Abstract: Results of investigation of the possibilities of treatment of animal by products to biogas and estimation of the energy conversion parameters are presented in this paper. It was determined the content of methane in biogas and energetic potential of animal by-products. The laboratory scale tests with mixtures of animal by products and green biomass were executed and estimated that cumulative and volumetric biogas yield, from treated substrates and volatile solids, depend on volumetric load of biogas reactor. The biogas yields of 39-66 m3 from 1 tonne of treated substrates or 0,33-0,52 m3 from 1 kg of volatile solids, and 63-69% methane concentrations in biogas were determined. The highest energy efficiency coefficient was found at 2,0 kg/(m -d) organic loading that is in the range of 3,22 to 4,4!
