Circular concrete.
Low-carbon construction materials, upcycled from end-of-life concrete
The construction materials challenge
Every year, the world produces ca. 4 billion tons of cement, accounting for 8 % of global CO₂ emissions. Simultaneously, 3 billion tons of concrete waste are downcycled or discarded.
Upcycling to decarbonize concrete
everox transforms waste concrete into high-quality drop-in substitutes for cement, aggregates and sand. Unlocking the value of concrete waste to decarbonize new concrete while enabling a global transition towards a local, circular, and sustainable production of building materials.
everox sustainable vision and mission
We envision to reduce global CO₂ emissions by 2% by phasing out the use of virgin materials in concrete via the patented everox waste concrete upcycling process.
Concrete waste upcycling with the patented everox process
The concrete industry is at a breaking point. For decades, its linear “take-make-waste” model – extracting raw materials, manufacturing products, and discarding them – has remained unchanged, along with its environmental impacts.
“We believe it’s time for a fundamental shift in the concrete industry, from extractive to fully circular.”
Thomas Petithuguenin, everox CEO
Our process transforms end‑of‑life concrete into four high‑value drop-in substitutes for cement:
Activated Cement Paste
ACP is a reactive SCM produced from concrete waste by everox upcycling technology.
Recycled Coarse Aggregates
RCA is a clean, high-performance aggregate suitable for structural and non-structural concrete applications.
Recycled Fine Aggregates
RFA is a clean fine aggregate free from harmful contaminants.
Fine Inert Filler
FIF is a quartz-rich material composed of fine particles smaller than 0.25 mm.
The game changer: Activated Cement Paste as a sustainable SCM
In traditional recycling processes, cement paste is treated as waste and is therefore lost. But this materials holds immense value. By recovering and reactivating the cement paste trapped in concrete, everox can replace up to 30 % of new cement, drastically reducing the carbon footprint of new concrete mixes.
How to reduce CO2 footprints with Activated Cement Paste as a novel SCM
How can concrete fines become a profit driver while reducing the carbon footprint? everox Activated Cement Paste can lower cement demand, cut CO2 emissions, and enable resilient local supply chains – all at the same time.
The everox Garden: Research-driven, reliable equipment, and new material standards
At everox, fact over fiction guides everything we do.
We validate our results conscientiously by in-house testing and independent third-party verification, because real progress demands real proof. That commitment led us to create the everox Garden: a unique space where innovation grows from the ground up.
Material certification in progress
everox is pioneering the establishment of new material standards for the industry. Although the certification pathway for novel Supplementary Cementitious Materials (SCMs) is complex, our four innovative materials are already advancing through EU-standard recognition and national approval processes in the Netherlands. In parallel, everox is pursuing a European Technical Assessment (ETA), which will enable rapid CE certification across all EU member states, ensuring reliable, compliant, and future-proof performance for our partners.
