## About Co-reactive

Co-reactive is a climate-tech startup based in Düsseldorf, Germany, founded in 2024.

The company specializes in carbon mineralization technology, which transforms captured CO2 into high-performance, CO2-negative Supplementary Cementitious Materials (SCMs) for the construction industry. Co-reactive aims to decarbonize the high-volume construction sector by providing sustainable alternatives to traditional cement. The company’s innovative process permanently binds CO2 within construction materials, enhancing their strength and durability while significantly reducing the industry's carbon footprint. Co-reactive has established a 1,000-ton demonstration plant in Erkrath to produce these CO2-binding cement substitutes and is focused on scaling its technology for industrial applications. With €6.5 million in seed funding and recognition from the EIC Accelerator program, Co-reactive is well-positioned to support cement and concrete manufacturers in their pursuit of sustainability.
