Abstract: Municipal solid waste (MSW) classification is a national strategic objective and an important component of successful municipal solid waste management (MSWM). Some failures of pilot programs suggest that safeguarding measures are essential for MSW classification. A questionnaire survey of public awareness and attitudes toward MSW source-separated collection in Chongqing’s main districts was conducted, and the results indicated that the proportions of respondents willing to participate in MSW classification and provide money for it were 67.9% and 86.2%, respectively. The positive impacts of the overall-process management measures on promoting MSW classification in Chongqing’s main districts, including source-separated collection system, transportation system, treatment and disposal system, and environmental sanitation prevention system, were analyzed comprehensively. The analyses revealed that a 98% resident participation rate was obtained for MSW source-separated collection with the application of a cloud-based platform and traceability system. Moreover, the secondary transportation and comprehensive “4 + 1” (four waste incineration plants and one waste landfill) disposal mode showed significant advantages with respect to costs and environmental friendliness. In view of the environmental sanitation risks, the prevention and control of environmental sanitation were developed in Chongqing. The future prospects have also been discussed. The refinement and regionalization of source-separated collection are proposed as the possible solution.
