from vendors during the competitive tendering phase

A leading lithium developer in northwestern Ontario has received official approval to press on with building Europe’s first lithium processing plant in Germany
Rock Tech Lithium said it’s received construction and operational permits for a refinery in Guben
Rock Tech is calling this a milestone moment both for the company and the German battery value chain
The occasion was marked with a permit ceremony in Potsdam attended by Brandenburg state officials and various government dignitaries
The start of construction has yet to be determined.
Rock Tech CEO Dirk Harbecke said the permits provide them with some validation and the impetus to chase down that last bit of project financing from lenders
“The permits not only allow us to now move into the last stage of financing for the project
but they are also proof that our concept works and the Guben converter will serve as the blueprint for our other refinery projects worldwide,” he said
“We expect to finalize subsidy negotiations and equity term sheets with strategic partners soon
The credit approval process with our banking partners will follow shortly after and we aim to take the final investment decision (FID) in Q3 this year."
But the feed for the Guben refinery will not come from Rock Tech’s Georgia Lake lithium deposit near Lake Nipigon but through international brokers
Rock Tech inked a feedstock agreement with C&D Logistics
a major mover in the lithium space with connections to spodumene mines in Australia
Rock Tech has already signed off-take agreements with major automakers.
There are separate plans to construct a second refinery in Red Rock to accept material from its Georgia Lake spodumene project
a future mine situated 17 kilometres south of Beardmore and 145 kilometres northeast of Thunder Bay
Last spring, Rock Tech signed a long-term lease with its development partners, BMI Group, to secure a site at a former paper mill in Red Rock
The groundbreaking will take place sometime in 2025
The mined material will be transported from Georgia Lake
The spodumene — a widely used and preferred rock because of its high lithium content — will be crushed into a concentrate and trucked to Red Rock
the material will be converted into a a battery-grade material
that’s in demand in the electric vehicle market
Rock Tech is billing the Red Rock site as a regional hub processing site that would source lithium from other mines in the region and possibly raw material as a recycler of discarded batteries
VANCOUVER, BC, May 14, 2023 /PRNewswire/ - Rock Tech Lithium Inc. (TSXV: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) (the "Company" or "Rock Tech") is pleased to announce that it has reached a significant milestone in the preparation of construction of its lithium hydroxide converter and refinery plant in Guben
with the completion of the Front-End Loading stage 3 study ("FEL3")
The study includes detailed specifications for construction
along with a purchase-ready major equipment cost estimates
The study was finalized by the Company's German subsidiary Rock Tech Guben GmbH in collaboration with engineering partner AFRY AB
paving the final way for the Project's construction phase
The profitability has been estimated to have a post-tax NPV (8%) of EUR 1,194m (USD 1,246m) - an increase of 43 per cent compared to the previous Bankable Project Study2
Rock Tech has appointed Deutsche Bank AG as placement agent for the Company's Converter-related financing
1 Please note that all USD to EUR conversions in this document are based on an average exchange rate of USD to EUR = 0.9579
disclosed on 04 Nov 2022 within the release "Rock Tech Lithium completes Bankable Project Study for its Guben Converter Project"
and the Project is prepared to move to construction phase including final procurement negotiations and detailed engineering design
The FEL3 study estimates the project's profitability at a post-tax NPV (8%) of EUR1,194m (USD 1,246m) - an increase of 43 per cent compared to the Bankable Project Study
the increased long-term price assumptions of analysts for lithium hydroxide caused by the continued forecast of very high demand
lead to a higher basis for the margin calculations
The FEL3 results in a much more accurate cost estimate with a variance of only +/-10% (AACE Class 2) and is based on existing definite offers of mainly European suppliers and service providers supporting purchase-ready major equipment cost estimates
it can be clearly noted that the planning of capital expenditures remains stable and only increases by 4%
Execution planning and basic engineering is now comprised for all plant areas
Efforts involved significantly increased levels of basic engineering deliverables
which was in progress at the time of the BPS publication
has now been completed and was provided for expert review and interpretation by industry specialists
Completion of these tasks has allowed for finalization of plant equipment selection and flowsheets
Lithium recovery assumptions made in the BPS have proven to be accurate with no changes required to production assumptions
A forward metallurgical testing work plan has been developed which will perform final optimizations
with material from the selected spodumene concentrate supplier
A competitive tendering process has been kicked off
with the assistance of an independent expert
Procurement and Construction Management (EPCM) partner for project execution
Rock Tech is also pleased to announce that it has selected Deutsche Bank AG as a highly experienced placement agent with a proven track record in major equity financings
"We are very pleased to have partnered with Deutsche Bank
to lead our equity raising and partnership activities for the Converter financing
The completion of our latest detailed engineering study further substantiates the profitability and attractiveness of our project
and we are confident the next months will yield strong financing partnerships." Sonja Rossteuscher
Rock Tech's lithium hydroxide converter and refinery plant in Guben
Germany is planned for a production capacity of 24,000 tonnes of battery-grade lithium hydroxide monohydrate per year
It is going to be able to process spodumene concentrates from various origins
be it from the Company's own mineral project Georgia Lake
Rock Tech has obtained the first partial permit ("TG1") issued by the Brandenburg State Office for Environment in March 2023
The permit allows start of construction for all non-process buildings and site infrastructure and approves the general plant layout and functions for the spodumene to lithium hydroxide conversion
The Company submitted the second partial permit ("TG2") in November 2022 and expects approval by Q4 2023
Targeted start of commissioning remains on track for Q4' 2025
with first battery grade LHM being produced in Q1' 2026
Key economic results of the FEL3 are reported below:
Average spodumene concentrate price (6% Li2O) paid
Key metrics are calculated on nameplate annual production of 24,000 tonnes of LHM over 25-year life of project (as applicable)
For more details on exchange rates see footnote 1
Operating costs are calculated on nameplate annual production of 24,000 tonnes of LHM over 25-year life of project
Based on market forecasts projected over 25-year life of project
The FEL3 initial capital costs have increased by 4% in Euro terms compared with the BPS as the last published study phase3
Improvements to the capital expenditure (CAPEX) estimate include improved engineering completed during the FEL3
and a refined understanding of freight requirements; all of which served as the basis for the FEL3 estimate and support a Class 2 level of certainty
to be done in close coordination with an EPCM contractor
will provide opportunities to further de-risk the CAPEX estimate by highlighting key areas where further negotiation with preferred suppliers will yield improved results
It is planned that the procurement team will work in conjunction with the selected financing groups to ensure a high level of confidence can be obtained from supplier pricing. This will allow the Company to make the Final Investment Decision in the second half of 2023
3 Given that the project is being realized in Germany and is mainly European financed
the increase in costs is given here in EUR
An information of the increase in USD would be arithmetically higher and would amount to 11.6%
2.6% of this increase are attributable to higher material quantities and risen unit rates
The remaining 9.0% of the increase is caused by devaluing foreign exchange rate changes of EUR and USD

As the German publication Handelsblatt writes
citing information from Rock-Tech CEO Dirk Harbecke
the company received a surprise rejection notice from the Federal Ministry of Economics on Monday
The company had been counting relatively firmly on federal funding from the pot called ‘Resilience and sustainability of the battery cell production ecosystem’
The funding guideline was launched by the Ministry of Economic Affairs last year as part of the ‘Temporary Crisis and Transition Framework’ (TCTF) created by the EU Commission
it is actually the target group of the aforementioned funding programme
Economics Minister Robert Habeck said that investments in the battery value chain would contribute to Europe’s strategic sovereignty
“It is disappointing that we are now not receiving the funds from the TCTF programme,” CEO Harbecke is quoted as saying in Handelsblatt
“We assume that the state of Brandenburg will be able to mobilise sufficient regional funding to realise the project”
The local community of Guben also has a “great interest” in the project being completed
Construction of the converter plant in Guben began at the end of March 2023
with the company stating at the time that the processing plant would go into operation in mid-2025 and produce battery-grade lithium hydroxide from 2026
It also stated that the planned total investment volume for the plant would be around 650 million euros
Harbecke now spoke to Handelsblatt about a planned investment of 800 million euros
with “up to 200 million euros” in federal subsidies expected to be received via the rejected application for funding
Both at the ground-breaking ceremony and in view of the cancellation of production
Rock Tech emphasises that its converter in Guben is in line with the EU’s new strategic goals of securing twelve times the demand for lithium by 2030 and at the same time processing 40 per cent of lithium regionally
The company is referring to a new EU law on securing critical raw materials
“Our plant in Guben is the most advanced converter project for lithium in Europe,” emphasised Harbecke at the start of construction just over a year ago
Now he adds: “If the EU wants to achieve its goal of bringing 40 per cent of the processing of critical raw materials to Europe
then Europe needs twelve lithium converters
handelsblatt.com (in German)
Canadian lithium development firm Rock Tech Lithium has begun construction on its first lithium hydroxide conversion plant in Guben
According to the company, the project aligns with the European Union’s strategic goals to meet 12 times the demand for lithium by 2030 while processing 40 percent of it regionally
The plant will process lithium-bearing hard rock into battery-grade lithium hydroxide for the cathode and battery industry, which will help accelerate the EV mobility transition and facilitate battery and cell production
the shift towards electric mobility also means a change in our supply chains,” said Markus Schäfer
Member of the Board of Management of Mercedes-Benz Group
“Three goals are central to us: sustainability
raw material security and localization of procurement.”
“Today's groundbreaking in Guben is therefore another milestone for Mercedes-Benz towards the sustainable production of state-of-the-art batteries
When it comes to our lithium supply here in Europe
Rock Tech will play a key role for Mercedes-Benz in the future,” Schäfer added
The Guben Converter is the first of five converters that Rock Tech plans to build in Europe and North America
The project is expected to start operations in mid-2025 and produce qualified battery-grade lithium hydroxide from 2026
“Our Guben Converter is spearheading the lithium refining industry in Europe,” said Dirk Harbecke
sustainable processing and strategic partnerships
As a Canadian-German company we are building bridges and opportunities across the Atlantic and further to Australia
the world largest global lithium spodumene producer.”
Rock Tech is a cleantech company with operations in Canada and Germany
It plans to build lithium converters at the door-step of its customers
to guarantee supply-chain transparency and just-in-time delivery
beginning with the company's facility in Guben
The Chinese company Botree Cycling is planning to build a recycling plant for electric vehicle batteries and an education and training centre for battery recycling specialists in Guben
Another industry player is also setting up shop in Guben
With its decision for the Brandenburg location
Botree Cycling is following in the footsteps of the German-Canadian company Rock Tech Lithium
which is setting up a production plant for lithium hydroxide in Guben
Botree Cycling’s battery recycling plant is scheduled to go into operation in 2025 on the Guben South industrial estate – the year in which Rock Tech also plans to start up its facilities
both sides signed a letter of intent in the middle of the month to acquire two plots of land with an area of 3.8 hectares
this is the company’s first location in Europe
Botree Cycling’s planned investment volume in Guben is up to 100 million euros
Around 100 people will be employed on site during ongoing operations
the company is open to expansion at the location
The city is very pleased with the settlement: it has “once again proven that it [the city]
with its long industrial tradition and existing infrastructure
offers the best conditions for becoming a central component of the battery value chain and thus part of the Brandenburg e-mobility cluster”
The German portal Cleanthinking.de lists a few more key points about the company and its recycling technology
Botree Cycling in China is called Suzhou Botree Cycling Sci & Tech Co
Ltd and in October 2022 it “closed an unspecified Series A financing round”
The workforce is said to consist of experts from the Chinese Academy of Sciences or KU Leuven

the control of age-related disease susceptibility and prognosis faces greater challenges
There is an urgent need for a strategy to maintain the vitality of elderly people
the effect of Renshen Guben (RSGB) oral liquid was investigated on an accelerated aging mice model of thyrotoxicosis by conventional detection methods combined with multiomics technology
The results showed that RSGB increased the number of neutrophils and lymphocytes
and increased the levels of complement and antimicrobial peptides
which indicated that RSGB improved the immunity of thyrotoxicosis mice at the cellular and molecular levels
RSGB corrected malnutrition in thyrotoxicosis mice by improving anemia
RSGB significantly reduced the lipotoxicity by reducing the level of fatty acids
thus increasing the level of docosapentaenoic acid (DPA) and bile acids
which contributed to improve immunosenescence
The intestinal defense ability of thyrotoxicosis mice was enhanced with the increase of bile acids and lactic acid bacteria by the RSGB treatment
The plant metabolomics analysis showed that there were various active components in RSGB oral liquid and medicated serum
RSGB protected the thyrotoxicosis mice against aging by improving immunosenescence
It will be beneficial for improving the disease susceptibility and prognosis of the elderly
bile acids interact with the intestinal flora and jointly affect intestinal health
the levels of bile acids were found to be significantly decreased in thyrotoxicosis mice
Because of the lack of bile acids to control the intestinal flora
the intestinal defense ability may be declined in thyrotoxicosis mice
It suggests that any strategy that can regulate bile acid homeostasis and the intestinal flora balance may have great potential for maintaining immunity and anti-aging
the influence of RSGB on the intestinal flora was also detected
and plant metabolomics were combined to clarify the action mechanism and material basis of RSGB
The RSGB oral liquid was provided by Lunan Hope Pharmaceutical Co.
It was prepared from 10 herbs: Panax ginseng (Ren Shen
The preparation process was as follows: The volatile components from Cortex Moutan were extracted by distillation
and the drug residue and liquor were retained for further use
Panax ginseng and Cornus officinalis were prepared by refluxing 60% ethanol twice; the extracts were combined and filtered
and the filtrate and the drug residue were retained for further use
The above-mentioned two kinds of drug residues and the remaining seven herbs were decocted with water which was added for two times; the decoction was filtered
Ethanol was added to 60% and then combined with the previous Panax ginseng and Cornus officinalis ethanol extraction solution and filtered
Ethanol was removed by concentration; then
The volatile components of Cortex Moutan and 100 g of syrup were added
The oral solution was obtained after sterilizing
The amount of original drug in each milliliter of oral liquid was 0
Four- to 6-week-old healthy female KM mice (SPF grade) with body weight of 16–18 g were purchased from Ji’nan Pengyue Laboratory Animal Breeding Co.

The model group was administered with vehicle (purified water)
thyroxine tablet suspension was given by an intragastric dose of 320 mg·kg-1
the animals were subjected to fasting on the night before dissection
Blood was taken from the main abdominal vein after the administration of anesthesia with 60 mg·kg-1 pentobarbital sodium
Blood was injected to EDTA-K2 vacuum tubes for routine blood test
Blood and feces were collected for multi-technology detection
Anticoagulant blood was used for routine blood test and flow cytometry
Serum was taken for biochemistry detection and proteomics and metabolomics detection
Feces were collected for metabolomics and microbiomics
Plant metabolomics was used for Renshen Guben oral liquid and drug-containing serum
In order to investigate the safety of the RSGB oral liquid
and pathological indexes of mice were detected in mice treated with RSGB oral liquid alone
The mice were randomly divided into two groups: control group (N) and RSGB group (W)
the RSGB oral liquid was administrated by an intragastric dose of 20 ml·kg-1 at twice a day for 30 days
the purified water was administrated by an intragastric dose of 20 ml·kg-1 at once a day for 30 days
EDTAK2 anticoagulant whole blood was taken for routine blood test
The routine blood tests were carried out by using Sysmex XN-1000v (B1) automated hematology analyzer (SYSMEX Co.
The positive rates of CD4+ and CD8+ T lymphocyte subsets were analyzed by flow cytometry
3 ml of red blood cell lysis buffer was added to each sample to completely lyse red blood cells
the samples were washed and re-suspended with DMEM to 1 × 106 cells·ml-1
The cells were transferred to 48-well plates with 100 μl volume of each well
and 2 μl of cell activation cocktail (BD Biosciences) and 1 μl of BrefeldinA (BD Biosciences) were added to each sample and incubated at 37°C for 6 h
After washing and re-suspension with phosphate-buffered saline
the samples were incubated with specific fluorescent antibodies (BD Biosciences) of PerCP-Cy™5.5 Hamster Anti-Mouse CD3e (0.5 μl/sample)
FITC Rat Anti-Mouse CD4 (0.2 μl/sample)
and APC-H7 Rat anti-Mouse CD8a (0.5 μl/sample) for 30 min at room temperature in the dark according to the manufacturer’s guidelines
The samples were analyzed by using the CytoFLEX flow cytometer (Beckman Coulter Life Sciences)
and the data were analyzed by the CytExpert software (Beckman Coulter Life Sciences)
To further determine the levels of CD4+IFN-γ+ T lymphocyte subsets
the cells treated in the previous step were fixed with 500 μl of 4% FA for 20 min in the dark and ruptured with 1 ml of Permeabilization Wash Buffer (BD Biosciences)
the cells were stained with PE Rat Anti-Mouse IFN-γ (1.25 μg/sample) for 30 min
Serum biochemical analysis was detected by using the BS-800 automatic biochemistry analyzer (Shenzhen Mindray Bio-Medical Electronics Co.
40 ul serum was used for the proteomics analysis
The protein concentration was determined by the BCA method
10 μg protein of each sample was separated by 12% SDS-PAGE
The digested peptides were desalted by C18-Reverse-Phase SPE Column
RP separation was performed on an 1100 HPLC System (Agilent) using an Agilent Zorbax Extend RP column (5 μm
The separated peptides were lyophilized for mass spectrometry
All analyses were performed by a Q-Exactive HF mass spectrometer (Thermo

The correlation analysis showed that several RSGB metabolites positively interacted with the probiotics
the mutual promotion between LAB and RSGB metabolites in this study contributed to maintaining intestinal health
there are many components that can interact with the intestinal flora
In addition to interacting with the intestinal flora
the active components in RSGB also have direct effects
Clarifying these components is very important so as to expand the cognition of TCM
UPLC–MS/MS-based plant metabolomics methods were carried out to analyze the molecular composition in both RSGB oral liquid and the serum of RSGB-treated mice
The results showed that there were many kinds of substances in the oral liquid and the serum of RSGB-treated mice
These substances might be the active ingredients in the RSGB oral liquid
RSGB also had higher levels of amino acids and organic acids; they were all nutrients for the body
the ingredients in RSGB oral liquid and medicated serum had a variety of pharmacological activities
which corresponded to the pharmacodynamic test results in this study
They are the material basis for the anti-aging effects of RSGB on thyrotoxicosis mice
The illustration of the RSGB action mechanism is displayed in Figure 7
The RSGB treatment significantly improved hypoproteinemia in thyrotoxicosis mice by the upregulation of Alb
The recovery of the above-mentioned proteins not only indicated the improvement of malnutrition but also was beneficial for maintaining defense ability
The RSGB treatment improved immunosenescence by reducing lipotoxity
RSGB alleviated lipotoxity by decreasing the level of lipotoxic lipids and lipid-like molecules such as free fatty acids

and bile acids was beneficial for maintaining defense capacity
as was the upregulation of lactic acid bacteria in the intestine
RSGB improved the aging features of thyrotoxicosis mice from the following aspects: increasing the number and function of immune cells
It suggested that RSGB could restore the resilience of elderly people
protecting them from the risk of infection
which is of great significance for personal health and social burden
The safety study for 30 consecutive days showed that no toxicity was found
This study verified the anti-aging effect of RSGB on thyrotoxicosis mice and clarified its mechanisms and material basis
In addition to the anti-aging effect obtained by testing the blood indicators
RSGB might also have the organ-protective effect because of its multiple protective effects
and the next studies will examine organ-protective effects to more fully demonstrate the anti-aging effects of RSGB
the multi-element and multi-effect systematic treatment strategies of TCM have played an important role in ensuring the health of the Chinese people
It is believed that with the continuous research and understanding of TCM
it will also play a greater role in ensuring global human health in the future

a supplier in the automotive industry commits to supply a minimum of 250,000 dry metric tonnes of spodumene concentrate feedstock for the Company's conversion facility
Binding Feedstock Offer for Guben Lithium Plant Secured
announces that it has received a binding feedstock supply offer from Castelburg Industrie GmbH
a supplier in the automotive industry commits to supply a minimum of 250,000 dry metric tonnes of spodumene concentrate feedstock for the Company’s conversion facility in Guben
Germany over an initial five-year term of the envisaged agreement starting in 2024
The execution of the binding supply agreement based on the terms of the Offer is subject to a positive result of ongoing due diligence
Under the supply agreement Rock Tech will annually source up to 60,000 dry metric tonnes from Castelburg’s source in Salta
The price of the spodumene concentrate is based on a discount to market prices and will be adjusted for the actual Li2O content
The supply agreement further provides for a potential increase of volumes and extension of the initial term subject to mutual agreement by the contract parties
Rock Tech’s Chairman and CEO comments
“This is an important milestone for Rock Tech and the advancement of our Guben project
as independent 3rd party feedstock is a key step to finalize the financing for our German converter
Castelburg is another strong European industry partner backs us
offering its relationships in South America to support our feedstock sourcing strategy.”
The Guben converter will be Germany’s first spodumene concentrate to lithium hydroxide refinery with an annual name plate capacity of 24,000 tonnes battery-grade lithium hydroxide
The receipt of the full permit to build and operate the plant is expected for early 2024
The current market outlook for Europe predicts that Lithium conversion capacity will be the major bottleneck in building a sustainable and resilient battery supply chain
Rock Tech’s Guben converter will hence be vital for the European battery industry and supply lithium chemicals for approximately 500,000 electric vehicles
including all logistics handling and financing will be facilitated by RTT Lithium SA
a 50%/50% joint venture established by Rock Tech and Transamine SA
the positive finalization of which is condition precedent for the execution of a supply agreement
VANCOUVER, BC, May 24, 2023 /CNW/ - Rock Tech Lithium Inc. (TSXV: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) (the "Company" or "Rock Tech") is pleased to share the findings of a Life Cycle Assessment (LCA) for battery-grade lithium hydroxide monohydrate (LHM) from its planned conversion plant in Guben
The study was carried out by the Fraunhofer Institute for Environmental
and Energy Technology ("Fraunhofer UMSICHT") in accordance with ISO 14040 (2006) par
the carbon footprint of battery-grade LHM from Guben is 10.5 kg per kilogram
It also shows the ability to considerably reduce emissions to 5.4 kg
When compared against an International Energy Agency (IEA) special report
Rock Tech's base case footprint for LHM from hard rock is 30 percent lower
"We want to contribute to zero-emissions and battery electric vehicles
accepting the challenge to reduce the environmental impact of our lithium hydroxide
The LCA shows that we and our partners in the market have the power to bring about this change through commercial decisions."
The renowned German Fraunhofer UMSICHT has evaluated the "cradle-to-gate" environmental impact of battery-grade LHM to be produced at Rock Tech's Guben Converter
The base case carbon footprint is projected to be 10.5 kg CO2-eq/kg LHM
encompassing all upstream emissions and an assumed distance of transit from Australia to Germany
The main sources of emissions per 1 kilogram of LHM in the LCA scenarios were attributed to energy supply for the Guben Converter with 4.3 kg CO2-eq (average grid mix electricity
mining and concentration of spodumene with 3.8 kg CO2-eq
and transportation and shipping of spodumene concentrate with 0.7 kg CO2-eq
When compared against the International Energy Agency's (IEA) special study on "The Role of Critical Minerals in Clean Energy Transitions" (also see Table 1)
Rock Tech's base carbon footprint is 30 percent lower
through mainly careful choice of suppliers
the Company has the ability to reduce emissions to 5.4 kg CO2-eq./kg LHM
which could be compared to the estimated carbon footprint of LHM from brine in the IEA special report
credits of -1.0 kg CO2-eq./kg LHM are given to one by-product by applying the avoided burden approach.1 The assessment also shows different scenarios that could cut the emissions in half by commercial choice of suppliers alone
Changing from an average grid mix to exclusively renewable sources might reduce the footprint by more than 20% compared to the baseline scenario
Spodumene mining also has a lot of potential for improvement
Considering of supplies from Rock Tech's Georgia Lake Project in Ontario
or reduced emissions claimed by some existing Australian mining companies
The LCA did not take into account Rock Tech's ambitions2 towards a zero-waste scenario because the exact quantification of its influence could not yet be determined clearly
the targeted use of by-products remains a strategic priority that could bring additional emission-saving potential beyond the scope of the present study
The same holds true when substituting natural gas with hydrogen
These measures will provide further considerable benefits in the future
credits from by-product utilization are not accounted for in the net sum emissions of Rock Tech LCA
although Rock Tech supports avoiding carbon emissions in an industry beyond the scope of the LCA

GP Papenburg and Schwenk Zement Collaborate for Closer Commercial Utilisation of Lithium By-Products" issued 30 January
DATA AND CONFORMITY OF THE STUDY The LCA takes into account several impact categories and examines the possible environmental impact of products
This method ensures that all of the essential factors are assessed for a sustainable decision-making process
Secondary data is being used to calculate the carbon footprint of spodumene mining and concentration
All LHM manufacturing processes rely on primary data
The primary data originates from mass and energy flow sheets (activity data) from the Company's Bankable Project Study
the LCA has been critically assessed by an independent third party (DEKRA) in accordance with ISO 14071 (2016) paragraph 4.3.3 and ISO 14044 (2006) paragraph 6.2
The Company created a comparison of Rock Tech's carbon footprint to the IEA special report (see table 1)
which is not subject to the LCA done by Fraunhofer or third-party verification by DEKRA

(TSX-V: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) (the "Company" or "Rock Tech") is pleased to provide a project update on its mining and converter projects
Rock Tech has made substantial progress in the engineering
development and financing of its two assets
the lithium hydroxide converter in Germany and the Georgia Lake mining project in Canada
The Company has also started the planning and site selection process for its second converter
Rock Tech broke ground on its lithium hydroxide monohydrate (LHM) converter in March 2023
Site access has been secured and basic engineering for the plant has been completed through a series of three thorough engineering studies including the recent Front-End Loading Stage 3 study (FEL3)1
Test piling and loading tests have been completed and geostatic modeling results are expected in the next weeks
Final approval to build and operate the converter is expected in Q4 2023 and the Company plans to start construction once the final permit is granted
Construction is projected to be completed by the beginning of 2025
First production output is planned for Q3 2025
After this initial ramp-up phase Rock Tech will begin to produce battery-grade lithium hydroxide starting in Q1 2026.
Utility contracts and procurement of major equipment parts including the pyrometallurgical package
hydrometallurgical package and crystallizer have been prepared
Instrumentation and Control (I&C) for the production plant are defined including operating strategy with regards to digitalization
residues and chemicals have also been defined
The selection of an EPCM contractor is in its final stage and selection will be finalized in the coming weeks. The city of Guben has finished a railway connection tender for the site. The supply of additional feedstock for the converter is in final stages as well
1 See the Company's press release titled "Rock Tech Lithium Inc
completes Final Engineering Study before Construction of its Lithium Converter and Mandates Deutsche Bank as Placement Agent" May 14
German permitting allows for one single permit to build
This permit requires extensive knowledge of emissions
adherence to government regulations and fire protection among other related aspects
The application for the second part of the permit that relates to all process infrastructure was submitted in 2022 and is expected to be granted by Q4 2023
Rock Tech is making rapid progress with subsidies
The Company expects to receive approximately 450m EUR in debt from prominent European Banks
the due diligence for the credit approval is already underway
Deutsche Bank has been mandated as placement agent for the converter to secure 350m EUR in equity and subsidies from investors and the government
Equity investments in Germany will be on the asset level to ensure minimal dilution of the holding company publicly listed in Canada
are attracting significant interest from global investors looking to acquire a direct stake
negotiations are ongoing with major companies in the lithium
battery production and automotive sectors to form strategic partnerships
Negotiations are expected to be finalized in the upcoming weeks
Rock Tech's goal is to be the world's first closed loop lithium company
Starting with responsible mining in accordance with the strict Canadian and international regulations to the operation of its conversion plant designed to refine feedstock and recycle lithium products
there are no other projects planned in Europe with the equipment and assets required to recycle lithium
making Rock Tech uniquely positioned in this area
A certified external assessment2 forecasts the conversion plant's CO2 emission levels for the production of one tonne of lithium hydroxide to be 30% lower than the industry average
With current plant design and under use of only renewable energy sources carbon emissions could see a 60% reduction by 2026
the Company plans to utilize 95% of by-products and production residues
Together with the German Lithium Institute ITEL
Rock Tech is working on solutions for this with partners from the construction materials and waste management industries
Upon the commencement of battery-grade production
a leading provider of sustainable supply chain traceability
will provide a full-scale solution for supply chain transparency
Circulor's blockchain powered tracking will enable Rock Tech to comply with the European Battery Regulation's requirements and battery passport initiatives
has significantly increased the attractiveness of the North American EV and battery market
With engineering for the Guben converter nearing completion
the Company is now starting planning for its next converter project
Rock Tech is therefore pleased to inform that it is in the final process of identifying suitable locations in the northern United States and Ontario
More details will be announced once the final site selection has been completed
The raw materials mined at Georgia Lake are a key ingredient for Rock Tech's integrated strategy
The Georgia Lake project contains over 40% of the published Mineral Resources in the Thunder Bay District and the newly added Boston Lake mining claims offer another opportunity to further expand
the Georgia Lake project has advanced significantly
The 2023 winter drilling program has been finalized with positive results
and an extensive summer exploration program is focusing on prospecting
mapping and trenching3 (see press release of Rock Tech dated 04 July 2023)
The Company intends to extend the life of mine and the Mineral Resource considerably from 2023 to 2024 through a series of phased exploration programs and move the project into construction next year
The Company maintains good relations and information exchange with all relevant stakeholders
CIBC is serving as Rock Tech's strategic advisor that manages a structured process intended to identify partners for the development and further exploration of the mine project

The approved investments will be in the form of equipment that will affect all of the processes at the Guben site
Interiors, Industrial, Medical/Hygiene
Trevira’s owner Indorama Ventures has approved various large projects at the Guben site
which will be “of enormous importance” for the entire company
according to Trevira’s CEO Klaus Holz
“These investments are an extremely important signal
They are a reiteration of the long-term commitment of our parent company IVL to Trevira,” he said
The approved investments will be in the form of equipment that will affect all of the processes (polycondensation
and textile processing) at the Guben site where Trevira produces filament specialties for the textiles industry
A total sum of around EUR 7.5 million is scheduled to be invested
These investments will generate additional quantitative growth and optimise processes and procedures at Trevira’s site in Guben where flat and texturised filament yarns are produced for automotive interiors
“We are very excited about the investments in the new equipment
The Guben site and the Filament BU will be strengthened by these projects,” said Edo Lieven
Trevira is a European manufacturer of high-value branded fibres and filament yarns for technical applications and hygiene products
automotive interiors and functional apparel
Two production sites and a Marketing and Sales office with a total of around 1,100 employees are located in Germany
These are supported by an international marketing and sales organisation
The head office of the company is located in Bobingen
Trevira has a reputation for fibres and yarns for flame retardant polyester home textiles (Trevira CS)
for its fibre specialties for hygiene products and technical applications
as well as for low-pill fibres for functional apparel

Trevira proves sustainable in different ways
A lithium factory is also being built in Guben
which will be used to produce lithium hydroxide

This could change once the first lithium factory in Europe has been built. Planned by Canada-based Rock Tech Lithium Inc., the construction project aims to set new sustainability standards. The company claims that it will be the first lithium hydroxide converter of its kind
With operations in both Germany and Canada
the company’s goal is to supply the automotive industry with lithium hydroxide in about two years
This substance is required to manufacture EV batteries
for which it is conditioned and finished in converters
A fair share of the lithium needed is to be sourced from Georgia Lake in Canada
Rock Tech envisages establishing five sites in Germany
Company headquarters are located in Vancouver
with two additional approvals to follow before the end of the year
Rock Tech states that the construction project will draw a total investment of approximately 500 million euros
An initial lifetime of 25 years and a workforce of 160 are projected
annual production is expected to total 24,000 metric tons
enough lithium hydroxide to power 500,000 EVs in Europe
Brandenburg State Minister for Economic Affairs
feels the construction of the converter is important for both Brandenburg and Europe:
we are strengthening our position as a future EV hub in Europe
Brandenburg will be home to the entire value-added chain
from raw material processing and battery and cell production to EV manufacturing and battery recycling
The Commission claims that it is thus all the more important for Europe to ensure security of supply
as this would make the energy and mobility transition in the EU more autonomous
But can the planned Guben facility do more than reduce dependence on imports by covering the entire value-added chain
Rock Tech underscores that sustainability and environmental compatibility took centre stage from the word go
The company intends to run the plant on renewable energy
The company further states that, in addition, one of the main objectives is to establish a closed market cycle
as lithium is becoming an increasingly scarce commodity
This is why Rock Tech wants to integrate lithium recycling in the value-added chain
The concept involves reconditioning the lithium once the batteries have reached the end of their service lives and then using the raw material all over again
According to Rock Tech Inc Spokesperson Wolfgang Böhm
this is the backdrop against which the facility will be constantly refined and upgraded
Another goal is to use about 50 percent recycled raw materials by 2030
This would reduce the need to mine new lithium
a paltry one percent of all lithium used worldwide is currently recycled
Furthermore, the company announced in March 2022 that it will join forces with the Fraunhof Institute for Environmental, Safety and Energy Technology UMSICHT and Circulor Ltd
Rock Tech expects these partners to be of assistance in optimising processes that are already in planning and in reducing energy consumption
both lithium and carbon dioxide emissions at Rock Tech will be tracked for Rock Tech from the very beginning of the value chain
Buyers of the lithium hydroxide will be able to access information on the source and environmental footprint of the commodity – in real time to boot
what is precipitated in the chemical reaction as a by-product in addition to gypsum
sodium sulphate and zero-liquid discharge (ZLD) is mostly aluminium oxide silicate (260,000 metric tons per year)
This substance is especially well suited to construction
a sector in which Rock Tech is already looking for potential buyers
Until further notice, the raw material will continue to be imported from Canada and elsewhere. However, resorting to local resources is an option that cannot be ruled out. This is why the company is intent on reducing its environmental footprint as quickly as possible, says Böhm. After all, lithium mining is harmful to the environment. As reported in the en:former
conventional lithium mining produces carbon dioxide emissions and consumes a lot of water
The latter holds true not least for regions which are plagued by water shortage
Wolfgang Böhm further states that the company is generally interested in drawing on local resources, above all given that several reserves have been discovered in Germany. For instance, as reported by the en:former
the Ore Mountains in Saxony contain an estimated 125,000 metric tons of lithium metal
enough to manufacture several million electric vehicles
local mining would be permitted pursuant to European regulations and environmental standards
This would result in improved environmental compatibility and increased sustainability
We encounter energy everywhere – at home, on the street, in the office and on the workbench. But what exactly is energy? How and from what is it made? How is it stored, transported and converted?

With the popularity of the now ubiquitous Body Worlds exhibits touring the world with their skinned and exploded figures in motion
it is little wonder that the inventor of the technique that made those displays possible would start his very own scientific house of gore
Located in the city of Guben, Germany
after being run off from previously planned sites for their museum-lab
the Plastinarium presents the process and results of a controversial embalming process developed by one Dr
The process involves removing most of the water from a corpse's dead tissue and replacing it with synthetic polymers that preserve the bodies in perpetuity as medical models and items of curiosity
This is usually done once the subject has had their skin taken away
Von Hagens collects his specimens from body donors who sign a contract allowing him to plastinate their bodies after their deaths
The Plastinarium allows visitors to walk through the steps of the gruesome
but fascinating process as they tour the actual lab where the preservation is taking place
provides ample room for both process and display
and there is no shortage of pieces in the museum
but there are also a number of humans who are said to have voluntarily donated their bodies to the procedure
The center supplies the touring Body Worlds exhibits with new displays and provides upkeep for their existing ones
but anyone wanting to see how the bodies get made can now come right to the source.

more private reconfiguration: Dormant forklifts dot the courtyard next to bits of fencing and piled rebar; water drips from 20-foot ceilings in the dormitories; floral wallpaper sags off yellowed plaster
- 74 Things Every Great Star Wars Movie Needs
This wilted splendor gives way
to the fundamental work of von Hagens' business—the extraction of body parts and sale of preserved remains
he spent $50 million to turn this run-down site into a global headquarters for his Body Worlds exhibits
fitted out with tanks of acetone (for defatting tissue)

But it could just as soon have been frozen whole and sliced into millimeter-thick sheets
these could end up in lecture halls or museum displays
or added to an archive in the rooms upstairs
where parts of animals and people are kept in bins marked brain and foot and scrotum
The 68-year-old scientist who runs this factory of desiccation and dissection spends his days shuffling through its corridors with his lapdog

while his body has been exploded into parts that hang from a rack on fishing lines
their flesh corroded to reveal clouds of blood vessels
and yaks and pigs with their ribs spread out like wings
Von Hagens calls the place his Plastinarium
It's the first permanent display of specimens from his stupendously successful traveling exhibition of flesh preserved with plastic
and scores of other cities since the 1990s; it has inspired copycats and lawsuits and sold more than 35 million tickets
As a young lecturer at the University of Heidelberg in 1977
von Hagens developed a laboratory trick that at first seemed of interest only to a dwindling cadre of macroscopic anatomists: a way to impregnate slices of kidney tissue with plastic
Soon he'd made the process work for whole dissected bodies
He starts with regular embalming—the injection of formaldehyde into femoral arteries—and then submerges the body in acetone
After that he drops the corpse into a basin filled with liquid polymer
where the acetone bubbles off as plastic pushes in to take its place
but eventually von Hagens figured out a way to turn his method into a morbid empire
devoted to the processing of animal and human cadavers
the complex in Guben employed 220 people and churned out specimens for exhibition
along with those that could be sold to medical schools around the world—limbs and joints for orthopedics
and $75,000 plastic-filled corpses for gross anatomy
and entrepreneur stood at the center of his factory
The business that he'd worked so hard to build was crumbling
Revenue from Body Worlds had begun to taper off
and sales of body parts to universities had always been propped up by the exhibits
His plastination plant in China was nearly defunct
and his would-be partnership in Siberia had ended in a scandal
the operation had gotten to the verge of bankruptcy
von Hagens said; two-thirds of his employees would be let go
he'd been diagnosed with Parkinson's disease
no way to prevent his brain from shrinking
von Hagens' limbs will get more rigid and his face more like a mask
After a career spent staving off rot and giving life to stiffened corpses
Vincent FournierMany people expire without a warning; others learn they have just days or weeks to live
Von Hagens' end has been forecast at least three times already
Growing up the middle of five children in the midsize East German town
he learned in grade school that he had a dangerous bleeding disorder
("I felt sorry for my parents," he recalls.) The bleeding put him in the hospital on more than one occasion
but now he keeps it in check by eating peanuts
it seems a major pitfall for a professional dissector who works with sharp tools
and I can't help but worry when von Hagens emerges from his suite of rooms in Guben on the morning of my visit
It's been nearly six months since he gave his good-bye speech
and the Parkinson's has left his face both slack and stiff: He has a drooping jaw and arching eyebrows
as if frozen in a moment of profound dismay
von Hagens now has trouble finishing a sentence
His illness comes in waves that start at his fingertips and work their way up to his throat
until they churn his words in a quicksand of slurs and stutters
"I hope for a successful therapy for Parkinson's!" he bellows at one point
and then explains it's easiest for him to speak in sudden outbursts
"Don't be afraid!" he shouts
though it would seem more apropos to creep around the place at night like Scooby-Doo
tiptoeing past the potted ficus trees—also plastic
This time a doctor colleague gave the sentence: He had an unusual condition that could reduce the flow of blood through his aorta and kill him off before the age of 45
von Hagens knew that the heart is poorly engineered—the layout of the coronary arteries leaves it prone to blockage
The timescale of this second diagnosis was long enough that he could ignore it
(It turned out his colleague had been mistaken.)
As we make our way through the anatomical museum
von Hagens lists some other body parts that are not so well designed
There are major problems with the penis—the prostate gland should not be wrapped so tight around the urethra—and he has a lot to say on the weakness of the knee
But von Hagens doesn't stint on praise for human evolution; he admires many of our features for their complexity and cleverness
mortal diagnosis—an illness of his mind this time
not of his heart; one bound to mangle up that perfect blueprint until it deprives him of his ability to walk and talk and eat and think
He knows his Parkinson's cannot be wished away or cured by eating peanuts
"I am a doctor," he told his friend Stephan Rathgeb
"I give myself seven more years."
the doctor hopes to live as long as most people
(He used to say he'd make it to 100.) And the illness hasn't sapped his drive to cut up corpses
Though he tires easily and his hands have grown too shaky for a scalpel
von Hagens still makes his rounds through the Plastinarium in his trademark zippered vest and black hat
looking over assistants' shoulders and spitting out instructions
he circles around a female corpse with dyed brown hair
Though the skinless specimens on display can look like plastic toys
this one—still somewhat fresh—looks like someone's aunt or sister
an assistant mists the body with a water bottle so it won't dry out
Two or three corpses arrive in Guben every week—all come from willing donors—and this is where they're arranged and posed
while some are frozen solid at minus-94 degrees Fahrenheit for passing through the band saw
There's a human leg on a rack with the genitals still attached
as if a man's lower half had been split like a wishbone
a set of hard-edged blocks that look like cubes of fatty cold cut or chunks of schweinebraten
They're one of von Hagens' new inventions: a teaching tool for medical students—when stacked together on matching faces
The obese woman will be cut in horizontal sections
A red laser line shows von Hagens' assistants where to place the blade
Watching him at work invites a simple question
one so obvious and yet so personal that at first it's difficult to ask
What will happen when the Parkinson's has run its course
with metal pins stuck into his face and his feet propped up on blocks of foam
Will someone do to him exactly what he's done to her
Vincent FournierDead and dying bodies have
"The natural processes of corruption and decay have become disgusting," wrote the aptly named British anthropologist Geoffrey Gorer in his 1955 essay "The Pornography of Death." In the 1800s
children and adults alike were routinely confronted with mortality—dead relatives were washed and laid out at home
novelists were preoccupied with deathbed scenes of melancholy
Now such encounters are rare and our experience of death—our engagement with it as a fact and force of nature—has been replaced by a kind of prudery
"If we dislike the modern pornography of death," Gorer wrote
referring to the gangster movies and horror comics of his time
"then we must give back to death—natural death—its parade and publicity."
where dissected heads hang shameless from the walls
Gorer's plea has finally been granted
However else one might describe the Body Worlds exhibits—as science or as flimflam—they have done more than any other modern spectacle to bring the human corpse into view
tens of millions of people in the developed world have had the chance to see cadavers on parade
to view the lifeless bodies of their fellow beings without the intermediation of fear or shame
von Hagens has refigured death for modern sensibilities
To see one doesn't make you sad or sick; it doesn't fill you with anxiety
The experience is something else instead—an encounter with a memento mori that's both dry and durable and can be split and peeled without disgust
It's death denuded of its most gruesome elements
When von Hagens shipped his first sturdy specimens to Tokyo in September 1995
he tapped into a form of entertainment that had been dormant for a century
expositions of anatomy were commonplace in the red-light districts of Europe and America
and casts of skin disease or venereal infection
The popular display of body parts—real and fake—arrived in the US in the 1840s and had largely faded out by the 1920s
was cleansed of its more salacious trappings and subsumed into the upright field of public health
the German Hygiene Museum in Dresden displayed its Glass Man—a Bauhaus-inspired life-size figurine with plastic skin
and painted wire for its veins and arteries
the Glass Man was the iPod of anatomy: an elegant
reproducible commodity that could be shipped around the world
the original and its copies turned up in Buffalo
it would later stand for Nazi racial pride
By the time the Glass Men marched across the continents
the public display of authentic bodies had all but disappeared
would not be back until von Hagens' first show in Tokyo in 1995—half a million people came to see it
Von Hagens' plastinates tapped into a latent fascination with corporeality
feeding corpses to vultures—attest to our need to take control of death and represent it for the living
Von Hagens rendered this ancient practice in a modern form
Plastination brought death into the light and gave it an aesthetic perfect for our scientific age
von Hagens seems less a doctor than a master plumber or mechanic
each corpse a set of tubes that must be filled with fluids of the right viscosity
when the plastination experiments grew too unwieldy for his lab in Heidelberg
The cluttered workshop is his natural habitat: He's most at home among barrels of chemicals and boxes of stray parts
Among his first tools was a deli meat slicer for cutting human kidneys into even slabs
Later he stretched bits of panty hose to strain out blood clots and plopped brains into pudding molds so they wouldn't get malformed
Von Hagens lives his life the way he works
without regard for custom or pretense and with a tendency to view his own body in mechanistic
To watch him eat is to see a man refuel a vehicle: He's made a habit of going for days on little more than a bowl of berries or a quart of milk
and when dining out he likes to order whichever dish will come out quickest
Each of his essential life functions has been assigned a place in the spartan four-room factory suite where he lives alone
a small area with exercise equipment in the middle
and then an office with a dine-in kitchen that's stocked with instant soup and crystallized coffee
A large institutional clock hangs from the wall
"The body is like a car or an engine," he says
He tried to flee from East Germany while in his early twenties but was captured by the Stasi and imprisoned for two years
he married a woman named Cornelia von Hagens and chose to appropriate her noble-sounding name
(His given name is Liebchen.) They had three children but the marriage soured when von Hagens' experiments with plastination drove the family into debt
and it fell apart when he started seeing someone else—a young woman in his dissection seminar named Andrea Whalley
and von Hagen married Whalley three years later
At times he was motivated by a simple need to outdo himself
spending $4 million and 65,000 hours of employee time—and building a warehouse-sized freezer—just to plastinate an elephant
That impulse hasn't faded with his health and business fortunes: Now he says he'd like to do the carcass of a blue whale
and then he'll make the body of a dinosaur from parts of other animals
those around him do the best they can to manage his expectations
In May of 2012 his son Rurik began managing the company in Guben
he's the one who shut down the facility in China and helped orchestrate the layoffs at the Plastinarium
It also falls to him to tell his dad what can and can't be accomplished
Though Rurik wears his hair slicked back and has a B-school tendency to wink while making a point
he can sound like a kid who only just discovered that his father is not a superhero
"For all his life he liked to have a certain degree of stress
because that's what kept him running and gave him ideas," Rurik says
von Hagens spent almost every waking hour in the lab
and in spare moments he would study foreign languages on flash cards or take power naps while sitting at his desk
"That really doesn't work anymore," Rurik says
"But that is how he lived for decades."
and then suddenly he is not efficient anymore
Vincent FournierThere was a time when the prospect of von Hagens' own dehydration and defatting was among his favorite topics
even many years ago," Angelina tells me while her husband takes a nap inside his modest suite
She is often on the road but has come to Guben to cohost my visit
"He's about 15 years older than I am
and statistically women live longer than men
and I would want you to plastinate me.'"
He calmed me down: 'You wouldn't have to do it immediately—you could put me in the freezer
but not more than one year because then I'd get those freezer burns.'"
Angelina has taken on the role of company spokesperson since soon after her husband got sick
and she prepares her thoughts behind pursed lips and eyelashes battered with mascara
Angelina watches over her husband from a kind of lupine crouch
bounding in when his voice begins to falter or when he starts to stray off message
and she'll fill the silence with a sound bite
one of many predigested phrases from his past: The more you think about death
Or: Everyone dies a double death—a death of your soul and a death of your body
Then he'll turn to me with resignation in his eyes—a sheepish
doleful look—and nod: "My opinions are identical with hers."
on the matter of his death and plastination
He no longer comforts her with talk of the freezer
and she's not at all resigned to carry out his final wishes
The squabble reemerges when the three of us are touring through his private workshop—a brick-floored space that serves as a makeshift gallery for his latest work
Here's where he keeps his silver-plated cow heart; a table made from giraffe legs wearing glitzy
high-heeled shoes; and skinny slices of a bookshelf
Von Hagens wants to be slivered into sections too
That way his body can be displayed in different places at the same time
he'd planned to plastinate his father and pose the corpse as a patient on a table
then later have his corpse posed beside it
tending to his garden and raising chickens.) Angelina
would rather keep him as a plastinated whole
Von Hagens answers first: "My opinion is ..
"And I've postponed these thoughts," she says in turn
Von Hagens peers at her from beneath his leather hat and tries to speak again
At last he finds the strength to force out: "It's a strange subject!"
Bella the dog scampers ahead and across the courtyard to a room where the ceiling is partially caved in and plants
Then she circles back to von Hagens and sniffs around his ankles
When she gets excited or upset—at the sight of a plastinated baby chick
or a bucket full of bones—he scoops her up and murmurs into her ears
you know," he says when we get back into his office and the dog has settled in his lap
His voice grows weak—from disease or emotion
He's been talking coolly about what it means to die and what might happen to his corpse
but it's the topic of his dog that chokes him up
"She can always sit beside me," he sputters
and then pinches the bridge of his nose between his fingers and begins to weep
We sit in silence while his shoulders shake
grief and sorrow are no different from any other defect of the human body that should be amenable to fixing
he blames them on his disease—a condition I later learn is called pseudobulbar affect
or the involuntary and inappropriate expression of feeling
before he started treatment: "I was very upset at my uncontrolled emotions
I could not even go to the cinema." He takes off his hat and shows the lumps on his scalp where the leads from brain-stimulating electrodes have irritated the skin
It's the only time I've seen his naked head
He says that he's been better since the treatment
"Just now is the first time for the last week that I cried
von Hagens had revealed another of his works in progress
a gruesome scene he calls "Headless Into Death." So far it consists of a smashed-up
'80s-model Volkswagen with a dirty American flag spread across the seat
the owner of the car committed suicide by driving headlong into a tree
and now he plans to put a section of the driver's headless body in the front seat
The dead wife has already been processed here in Guben
waiting for her husband as a full-body plastinate in silicone
it sounds as if he's playing out a fantasy with dolls
a diorama of how he might like to die himself
revving till the very end—not puttering with Parkinson's
one thing is clear: They won't have a chance to argue
Donors to the plastination program sign away their right to say how their bodies might be posed
(The consent form does ask if they agree to be "exhibited in public" or "interpreted as anatomical works of art," but it also says their answers to these questions are "recommendations rather than binding terms.") Von Hagens can arrange his corpses in a mock coitus or cast a mold of them to make an ersatz Jesus Christ—both of these are on display in Guben—or he can carve them up and ship the parts for use in classrooms
Many have been willing to supply their flesh
The business staffs a body hotline and the deceased save the cost of interment or cremation
Angelina says they've had to make a waiting list for would-be plastinates
She also tells me that of the people who have enrolled
just one in 10 gives ideas for how they'd like their bodies shown
to leave their fate in von Hagens' hands
Perhaps they feel the standard rituals of death are not for them
They've chosen to be anointed with acetone and polymer and sliced for public view instead
newfangled rite has been von Hagens' task for almost 30 years
and he has lived his life the way he treats his bodies—as something manufactured that can be tinkered with to suit his needs
This may be the doctor's final lesson: When he dies
he will be plastinated—that much is certain—but the posing of his body will not be up to him
he'll leave the mastery of life and death to someone else
"Understanding how the world works is a gift for me," he says
There's something more he wants to say
a red light goes on," he mumbles at last
