From the laboratory to the construction site: How Co-reactive from NRW is decarbonizing the construction industry
Decarbonizing the construction industry is one of the biggest challenges of industrial transformation. Since its founding in 2024, Co-reactive, a climate tech startup based in Erkrath with roots at RWTH Aachen University, has developed a solution. Using a chemical mineralization process, the company binds captured carbon dioxide with mineral raw materials or industrial by-products, converting them into a new generation of low-carbon cementitious additives (SCM). The result is CO-SCM, which stores CO₂ permanently while improving concrete's strength and durability. Additionally, this process can be integrated into existing cement and concrete production without requiring a fundamental conversion. Thus, the company meets the growing demand for alternative binders and the increasing climate protection requirements of the construction industry.
