A state-of-the-art biogas plant with an electrical power output of 370 kW was built on behalf of KWA Bioenergie Windischbuch GmbH und Co. KG at the Baden-Württemberg State Institute for Pig Breeding in Windischbuch. Renewable raw materials are used in addition to liquid pig manure (a residue of the test station), supplied by the farmers who participate in the company. A major share of the waste heat of the biogas plant is delivered to the research institute. The operator company guarantees the complete supply of heat to the test site through a heat supply contract. The gas burner of the heat supply features a dual-fuel burner specifically designed for biogas and serves as emergency flare stack.
