A method for environmentally safe solid waste and biomass processing to increase the efficiency of electric power generation and other useful products, during which solid waste and biomass are loaded, crushed and shredded, and ferrous and non-ferrous metals are separated from them and supplied as marketable products to external consumers, and cleaned from metals shredded solid waste and biomass are accumulated, then accumulated shredded solid waste and biomass separated from metals are fed in the dosing method into the fast plasma gasification reactor, in the fast plasma gasification reactor the shredded solid waste and biomass are subjected to fast plasma gasification, during which melting occurs and a basalt-like slag is formed, which is processed to obtain granulated slag, and the obtained granulated slag, as a marketable product, is supplied to external consumers;
- part of the accumulated methane in the first constant volume gasholder is used for electric power and heat generation, while part of the generated electric power is supplied for own use, and the other part of the generated electric power and heat is supplied to external consumers, carbon dioxide captured from the exhaust gases formed during the electric power and heat generation is compressed, accumulated;
- in the absence of the need to generate electric power and heat, electric power for own use is generated from part of the accumulated methane in the first constant volume gasholder, wherein solid waste and biomass are subjected to vacuum and temperature drying, in the process of vacuum and temperature drying, vacuum extraction of volatile compounds and water steam from solid waste and biomass is provided, the steam-air mixture and volatile compounds are compressed and accumulated, then the accumulated steam-air mixture and volatile compounds are subjected to plasma cleaning-disinfection and superheated steam is generated, which, as a plasma-forming gas, is fed to the indirect arc plasma torches to the fast plasma gasification reactor for fast plasma gasification, and the steam-air mixture obtained in the process of plasma cleaning-disinfection is condensed, separating water steam from the steam-air mixture extracted from solid waste and biomass, and purified and decontaminated air is released into the atmosphere.
