Abstract: FIELD: thermal disinfection; waste disposal.  
     SUBSTANCE: invention relates to the field of thermal disinfection and disposal of organic waste in solid, liquid and gaseous state, and can be used in various industries related to the processing of biomass waste. The method includes the separation of waste into solid, liquid and gaseous categories. A mixture of liquid and solid waste is subjected to two-stage centrifugal dehydration with the separation of a solid fraction and a liquid phase. In this case, the dewatered sludge of the solid fraction before thermal drying is subject to additional centrifugal dehydration in the filtering stage of the centrifuge with the release of solid sludge and filtrate. The dried sludge is decontaminated and disposed of in the combustion chamber, where suspension water-coal fuel, prepared on the basis of coal sludge and filtrate, is used as fuel, and ventilation emissions from industrial premises are used as blast air for the boiler unit of the boiler house. Regulation of the volume of supply of blast air at variable load is carried out by changing the volume of exhaust gases formed after thermal vortex drying of the solid phase sediment sent for mixing with ventilation emissions. The technical objective of the present invention is to reduce the emission of pathogenic microorganisms and viruses into the biosphere and energy consumption for the process of disinfection and utilization of thermal energy. 
     EFFECT: invention is aimed at reducing the release of pathogenic microorganisms and viruses into the biosphere, increasing the productivity of the system, reducing energy consumption for the process of disinfecting waste, disinfection of biologically hazardous organic waste, which is also in a gaseous state, by heat treatment in the combustion chamber of a heat-generating unit using the exhaust ventilation air of the premises as the blowing air of the heat-generating unit; utilization of the heat of the exhaust air used as a blast for the boiler units of the boiler house, which ensures a decrease in energy consumption for heating the supply air; reduction of energy consumption for air disinfection, with the exclusion of a separate operation for processing the removed air from the technological cycle, by combining the operations of fuel combustion and thermal disinfection of gaseous waste.
