The results of theoretical calculation of biogas yield in psychrophilic, mesophilic and thermophilic conditions, as well as in the combined fermentation of the substrate. Based on these data, the advanced technology combined fermentation of agricultural biowaste. This will provide baseline data for the development of new structural and technological schemes of biogas plants that will improve the efficiency of processing animal waste due to the intensification of the process of bioconversion.

The rational technology biotreatment of agricultural waste, including next operations: pre-preparation of raw materials, acid stage fermentation of the substrate and alkaline stage was developed. Advantage is manifested in the fact that in each phase are optimal conditions for the development and life activity of the microbial population, which is necessary to improve the efficiency of fermentation of biomass. The biogas plant with a double – chamber bioreactor was developed, scale tests conducted and their results were shown. A method of calculating the basic parameters of the technological equipment for processing waste were developed.
