Plastic waste takes first place in terms of cost and rate of accumulation among municipal solid waste. Recycling of plastic waste contributes to a significant reduction in the use of primary resources, reducing the harmful effects on the environment. The purpose of the study is to develop practical recommendations for optimizing recycling schemes for household plastic waste based on an assessment of their environmental and economic efficiency based on an analysis of the current situation in the waste management system in the Sverdlovsk region. The work analyzes the regional policy on waste management and the experience of processing municipal solid waste. A project is proposed to create a production for processing PET plastic with an assessment of its environmental and economic efficiency. For the first time, the additional environmental effect of replacing primary raw materials with secondary ones during project implementation was presented.
