Analysis of the state of the solid municipal waste management system in St. Petersburg over the past 25 years

Abstract

The article examines the state of the waste management system in St. Petersburg over the past 25 years. It is shown that over 25 years, the environmental damage to the waste management system in St. Petersburg has increased 2.22 times, which indicates that the system has not been practically improved over the past years. Throughout the 25 years under consideration, the bulk of the solid municipal waste generated in St. Petersburg has been exported to the landfill, which is approximately 88 % of their total amount. The remaining 12 % is processed into compost at waste recycling plants. At the moment, in St. Petersburg there is a system for collecting hazardous waste from the population, which includes: hazardous waste collection points "Ecopoints", mobile hazardous waste collection points "Ecomobiles", metal terminals for receiving hazardous waste "Ecoterminals", as well as those designed to receive spent batteries, i.e. batteries "Ecoboxes" installed in specially selected places convenient for citizens. The work of the city's hazardous waste collection system from the population has been carried out since 2010, it is being improved, and is aimed at extracting hazardous waste generated by residents of St. Petersburg from the total volume of solid municipal waste generated by them. In conclusion, it is concluded that in the future in St. Petersburg it is necessary to develop directions for reducing the amount of waste exported to landfills by separating organic fraction from the main stream of municipal solid waste coming for processing, separating hazardous waste from them, as well as using high-quality sorting and deep processing of incoming solid streams municipal waste with the extraction of useful fractions from them, which can be used as secondary raw materials and for energy production
