Catch4climate project completes construction of 60m preheater tower

Scherr+Klimke AG build 60m Catch4climate

preheater tower in Germany

A new milestone for the pilot project "Catch4climate" has been achieved with the completion of the 60m-high preheater tower.

A demonstration plant is currently being built on the site of Schwenk Zement's Mergelstetten cement plant in southern Germany, which will use the thyssenkrupp polysius^® pure Oxyfuel process for CO₂ capture and is scheduled to go into operation at the end of 2024.

The polysius^® pure oxyfuel process is a clinker firing process in which pure oxygen is introduced into the cement kiln instead of air. This significantly increases the CO₂ capture potential.

"Catch4climate", for which the four cement manufacturers Buzzi SpA, Heidelberg Materials AG, Schwenk Zement GmbH & Co KG and Vicat SA have joined forces, is actively tackling the capture of CO₂ and its industrial use.
