The farm of Andreas Mehli in Chur, with around 100 dairy cows, serves as a showcase for combining modern livestock farming with innovative energy generation. The farm places great emphasis on sustainable circular economy principles and the efficient use of available resources.

A FlexBio module for manure digestion was installed, complemented by gas purification, gas storage, and energy utilization of the produced biogas. This project marked an important step toward reducing emissions and achieving self-sufficiency through renewable energy, while also laying the foundation for a long-term partnership.

From this successful collaboration, GRegio Energie AG was founded by Andreas Mehli, who is now the official FlexBio representative in Switzerland and a key partner for sustainable agricultural energy projects.

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.”
