Cement producers need cheaper ways to cut clinker
○ Supply is Shrinking
European fly ash output has halved in a decade.
○ High Cost
Green premiums block adoption at scale.
○ Integration Challenges
New supply chains demand costly retrofits.
Ureaka was designed to solve all three.
Demolition waste is stranded mineral value.
Waste Concrete
Calcium
Silica
CO₂ Reaction
Every year, billions of tonnes of demolition concrete are treated as waste. But they hold valuable minerals calcium and silica: the building blocks of concrete. Ureaka sees not a waste stream, but a feedstock - abundant, cheap, and in every city on earth.
How Ureaka creates carbon-negative cement
Unlock minerals. React with CO₂. Regenerate reagents.
Waste Concrete
Recovered minerals
Carbon-negative binder
Demonstrating cement replacement performance
✓ 20% clinker replacement achieved
✓ 88% of control strength at 28 days
✓ Performance aligned with EN 450-1 requirements
Why the Economics Work
Most low-carbon cement technologies add cost through expensive feedstocks, energy-intensive processing, or complex supply chains.
Ureaka takes a different approach. We start with waste concrete, recover valuable minerals, regenerate reagents in a closed-loop process, and avoid high-temperature kiln operations.
This creates a pathway to carbon-negative cement materials without a green premium.
