Abstract

The article examines the sources of solid waste generation, their impact on the environment and human health. The morphological composition of municipal solid waste (MSW) and the factors influencing the dynamics of their change were analyzed. Based on the results of the study, the physical and thermal parameters of solid waste- ρ, φ were determined and the elemental composition and heat of combustion of solid waste were analyzed. It was found that the physical properties of MSW and the morphological composition of MSW depend on the seasons and other conditions. An energy balance diagram for heliothermal processing of solid household waste with different morphological compositions in a solar device for thermal treatment of solid waste was calculated and it was found that the share of solar energy for thermal processing of solid household waste was 78%. As a result of the thermal processing of organic compounds, which formed the morphological composition of the MSW, it was found that it is possible to obtain alternative fuels and produce thermal energy and electricity in the traditional way.
