BTU students visit CEMEX: insights into the future of cement!

Around 40 students from BTU Cottbus-Senftenberg visited the cement manufacturer CEMEX at the production site in Rüdersdorf near Berlin at the end of May 2025. This excursion was organized by the Department of Decarbonization and Transformation of Industry (DTI), as part of the “Communication of Science and Technology” module. The students dealt intensively with the German cement industry, its challenges and opportunities for decarbonization and sustainable transformation.

A central goal of the excursion was to give participants a deeper insight into the cement manufacturing processes. The students had the opportunity to speak directly with industry professionals and gain valuable first-hand information. Additionally, they worked to develop science communication videos and group presentations for different audiences.

Focus on decarbonization

The module focused on combating the climate crisis through the cement industry. This faces the challenge of significantly reducing its CO₂ emissions. CEMEX follows a strategic approach. According to the company website, CEMEX relies on the use of alternative fuels to reduce dependence on fossil fuels.

Not only do alternative fuels provide an environmentally friendly source of energy, they can also help minimize the environmental impact of cement production. For example, biomass, often a by-product that usually ends up in landfills, is integrated into the production process. Not only does this help avoid greenhouse gases produced when waste decomposes, but it also contributes to the circular economy by reducing waste materials being sent to landfill.

In addition, residues from other manufacturing processes, such as slag, are also used in the cement plants. This not only promotes resource conservation, but also shows the industry's innovative approach to waste products.

Climate protection and transformation

CEMEX and similar companies are faced with the need to find new ways to reduce their environmental impact. The company has several initiatives to decarbonize its production methods and incorporate sustainable practices in cement production. These comprehensive measures contribute to the reduction of pollutant emissions and the positive transformation of the industry.

The excursion was a valuable opportunity for the students to gain practical experience. The collected video and audio materials are used to further develop their projects and thus make the knowledge about the cement industry and its challenges accessible to a broader public.

The information about the cement industry and its impact on the environment is of great importance. According to that Federal Environment Agency The industry in Germany is a significant CO₂ emitter, and a change in production methods is essential to achieve climate goals.

In summary, the excursion provided an excellent platform to discuss and understand critical issues such as sustainability and innovation in the cement industry. The gap between science and practice was successfully bridged here.
