Abstract:

The resident is one of the key subjects in the municipal solid waste separation and recovery system. Residents’ participation in source separation of domestic solid waste is one of the most important factors affecting the success or failure of the urban solid waste seperation work. In this study, in order to analyze the mechanisms of residents’ waste seperation and recovery behaviors, Suzhou City was chosen as a case, a field questionnaire survey of the residents in its central area was conducted, and the key factors affecting residents’ waste sorting and recovery behaviors and their paths were explored using the statistical analysis method of structural equation modeling (SEM). The research results show that the domestic solid waste source separation behaviors of the surveyed residents are closely related to four subjective factors and seven objective factors, and the latter’s comprehensive effect is almost twice that of the former. Among all the factors, the latent variable “environmental facilities and services” has the greatest combined impact, while “public education”, “convenience of recycling facilities”, “convenience of separation facilities”, “willingness to participate”, and “environmental awareness” are the top five factors that affect residents’ domestic solid waste separation behaviors. In order to further accelerate the source separation of domestic solid waste in China, it is recommended to strengthen the planning and construction of municipal solid waste separation and recycling facilities, extensively carry out publicity and education on domestic solid waste separation and recycling, improve relevant laws and regulations, and establish an effective incentive and restraint mechanism.
