SCHWENK Zement commissions thyssenkrupp Polysius to build a demonstration plant for the production of activated clay without calcination

• New clay activation process without calcination reduces CO2 footprint in clinker production by over 40%

• Demonstration plant being built at the SCHWENK plant in Allmendingen

• Commissioning is planned for 2025

SCHWENK Zement GmbH & Co. KG has commissioned thyssenkrupp Polysius to build a demonstration plant for the production of activated clay without calcination. After the planned commissioning in 2025, the CO2 emissions resulting from the production of cement containing clay will be significantly reduced. The new plant is based on an all-electric clay activation process jointly developed by thyssenkrupp Polysius and Schwenk Zement without calcination and without fuels.

Luc Rudowski, Head of Innovation at thyssenkrupp Polysius:

"The composite cement to beproduced with the newly developed meca-clay only emits around 350 kilograms of CO2 per tonne of cement. Compared to average conventional cement production, the CO2 footprint can be reduced by around 42 percent."
