Biomass chopper

The Schumacher biomass chopper

The use of farm fertiliser instead of energy plants in biogas digesters causes an economic and ecological benefit. This biomass has to be broken up to use it in biogas plants. The process also enables higher and faster biogas production.

The new and mobile Rasspe RS CutMaster is a robust and easy-to-handle biomass processing system that is able to treat a wide range of different substrates.
