Germany: Cemex Zement has announced the start of carbon-neutral building materials development at its 1.9Mt/yr Rüdersdorf, Brandenburg cement plant. Called Vision Rüdersdorf, the project consists of, “the comprehensive investigation of various approaches to breakthrough technologies in order to prevent process-related carbon dioxide (CO₂) from entering the atmosphere, but to use it for beneficial purposes. The investigation areas can be divided into capture, storage or use of CO₂. This will help towards Cemex’s target of 55% CO₂ emissions reduction across Europe by 2030 and its commitment to deliver carbon-neutral concrete by 2050.

Chief executive officer (CEO) Rüdiger Kuhn said, “For years, sustainable success has been achieved here in the reduction of fossil fuels and in the selection of alternative recipe ingredients for cement. The experienced team is always looking for possible improvements. When it came to determining the best possible CO₂ emission values, the Rüdersdorf plant was always at the forefront of the European cement industry and has thus also earned an excellent reputation in the global Cemex organisation.”

In order to realise Vision Rüdersdorf, the producer has partnered with companies from other industries. Managing director and plant manager Stefan Schmorleiz said, “In an interesting approach, the CO₂ that we capture is used as a raw material for downstream processes in the chemical industry. Another approach is to innovate in the storage of CO₂. With these efforts, and our commitment to review and invest in these technologies, Cemex Zement is making a contribution to the decarbonisation of the cement industry.”
