Abstract:
Despite various instruments to promote the fermentation of liquid manure in biogas plants, at present about 70 % of the liquid manure produced is still spread untreated on agricultural land. In about 7,600 of the approximately 8,350 agricultural biogas plants in Germany, liquid and solid manure are used for biogas production. Taking into account the provision of electricity, the use of liquid/solid manure is estimated at around 53 million tFM in 2017. Despite the implementation of a special remuneration category for manure-based biogas plants under the Renewable Energy Sources Act (EEG) 2012, a large part of the potential remains untapped. Major obstacles to the use of additional quantities of liquid manure for biogas production are regulations within the EEG and in the Fertilizer law. The limitation to 75 kWel installed power for manure-based biogas plants according to EEG prevents site-adapted concepts. Strict regulations regarding retention times in a gas-tight system lead to additional costs for plant operators, especially for manure-based biogas production. A lack of perspective after ending of EEG-compensation represent obstacle to the further use of liquid manure in biogas plants. Different measures for the preservation of the existing slurry fermentation and further expansion of the slurry fermentation are to be presented.
