Centralized co-digestion and efficient nutrient recycling

Abstract

The centralized biogas plants co-digest animal manure and organic waste, producing biogas and liquid fertilizer as a result. 19 centralized biogas plants are in operation in Denmark. In 1996 they digested 200,000 tonnes organic industrial wastes with 800,000 tonnes manure. The average gate fee for waste reception is around DKK 50 per tonne. Thus, the centralized biogas plants provide the organic waste producers with an economically attractive as well as environmentally sound recycling option. The farmers play a key role. It is a precondition that the farmers benefit sufficiently from the operation of the centralized biogas plant. An average economic advantage for the farmers of approximately DKK 5 in all per m{sup 3} slurry has been calculated. Even though this is a relatively modest amount, it is enough to generate interest on the part of the farmers. A further tightening of the legislation is expected in a few years concerning utilization of nutrients in manure and land applied organic wastes. This, together with increasing focus on odour reduction, is expected to add to the farmers interests in centralized biogas plants. At present biogas contributes with 2 PJ per year to the energy supply in Denmark. According to the official energy  More>>

At present biogas contributes with 2 PJ per year to the energy supply in Denmark. According to the official energy action plan, the total biogas production from all kinds of biogas plants is to be doubled by the year 2000 and increased 10-fold by the year 2020. A major part of this increase is expected to come from new centralized biogas plants. The annual potential for biogas production from biomass resources available in Denmark is estimated to be approximately 30 PJ. Animal manure comprises about 80% of this potential. (au)}
