Abstract:

The raw material base for biogas production shall be enlarged considerably by biomass processing that is efficient economically and in terms of energy consumption. At present, maize, whole plant corn silage and dung are of use primarily for the production of biogas. Since neither monocultures nor food competition are desirable, the research and development is focused on the expansion of raw materials such as beta beets, including beet leaf and lignocellulosic biomass, e.g. straw, dung, grassland cut and landscape management material.The raw materials are crushed and frayed out with special technologies to accelartehydrolysis in the biogas process. By this process further renewable raw materials can be used for fermentation, shortening the time for fermentation and increasing biogas yield. Moreover, the technology reduces cost because straw, dung and landscape management material, for example, are more reasonably priced than cultivated biomass. Furthermore positive influences on crop rotation, the reproduction of soil fertility and the conservation of nature can be expected.
