Develops CO₂ mineralization technology, converting industrial CO₂ & minerals into carbon-negative SCMs for cement & concrete decarbonization.
Based in Düsseldorf, Germany, Co-reactive develops continuous CO2 mineralization technology that converts industrial emissions and minerals into carbon-negative supplementary cementitious materials for the global construction industry. The company currently operates a semi-continuous pilot reactor producing 10 tons annually, with plans to scale to a 1,000-ton demonstration plant by the second quarter of 2026 and a 10,000-ton commercial facility in 2027. By replacing carbon-intensive clinker in concrete production, the firm serves major cement manufacturers and recently won first place in an accelerator program hosted by Holcim. To support this expansion, the enterprise secured €6.5 million in seed funding in early 2026 through a financing round led by HTGF, with additional participation from NRW.Bank and HBG Ventures. Co-reactive was founded in 2024 as a technology spin-off from RWTH Aachen University by Andreas Bremen, Orlando Kleineberg, and Willi Peter.
