    Based on numerous investigations on increasing the biogas yield of manure, a new concept was developed to increase the economical operation of manure based biogas plants by combining up concentration of manure with a more specific treatment of the recalcitrant lignocellulosic fiber fraction by implementing the treatment on the digested solid fraction. Catch crops have been identified as a sustainable co-substrate for biogas production with a high biogas potential. For exploiting this biomass for profitable biogas production, the biomass yield per hectare, harvest costs, TS concentration and specific methane yields are important parameters to be taken into account.
