The plant in Montauban (de Bretagne) converts the produced biogas into electricity. The available heat is utilized in a greenhouse complex. To make this happen, solid and liquid manure are digested, including categorized waste (such as waste from restaurants). For the categorized waste HoSt supplies hygienisation meeting EU standards and regulations at all time. In this project a significant amount of straw can be digested due to the application of a straw input line.
