Germany: Climatetech startup Co-reactive has closed a €6.5m seed funding round led by private equity firm High Tech Gründerfonds (HTGF), with additional support from public programmes, including the Federal Funding for Industry and Climate (BIK) of the German Federal Ministry for Economic Affairs and Energy. Founded in 2024, Co-reactive is developing a continuous CO₂ mineralisation process that converts captured CO₂ and minerals such as olivine and metallurgical slags into CO₂-negative supplementary cementitious materials. The technology is designed as a drop-in solution for existing cement and construction materials plants. With the financing, the company plans to scale to a continuous demonstration plant with a capacity of about 1000t/yr by the second quarter of 2026, and is preparing ‘first-of-a-kind’ industrial plants at the >10,000t scale from 2027, which will mineralise CO₂ directly at cement and steel production sites.
