Geo-ecological aspects of sustainable development of multifunctional complexes for solid municipal waste management

This study is devoted to solving the problems of creating (new construction) municipal solid waste management (MSW) facilities on the territory of small settlements (municipal districts and regions) of the Volga Federal District. The most significant geo-ecological indicators providing a comprehensive assessment of the design and construction of a MSW landfill were identified and justified. Service life, capacity, landfill capacity for non-compacted waste, and landfill capacity for compacted waste are the main indicators. The technical indicators of the design objects are a set of main and auxiliary facilities serving the operation of the waste disposal site in accordance with its functional zoning. A comparative assessment of the geo-ecological, technical, economic and operational indicators of the construction of a MSW disposal facility was carried out by developing three options for organizing a waste disposal site (quarry, bulk, combined) for a reference landfill of solid municipal waste with a disposal capacity of up to 30 thousand tons per year with a storage area of 3 hectares. The degree of economic activity effect on the geological environment is considered from the maximum possible deepening to the refusal of deepening of MSW landfill site. The quantitative parameters obtained as a result of the study represent criteria for redundancy of design solutions as a percentage of the total cost of construction of waste management facilities. The calculations made it possible to develop an integrated system for assessing technical and economic indicators and resource and technological security of design solutions for measures implemented in the sphere of consumer waste management.
