ANALYSIS OF ECOLOGICAL-ECONOMIC APPROACHES AND CIRCULAR ECONOMY MODEL IN HOUSEHOLD WASTE RECYCLING
Keywords:
Municipal waste, circular economy, anaerobic fermentation, biogas, wood-polymer composites, renewable energy.Abstract
The article is devoted to a comprehensive study of the environmental and economic efficiency of converting household waste into resources based on the principles of a circular economy. The study systematically analyzes the techno-economic indicators of anaerobic fermentation and biogas technologies of organic waste, decentralized processing of plastic waste based on additive technologies, and the production of wood-polymer composites. The results show that anaerobic processing of organic waste sharply reduces greenhouse gas emissions and creates a constant flow of energy in the form of electricity and heat. Local processing of plastic polymers reduces logistics costs from $19.64/kg to $0.61/kg. The article scientifically substantiates the institutional and technological mechanisms of the transition to a circular economy and the possibilities of their application in the conditions of Uzbekistan.
