The article shows the results of research on the possibility and efficiency of disposal of human waste (municipal wastewater) and animals. Currently, there is a problem of energy supply to rural settlements in Kazakhstan. And if the supply of electric energy is stable enough, then there are big problems with heat supply: rural residents in most regions are forced to use coal for heating, which negatively affects not only the environment, but also the social situation, since fuel is getting more expensive every year, which is not to say about the income of the population. The purpose of the research is to develop technologies for obtaining thermal and electrical energy in the joint disposal of waste of the population and domestic animals. At the same time, such bioenergy installations should be inexpensive, energy efficient and environmentally friendly. Studies of the influence of various factors on the fermentation process have been carried out. The option of joint disposal of these wastes is being considered. A technological scheme of a biogas plant with complete utilization of biogas, with the production of methane and carbon dioxide, biohumus as products, has been developed. The scheme is waste-free. At the same time, municipal wastewater is separated and the biogas plant uses activated sludge together with the manure of domestic animals to produce biogas. An efficient bioreactor has been developed, horizontal with three compartments operating in automatic mode. The cycle of effective biogas production is 18 days. For every 10 m3 of joint disposal of municipal wastewater and cattle waste, an estimated biogas output of 196 m3, an estimated thermal power of 17 kW, and an estimated electrical power of 15 kW is expected. For example, the daily volume of municipal wastewater at the treatment facilities of Astana city averages about 180,000 m3/day. Accordingly, the estimated maximum capacity of a biogas plant for biogas output is 3,528,000 m3/day or 147,000 m3/hour, for thermal power of 306 MW/day or 12.75 MW per hour, for electrical power of 270 MW/day or 11.25 MW per hour. The considered variant of waste-free waste disposal technology allows creating energy-efficient, inexpensive small biogas and bioenergy installations that allow combining either 8-10 rural courtyards or several buildings of an urban settlement into a single waste disposal unit.
