60% CO2 reduction in the construction of the "EDGE Friedrichspark" in Berlin

Only 30 percent clinker and a carbon footprint reduced by around 60 percent - the innovative, clinker-efficient cement "naturecem65" (project title CEM X) is being used for the first time on a large scale in the major Berlin construction project EDGE Friedrichspark by project developer Edge and construction company Züblin. The sustainable cement and concrete from manufacturer Spenner will be controlled and closely monitored with the help of predictive software from the award-winning solid UNIT start-up alcemy. The project is thus setting new standards in the field of clinker efficiency and sustainability.

Climate-friendly concrete solutions on the rise

"With naturecem65, the widely available substitute limestone powder is used as a replacement for CO2-intensive cement clinker. This offers enormous potential for reducing emissions. It's great to see how more and more solutions for climate-friendly concretes are being developed and taken up by the players in the construction industry. Every tonne of CO2 that we reduce in concrete does not need to be taken into account in costly carbon capture processes," emphasizes Thomas Zawalski, Managing Director of solid UNIT Germany.

"At the beginning of the year, our cooperation partner Spenner received Europe's first building authority approval for this new cement for the Berlin and Erwitte plants. We are very pleased that it will be used directly in the Berlin construction project EDGE Friedrichspark by project developer Edge. This is an important milestone for our customer and for our predictive quality control," says Hoang Nguyen, Head of Communication & Sustainable Construction at alcemy.

Modern office quarter in Friedrichshain-Kreuzberg

A state-of-the-art office complex is being built on an area of 39,000 square meters in Friedrichshain-Kreuzberg. The project will further develop the previously underdeveloped district around Ostbahnhof. "By using naturecem, we are placing a clear focus on sustainability. Our collaboration with the Berlin start-up alcemy has already been successful in the past: the EDGE East Side project on Warschauer Strasse, which was completed in 2023, also used sustainable concrete that was controlled with the help of alcemy's software," explains Andreas Muschter, CEO at Edge DACH.

Expert knowledge and digital planning methods for sustainable construction methods

"The use of more sustainable construction methods, such as CO2-reduced cement, requires extensive specialist knowledge right from the planning phase. By integrating digital planning methods, architects and urban planners can achieve careful coordination that transforms previous interfaces between planning and construction into resilient interfaces," emphasizes Dr. Tillman Prinz, Federal Managing Director of the Federal Chamber of Architects and Climate Advisory Board member of solid UNIT.

solid UNIT: Network for climate-neutral construction

solid UNIT e.V., the network for climate-neutral construction with mineral building materials, is an association of representatives from the construction industry and the building materials industry as well as universities, research institutes, chambers and start-ups in the sector. The aim of solid UNIT is to disseminate knowledge about the climate protection potential of innovative solid construction even more widely. To this end, solid UNIT promotes dialog and cooperation between politics, science, planners, architects, start-ups and the public and shows what is already possible today with mineral building materials in terms of climate neutrality.
