Kuhrerhof Farm in Chur is a modern agricultural enterprise that combines tradition with cutting-edge technology. The farm stands out for its strong commitment to sustainability and resource efficiency—an approach that has made it a model operation within the region.
In cooperation with GRegio Energie AG, a true flagship project is being realized: FlexBio is constructing a complete manure treatment system that is unique in its kind. The installation includes three manure digestion modules, complemented by gas cleaning, gas storage, and the utilization of the produced biogas in a combined heat and power (CHP) unit.
With this project, Kuhrerhof sets new standards in agricultural circular economy—reducing emissions, generating valuable renewable energy, and serving as an inspiring example far beyond the region.
