Study on Compulsory Classification Management and Behavior Synergy of Municipal Solid Waste

There is a general phenomenon of incoordination between garbage classification management and participation behavior, which seriously affects the sustainable management efficiency of domestic garbage. In order to solve this problem, this paper introduced the subject-object-process model into the waste classification management system, and constructed a mandatory classification management model of municipal solid waste and a comprehensive evaluation index system. Taking Beijing, China, as an example, the coupling coordination degree of garbage classification behaviors of residents in different was compared, and the coordination status of household waste management and behaviors was obtained. The results show that the synergy between government management and residents’ household waste classification behavior is between 0.40 and 0.68, and the synergy between enterprises’ participation in governance and residents’ behavior is between 0.45 and 0.75. The coordination degree between domestic waste management and residents’ participation behavior is generally in primary coordination or slight imbalance. The synergy degree between the secondary indicators of domestic waste management and residents’ behavior is higher than that of the tertiary indicators. Superposition effect of integrated management measures is better; among the psychological factors affecting residents’ classification behavior, the awareness rate and recognition degree of waste classification are very high, the awareness of environmental responsibility and social pressure are lagging behind. The study of synergy under the framework of subject-object-process not only quantifies the overall synergy between management and residents’ behavior, but also provides a method to further implement garbage classification management in a targeted manner. Based on the synergy analysis, according to the weak links of various regions, classified management is carried out around publicity and education, supervision and management, assessment, rewards and punishments.
