Building materials manufacturer HeidelbergCement is advancing in the development of CO2 separation technologies to help reduce its carbon emissions.
To help achieve its goals, the company is starting further development and scale-up of the Low Emissions Intensity Lime and Cement (LEILAC) technology together with Australian technology company Calix and a European consortium.
The LEILAC process makes it possible to capture high-purity CO2 from cement production via a separate exhaust gas stream and to utilise it for other purposes.
Two-thirds of CO2 emissions of a cement plant are process-related emissions generated during the heating of limestone and are therefore unavoidable.
