Territorial pattern of municipal solid waste landfi lls in the republic of Tatarstan

The article discusses the problem of assessing the spatial organization of household waste storage. The authors analyze the territorial structure of municipal solid waste (MSW) facilities in the Republic of Tatarstan. Specific features of the functioning of existing MSW landfills are analyzed, and the dynamics of their filling is studied. Based on the method of interpreting satellite images, the rate of filling the plots of the solid municipal waste landfill in the city of Almetyevsk is demonstrated. Using the multidimensional cluster analysis, the development levels of the sphere of solid waste management in the municipal districts of the republic are compared. Based on the data on the number of landfills, the mass of removed waste, the provision of container sites, the mass of generated and unaccounted waste, the municipal districts of Tatarstan were grouped into 3 clusters with favorable, satisfactory and tense situation in the sphere of waste management. The functioning of the waste disposal system in the region was assessed. Territories with high concentration of waste in a limited space, located in the zone of influence of large cities of the republic and being the most promising from the point of view of the development of technologies for deep waste processing and biogas production, have been identified as optimally functioning. Using geographic information technologies, the authors assess the territory of the region from the point of view of possible solid waste landfills location. Based on the data on land use characteristics, soil composition and environmental requirements, a map was compiled showing the areas unacceptable and potentially suitable for the construction of MSW landfills. Settlements, agricultural lands, summer cottages, areas of industrial and military facilities, garages, forests, environmental areas, water bodies, and roads were all considered as limiting factors. Analysis of the map allowed a conclusion that there are territories suitable for locating of MSW landfills in the central and eastern parts of the republic, but there are practically no options in its western part, especially in the Kazan agglomeration zone.
