The traditional brewery Arcobräu Gräfliches Brauhaus GmbH in Moos faced the challenge of excessive wastewater volumes from beer production, which were overloading the municipal treatment plant. Under pressure from local authorities, the company had to act quickly to ensure sustainable production continuity.
In the first expansion stage, a FlexBio anaerobic wastewater treatment module was installed. Shortly thereafter, the second stage followed with two additional modules, complemented by gas cleaning, gas storage, and the energetic utilization of the produced biogas in two combined heat and power (CHP) units with an electrical output of 50 kWel each. This setup significantly reduced the brewery’s wastewater load while generating renewable energy in the form of heat and electricity for on-site use.
Thanks to its modular design, the system can be easily expanded, providing a solid foundation for long-term, sustainable, and economically efficient beer production.
