Einbecker Brauhaus AG, renowned for its centuries-old brewing tradition and as the originator of Bock beer, was faced with the challenge that the municipal wastewater treatment plant had become heavily overloaded due to the high wastewater volumes from production. Under pressure from authorities, immediate action was required to ensure sustainable production operations.
In the first expansion stage, two modules for anaerobic wastewater treatment were installed, complemented by gas purification, gas storage, and biogas utilization in a combined heat and power (CHP) unit. This significantly reduced the organic load of the wastewater while simultaneously generating electricity and heat for the brewery’s own use.
The plant is modular in design and future-ready: an expansion with three additional modules is planned to further increase capacity and to strengthen the Einbecker Brauhaus’s long-term sustainability strategy.
