Innovation on the activation of clay without calcination

Polysius Green Cement small

Schwenk Zement and thyssenkrupp Polysius jointly developed an innovative technology for the activation of clay, to reduce the CO2 in the global cement and concrete production. The meca-clay technology enables the activation of all types of clay using only electrical energy instead of fossil fuels. It is based on the booster mill technology from Polysius with a mechano-chemical activation, which is used in Schwenk’s Celitement. A first demonstration unit will be installed in Schwenk’s Allmendingen cement plant and be commissioned in 2025.
