Rationalization of municipal solid waste management in the city (using the example of the activities of EcoSputnik LLC in the city of Orenburg)

It is shown that one of the problems of Orenburg at present remains the alienation of land for the solid municipal waste landfill, the impact of the landfill on the atmospheric air and groundwater. It was established that in order to ensure environmental safety in the city of Orenburg, separate waste collection into containers is organized. Solid municipal waste is received at the landfill from private and multi-storey residential buildings of the city, from municipalities that are part of the city, from enterprises and organizations. Waste from garbage containers is taken to the solid municipal waste landfill, the landfill sorts incoming waste, and waste is not recycled. It was established that in the morphological composition of the incoming waste from the containers, more than 80% of the waste is used polymeric materials, glass and paper, which are collected separately in the city in containers, food and degradable organic materials. The share of organic materials degradable in the environment in solid municipal waste is 40,5%, their separate collection in the city is not carried out. It has been calculated that 18 biogas plants KOBOS-1, one glass processing plant TOSS, 4 plastic processing plants STANKO-2000, 5 waste paper processing plants BDM-3 will be required to process the waste generated annually. Calculations show that processing MSW after sorting will allow obtaining 33974 tons/year of biogas, 14541 tons/year of sheet glass, 22425,6 tons/year of plastic products, 15330 tons/year of paper products and will reduce the area of land alienated for landfills.
