A long-established wine producer in Germany faced the challenge of excessive wastewater volumes from production, which were overloading the municipal treatment plant. Under regulatory pressure, the company needed to take immediate action. In cooperation with FlexBio, successful trials were first conducted using a mobile pilot plant before a full-scale solution was implemented.

The installation features an anaerobic wastewater treatment module, complemented by gas cleaning, gas storage, and energy recovery from biogas in a combined heat and power (CHP) unit. This setup significantly reduces the organic load in the wastewater while generating renewable energy for the company’s own operations.

The installed system represents the first expansion stage, with additional modules already planned to further increase capacity, strengthen long-term supply security, and advance the company’s sustainability strategy.

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.”
