If the cement industry were a country, it would rank as the third-largest emitter of greenhouse gases, accounting for 8% of global emissions, following China and the USA. The cement production process releases substantial CO2 from limestone, highlighting the urgent need for solutions to harness and utilize these vast quantities of CO2. This is where Co-reactive steps in – a spin-off from RWTH Aachen University. We're developing an innovative process for CO2 mineralization, binding CO2 in solid form. This groundbreaking technology converts CO2 into solid carbonate that can be used as a sustainable resource. By incorporating our product into construction industry, we not only dramatically reduce the carbon footprint but also enhance the properties of construction material.
