Summary
Biomasses from ecologically valuable areas (e.g. extensive grasslands) can not eco-nomically be used in conventional biogas plants as such substrates have a low di-gestibility. In the procedure proposed ensiled biomass from such vegetations are mechanically dried. Only the sap pressed out is used in the digester for methane production with retention times below 10 days and with methane yields of more than 450 l/kg organic dry matter. The heat produced in the combined heat and power plant is used on-site for drying the press cake. The dried cake is then processed to form a marketable solid fuel. The technology proposed has less demand towards the digesti-bility of biomass than conventional biogas techniques.
