For this project in Chernozemen, Bulgaria, HoSt built a biogas plant with a capacity of 1.5 MWe, mainly based on the input of liquid cow manure with co-products as silage corn and straw.

The 1,5 MWe biogas plant is built with a solid feeding system, a liquid input system consisting of a pump and cutter, 2 digester tanks in combination with an after-digester tank, a separator system, after-storage tanks and a building with a control and heating room, a 1.5 MWe CHP and a room for the operator.

Host has developed a digesting concept to create the possibility to digest large amounts of straw. A high efficiency is realized by applying 2-step digestion with an after-digester tank together with a high quality type of mixing.
