Germany: Rohrdorfer has inaugurated a new pilot plant for tempered clays at its Rohrdorf cement facility in a ceremony attended by regional and state officials. They included Parliamentary State Secretary to the Federal Ministry of the Interior Daniela Ludwig, who cut the ribbon alongside Rohrdorfer managing director Mike Edelmann.
The pilot plant has been operational since July 2025 and activates up to 50t/day of raw clay through thermal treatment. Tempered clays can replace clinker in cement, reportedly helping to cut emissions by around 30%, according to the company. The project is funded by the Federal Ministry for Economic Affairs and Climate Protection and the EU, and will receive up to €8.65m in funding.
Daniela Ludwig said “With this new plant, the Rohrdorf cement plant is once again proving that it is one of the most innovative companies in our region. Decarbonising the cement industry is a key task if Germany is to achieve its climate goals as planned.”
By the end of 2026, Rohrdorfer’s Net Zero Emission team will determine the optimal composition of raw clays and refine the thermal treatment process, paving the way for a large-scale facility capable of achieving up to 60% CO₂ reductions.
Mike Edelmann said “We’ve achieved a lot within our plants, but our influence ends at the factory gates. The lack of planning security regarding CO₂ transport and storage, uncompetitive electricity prices and an uncertain mining landscape are holding us back. We urgently need more support from policymakers if climate targets are to be met.”
