STUDY ON THE INFLUENCE FACTORS OF URBAN WASTE RECYCLING FROM THE PERSPECTIVE OF URBAN ENVIRONMENTAL CONVERNANCE.

Urban waste treatment has become an important part of urban environmental governance, and the efficiency of waste classification and recycling affects the ecological environment construction of the whole city. At present, the urban waste classification and recycling system in China is not perfect, and the residents' awareness of waste recycling is insufficient, which restricts the urban green ecological development. To solve this problem, this paper first analyzes the concept of garbage classification and recycling, summarizes the classification and recycling process of three commonly used garbage classification methods, including terminal classification, front-end rough classification and front-end subdivision, and analyzes the advantages and disadvantages of each method. This paper puts forward the calculation formula and calculation process of waste recycling rate, which provides a theoretical basis for the investigation and analysis of waste classification. Through the analysis of the statistical data of the relevant environmental sanitation departments and the commercial departments, it is concluded that in the past 10 years, the amount of urban domestic waste recycling has increased year by year, from 35.463 million tons in 2010 to 56.984 million tons in 2019, with an average annual growth rate of about 6%; The treatment capacity of non recyclable waste has gradually decreased since 2014, and it will be reduced to 137.89 million tons in 2019; Since 2010, the garbage recovery and utilization rate has increased year by year, from 19.6% in 2010 to 29.3% in 2019. The garbage recovery and utilization rate has increased significantly. Through questionnaire survey, this paper analyzes the main factors affecting garbage collection, and concludes that only 22.5% of the residents have a very good knowledge of garbage classification, while 38.5% of the residents have a very poor knowledge of garbage classification.
