Towards a business case for CO2 mineralisation in the cement industry

The cement industry is responsible for approximately 7% of anthropogenic CO2 equivalent (CO2e) emissions and has the highest carbon intensity of any industry per unit of revenue. This paper uses integrated techno-economic modeling to demonstrate that CO2 mineralization of silicate minerals can reduce CO2e emissions by 8–33% while generating additional profit of up to €32 per tonne of cement. Two key conditions for positive business cases are the use of resulting products as supplementary materials in cement blends and eligibility for emission certificates.
