The development of Reuse Brew is the culmination of a partnership between the Chair of Brewery and Beverage Technology at Technical University of Munich (TUM), the Chair of Urban Water Systems Engineering at TUM, the city of Weissenburg in Bavaria, and Xylem. This collaboration showcases the transformative potential of advanced water treatment technologies in producing a safe and palatable beer, promoting sustainable water management practices across Europe.

“Reuse Brew is not merely an exceptional beer; it exemplifies the vast capabilities of water recycling in combating the pressing issue of water scarcity,” said Roxana Marin-Simen de Redaelli, Vice President, Central Europe and Nordics at Xylem. “This project is a beacon of modern, sustainable wastewater recycling technologies and underscores the importance of utilizing local resources to mitigate groundwater pressure and ensure supply security during periods of drought.”

At the heart of Reuse Brew’s production lies Xylem’s advanced ozonation technology, paired with sophisticated filtration and purification processes, including nanofiltration. These technologies effectively remove chemical and microbial contaminants through oxidation, adsorption, and photolysis, ensuring the beer’s safety and quality.

“The source of water should not determine its value, but rather its safety and quality,” said Professor Jörg E. Drewes of TUM. “Our collaboration with Xylem on the Reuse Brew project underscores the practicality of converting wastewater into safe drinking water with existing technologies.”

The Weissenburg wastewater treatment plant, known for its excellence in wastewater treatment and trace substance removal, has been crucial in supplying water that meets stringent drinking water standards, thanks in part to Xylem’s innovative technologies.
