60-metre milestone in the catch4climate pilot project

Preheater tower completed

Our catch4climate project is making great progress. In March 2024, we installed the kiln as central part of the plant with millimetre precision and quite some heavy lifting. The project is realised in a consortium with the goal to build and operate a demonstration plant on a semi-industrial scale.

At our Mergelstetten cement plant, Germany, the polysius® pure oxyfuel technology will be applied to capture and reuse up to 100 % of the plant’s CO₂ emissions. Since carbon is urgently needed in many industries, for example in the production of fertilisers, fuel for long-haul flights, or sanitary medical products, the captured CO₂ can be utilised for a variety of purposes.

Construction progress on the catch4climate research project. The four cement manufacturers Buzzi SpA - Dyckerhoff, Heidelberg Materials, SCHWENK Zement and Vicat joined forces in a research company in 2019 to realise the CO₂ capture project "catch4climate".

Construction progress on the catch4climate research project. For the "catch4climate" research project, the pure oxyfuel process for CO₂ separation is being used for the first time. A dedicated rotary kiln line is being built for this purpose, which will be used exclusively for research and development.
