Besides other recyclable materials, biodegradable waste is collected here and composted. During the composting process heat is generated due to aerobic biological processes. As the exhaust air from the rotting heaps has to be cooled down due to process reasons, the heat has to be transferred to an auxiliary medium. Until 2005 the heat was set free to the environment by free air cooling. The thermally driven heat pump instead utilises this heat and supplies heat on a useful temperature level to a local district heating grid. The local district heating grid supplies heat to office buildings of VIVO GmbH as well as to a nearby industrial area. Hence, the heat pump has two beneficial effects on this application, it cools down a process were cooling is needed and uses this energy for fuel saving in a heating grid, which runs basically on oil burners instead
