Waste concrete holds stranded mineral value.
Every year, large volumes of concrete are demolished, crushed and downcycled. The cement-rich fine fraction still contains valuable calcium- and silica-bearing minerals – the building blocks of new cementitious materials.
Ureaka sees this not as waste, but as an abundant feedstock for low-carbon cement replacement.
How Ureaka turns waste concrete into cement replacement
We recover mineral value from waste concrete fines, combine it with CO₂ mineralisation, and produce a carbon storing supplementary cementitious material.

Drop-in pathway for lower-carbon concrete
Why the Economics Can Work
Most low-carbon cement technologies struggle because they add cost. Ureaka is designed around low-value feedstocks, low-energy processing and circular reagent use.
A pathway to carbon-negative cement replacement without a green premium.
Innovators at Work
Ureaka is led by a team with deep experience across carbon capture, cement chemistry, mineral processing and sustainable construction. Together, they are developing a practical route to turn waste concrete into valuable low carbon cement materials.
