Research On The Dilemma And Countermeasures Of The Implementation Of Municipal Solid Waste Classification Policy In Tianjin

With the rapid development of China’s social economy,the improvement of people’s material standard of living and the transformation of life style,the output of municipal solid waste(MSW)is increasing day by day,and the composition of MSW is becoming increasingly complex,which not only increases the risk of urban environmental pollution,also has the bad influence to the city economy development.How to deal with the environmental,social and economic problems caused by the rapid increase of domestic waste and realize the green and sustainable development of cities has become an important issue to test the government’s ability of governance.Through the analysis of domestic and foreign solid waste treatment process and the successful experience of advanced cities,many cities think that solid waste classification has become an effective means to solve the dilemma of urban solid waste treatment.Since the pilot work of MSW classification was started in Tianjin in 2012,some achievements have been made.However,with the deepening of the MSW classification,some obstacles have emerged gradually.The dissertation takes "Research on the implementation of municipal Waste classification Policy in Tianjin" as the research object.Firstly,it studies the domestic and international literatures on domestic waste classification and policy execution,and understands the context and status quo of relevant research at domestic and international.Then,based on the theoies of policy implementation,recycling economy and multi-governance,the framework of theoretical research is constructed.After sorting out the management situation of MSW and the current MSW classification policy in Tianjin,the execution situation and effect of MSW classification policy in Tianjin are deeply analyzed by using the "Horn-Meter" policy implementation system model and questionnaire survey method,and the existing problems are analyzed and the causes are discussed.The dissertation compares and summarizes the advanced experience of countries and cities in MSW classification policy and implementation.Finally,according to the causes of the dilemma of Tianjin MSW classification policy implementation and the domestic and international solid waste classification advanced experience,combined with the reality in Tianjin and the above-mentioned basic theoies,countermeasures and suggestions for optimizing the implementation of the waste classification policy in Tianjin are proposed.The dissertation also thinks about the unified management of domestic waste in urban and rural areas,hoping to promote MSW classification,in Tianjin as a whole.
