  • Project Description

    The joint project “C²inCO2” addresses an alternative approach to CO2 utilization based on the mineralization of fines from concrete recycling and their use in the large-scale production of novel cements and concretes. Re-integrate the CO2 released during calcination into limestone and to use it as a building material significantly reduces CO2-emissions from the cement and concrete industry.
