Abstract. At the moment, the amount of litter (with low humidity) pig manure in Krasnoyarsk Krai is approximately 900,000 tons. This allows to get at least 15,000–20,000 m3 of biogas. The purpose of this work was to adapt the technology and create an experimental plant for processing livestock wastes to produce biogas under climatic conditions of Krasnoyarsk Krai. The thermophilic fermentation regime was the most effective. In this case, the time of the reaction mixture being in the reactor with full biogas release reduced on average by 5–8 days. On the basis of bacteria inhabiting the cave formations of Krasnoyarsk Krai, an updated composition of introduced biological strains, used in the case of the thermophilic regime, was obtained. The application areas of the biogas plants (BGP) with different productivity, applied to the needs of consumers with the justification of economic efficiency, are marked. The estimated cost of BGP depends on the productivity and automation degree of the installation and can be on average from 60 to 500 thousand rubles. The sales promotion on the market of technical documentation and finished biogas plants, taking into account the growth of payable consumer demand, will lead to increase in the share of such installations to 70 %.
Keywords: technology of waste recycling, biogas plant, ecology, bioenergetics, thermophilic fermentation, biological strains, commercial and absolute economic efficiency.
