University of Strathclyde spinout Ureaka is moving its carbon-negative supplementary cementitious material (SCM) technology toward commercial use. The process takes calcium and silica from waste streams like demolished concrete and reacts them with captured CO2 to create a cement replacement. This permanently mineralizes the CO2 while producing a material that can be used in existing concrete production systems. The company has support from the Industrial Biotechnology Innovation Centre's Spin Out Fund and is now moving beyond lab work into factory-scale modeling and third-party testing. Ureaka is also seeking additional grants and preparing a seed investment round to scale the technology further.
