A medium-sized brewery in Germany had been operating its own wastewater treatment plant for many years, but the system was associated with high electricity costs and significant effort for sludge disposal. To improve both the efficiency and sustainability of wastewater treatment, a new solution was implemented in cooperation with FlexBio.

A FlexBio anaerobic wastewater treatment module was installed, complemented by gas cleaning, gas storage, and energy recovery from the produced biogas in a combined heat and power (CHP) unit with an electrical output of 20 kWel. This setup not only treats wastewater more efficiently but also generates electricity and heat for in-house use.

As a result, the brewery benefits from significantly lower operating costs and a sustainable improvement of its CO₂ footprint — a successful combination of brewing tradition and modern environmental technology.

Feedback

Urs Imlig

Appenzeller Milchspezialitäten AG

“The wastewater volumes kept increasing. FlexBio was able to provide us with a mobile pilot plant. After successful testing, the plant was quickly installed thanks to its modular design. And everything has been working very well and smoothly together.”

Alfred Oberlindober

CEO & Owner of the Private Brewery Schönram

“We are direct dischargers and, due to growth and the resulting increase in wastewater volumes, we reached the capacity limits of our existing treatment plant. In our search for a solution, we found FlexBio Technologie GmbH to be a competent partner. The cooperation has proven to be highly profitable. We particularly value the modular and flexible design, which can be expanded at any time.”

Josef Blüml

Halsbacher Qualitätsfleisch GmbH

“The compact container solution with drum screen, anaerobic stage, and MBR provides complete wastewater treatment. We are particularly pleased that we can reuse the treated water – this saves operating costs and is a real advantage for our environmental and sustainability goals.”

Ludger Seggering

Popp Feinkost GmbH

“Wastewater is full of energy. We were looking for a solution and found it with FlexBio – generating biogas from wastewater. We are satisfied with the installation of the plant. We are satisfied with the service. And we are satisfied with the results.”

Andreas Mehli

GRegio Energie AG

“FlexBio makes slurry valuable again! With the new farm biogas plant, FlexBio transforms slurry and organic waste into clean energy and high-quality natural fertilizer. In this way, sustainability becomes a real opportunity for agriculture – and the vision of paying for the tractor with slurry comes within reach.”
