Study on urban domestic waste recycling process and trash can automatic subdivision standard

Objective In order to propose a garbage classification standard suitable for automatic subdivision of intelligent classified trash cans, and to improve the garbage recycling process. Methods Based on the status of urban domestic waste recycling process, process analysis and comparison method was used to analyze the related problems. According to the composition and nature of urban domestic garbage, the automatic subdivision standard suitable for intelligent classified trash cans was proposed. Result It is concluded that the traditional process has the problems of centralized treatment and vague positioning of each subject. Therefore, the keys should focus on the front-end classification to removal centralization, distinguish the positioning of each subject clearly and use technology to drive the classification. From these, the paper analyzes the composition and nature of recyclable garbage and harmful garbage to propose the automatic subdivision standard. Conclusion Only by making full use of people’s subjective initiative, using intelligent classified trash cans as carriers to subdivide automatically, can improve the garbage recycling process. This has important practical value and significance for solving the problem of urban diseases in China.
