As our cities grow and we build the equivalent of New York City every month
we need to make space for new buildings by demolishing the old ones
This generates billions of tons of construction demolition materials (CDM) each year
Recovering CDM to build new from old is essential to create a circular economy that preserves primary resources and accelerates the shift towards a net-zero built environment
circularity is at the core of everything we do
and we aim to turn every metropolitan area where we operate into a recycling hub
and we're on track to recycle 10 million tons per annum
To achieve this, Holcim is creating a network of CDM recycling centers across Europe. One of these sites, Recycling Center Ostschweiz (RCO) in Niederstetten
Switzerland - which we operate through a joint venture with Zürcher Kies und Transport AG - opened its doors in May 2021
and is making a significant contribution to sustainable
This 20,000m2 site is unique in Eastern Switzerland
crush and reuse contaminated mineral excavation and demolition waste.
digitization and highly automated processes
it produces a wide range of recyclable building materials for the regional market that match primary products in quality and aesthetics
RCO processes unpolluted mineral excavation and demolition materials using a dry mechanical process
we can recycle additional materials that would otherwise be sent to landfill
track ballast and excavated materials – both contaminated and contaminated
The fully automated process involves two innovative twin-shaft crushers
sand processing and material storage in a silo
Rainwater is treated in a circuit and fed in as washing water
with the resulting fine materials de-watered in a filter press
RCO can recycle around 200,000 tons of material every year to produce high-quality
sustainable building materials – gravel or mixed granules for use in everything from certified concrete or certified aggregates
That’s enough to build over 500 single-family houses entirely from recycled material
and the aggregates can even be used to produce concrete at Holcim’s nearby plant in Niederstetten
Using our proprietary ECOCycle® technology we can build cities from cities
upcycling up to 100% of CDM into new solutions thanks to Holcim’s proprietary advanced processing technology so resources get reused and nothing is lost
This reduces waste sent to landfill and our dependence on primary materials
grind and recycle construction demolition materials into new building solutions with no performance compromises
we will have over 150 ECOCycle® platforms in operation in Europe alone
According to Switzerland’s Waste Ordinance
mineral construction waste should be sorted and recycled as far as possible into secondary raw materials
and RCO is making a significant contribution to sustainability and circularity efforts in its region
committed to recycling mineral construction waste and using it as construction material in order to achieve the sustainable closure of material cycles
By recycling a wide range of polluted and unpolluted material
RCO helps the canton save landfill space and natural gravel resources
The Niederstetten site is also home to RCO’s new company building constructed entirely from recycled building materials
this serves as a showroom to show customers and the public all of the advantages of sustainable and circular building materials
state-of-the-art facility is designed to take in a greater variety of waste material than most other processing centers and close the material loop by almost 100%.
In Switzerland, we are rolling out circular construction at our cement plants and continuing to grow in this space through M&A, with four European acquisitions in 2024 to date, one of which, Cand-Landi
