Abstract. Introduction. Today, one of the most important global challenges is the efficient and economical use of traditional fuel and energy resources, the preservation of ecological balance, and the reduction of harmful emissions released into the environment. Materials and methods. The biogas production process in a combined bioenergy system is carried out through the integrated utilization of biomass resources with a moisture content of 90–92%. Livestock and poultry wastes are loaded into a 0.5 m³ bioreactor, where a thermophilic temperature regime is maintained using a solar collector. Results. During the research conducted in the bioreactor, it was observed that under thermophilic temperature conditions, the efficiency of biogas production increased by 10–15%. As a result of the thermal processing of 100 kg of wood chips in a 0.5 m³ pyrolysis reactor, it was determined that on average 25–30 kg of solid biochar, 45 kg of liquid biofuel, and 30 kg of pyrolysis gas are produced. Calculations also showed that 5–6 m³ of biogas generated in the bioreactor is sufficient to carry out the pyrolysis process. Conclusion. In a combined pyrolysis–biogas system, it is possible to reuse the heat generated during the pyrolysis process for heating the bioreactor through the integrated utilization of energy flows.
