Solid municipal waste technological equipment

In various regions of Russia, there is some sort of crisis in the handling of municipal solid waste. The National Project “Ecology” is aimed at solving this problem, as well as the federal projects “Integrated system of solid municipal waste management” and “Implementation of the best available technologies”. However, in the processing and disposal of waste, the problems of preserving the environment (ecology) often come into conflict with the financial component of the development of the industry (economy). The aim of the study is to determine the integrated environmental and economic efficiency of waste management at the regional level. The study considers the scheme of the technological process for the processing of municipal solid waste and assesses the efficiency of replacing the technological equipment at the “EcoResourcePovolzhie” enterprise based in the city of Togliatti. The authors suggest modernization of separation technology to improve the efficiency of waste processing. With the replacement of the existing separators with drum separators, screens RMZ TR-4500, the efficiency coefficients of the sorting and extraction process, the percentage of selection of secondary raw materials, increase. The costs of replacing drum separators were determined, the economic effect and payback period of the proposed modernization were calculated, as well as the environmental effect of reducing the flow of waste to the landfill, extending the life of the landfill, reducing the risk of the release of hazardous components into the air in the event of fire at the landfill, soil pollution and aquatic environment, as well as reducing disposal costs.
