Abstract: After the “four classifications” of MSW in Shanghai， the resource utilization of recyclable materials of glass， metal， plastic， paper and textile waste was a nationwide shortcoming in China’s domestic waste classification work. The quality and flow characteristics， recycling system status， recycling ways， related management policies and mechanisms of the recyclable materials in Shanghai domestic waste were analyzed through on-site investigation， videoconferencing， questionnaire survey， consultation and interviews. The main existed problems were discussed and suggestions for improvement were proposed. The results showed that the source classification of domestic waste in Shanghai had achieved remarkable results. The average daily collection amount of recyclable wastes was 7 000 t/d， mainly consisting of paper， metal and plastic waste. By the end of 2020， 1.5×104 recyclable recycling service points， two hundred and one transfer stations， ten distribution centers and sixty-four main recycling enterprises had been established. However， the scale of resource utilization of recyclables and efficiency were still low. Against the higher requirements of domestic waste management， the utilization of domestic recyclables needs to be improved in areas of laws and regulations， technical standards， classification methods， market cultivation， regional coordination， data statistics， inter-provincial supervision. On this basis， suggestions were given for designing a collaborative management mechanism.
