Carbon capture for the cement industry Result In Brief

Cement production contributes globally with 6-7% of anthropogenic CO2 emissions. CO2 generation is an inherent part of the cement production process through the calcination of limestone (CaCO3 converted to CaO and CO2). Retrofitting CO2 capture to existing cement plants is the most viable option for significant emissions cuts in the cement industry.
