A ground breaking ceremony has been held at Holcim’s cement factory in Lägerdorf, Germany, where the company is deploying its Carbon2Business project.

The project aims to capture more than 1.2 MtCO2/y with the captured CO2 due to be repurposed as an industrial raw material, and from 2029 cement production at Lägerdorf will be entirely net-zero. CO2 will be captured from the cement manufacturing process using Thyssenkrupp’s oxyfuel technology, which separates CO2 from the exhaust gases of cement factories in a kiln system.

Pure oxygen is used in the combustion process instead of ambient air, allowing almost 100% of the emissions from cement clinker production to be captured.
