Abstract: On April 24, 2022, the Ministry of Ecology and Environment of China announced the construction list of "waste-free city" during the 14th Five-Year Plan period. As the key field of social governance, the accurate classification and treatment of community household waste sources is a key link affecting the construction and development of "waste-free city". Therefore, it is necessary to promote the integration of community sanitation and establish a smart, scientific, fine, and clean infrastructure system for intelligent classification of community household garbage. Relevant studies show that with the gradual implementation of garbage classification policies, regulations and documents, the proportion of all kinds of household garbage is also gradually changing. Among them, the proportion of recyclables, kitchen waste and harmful waste is gradually increasing, while the proportion of other garbage is gradually decreasing. Meanwhile, the improvement of the purity of kitchen waste also lays a foundation for its resource utilization beyond incineration and power generation. It analyzes the characteristics of typical residential communities and the prominent problems existing in the classification, transport, and treatment of domestic garbage inside them, focusing on the standardized, modular, and integrated intelligent garbage classification equipment and AI classification management, scheduling and maintenance platform, and puts forward the configuration principles of intelligent garbage classification infrastructure system in typical communities in Majuqiao Town of Tongzhou District, Beijing. This study can provide a reference and basis for promoting the planning and construction of intelligent garbage sorting and clean collection systems in urban communities in Beijing, Tianjin, Hebei and other areas in China.
