Description: The Tianbao and Shicun areas of Guyijing Community are typical urban villages, with 123 registered households and a registered population of 550. The permanent population is 1,297 and the migrant population is about 900. Since this area is located on one side of the ring road and is crossed by high-voltage lines, it is designated as landscape land in urban planning. The villagers have been looking forward to being demolished before, but there are no demolition plans in the near or long term. The local villagers are very dissatisfied. At present, most of the villagers' houses are rented out to migrant workers. At present, the entire area is under closed property management, with basic services provided by the street property management company. There is no classification of garbage. The daily domestic waste output is 1.6 tons, and the annual garbage volume is about 600 tons. There are two collection points for recyclables in the village, which are managed by outsiders and the government does not intervene in the management.
Since the land has two subway stations that can be reached on foot in 10 minutes, and by car in 5 minutes, you can reach the "rich area" in south Nanjing Hexi. It is the closest urban village to Nanjing city; there are ponds, vegetable fields, and The river has certain natural resource advantages, and some business activities can be carried out in the future, with the possibility of increasing the villagers' income.

Main problems:
1. Residents lack awareness of garbage classification. There is still a long way to go before the classification of domestic waste can be transformed from advocacy behavior to personal responsibility behavior.
2. Residents have long been accustomed to a unified garbage collection model. The accuracy of domestic waste classification is low, there is a lack of accurate quantitative statistics of various types of domestic waste, and food waste composting has not yet been carried out;
3. Residents lack awareness of the "zero waste" action. They do not have the idea of classifying garbage when throwing away garbage. They do not have a comprehensive and in-depth understanding of garbage classification knowledge, and they lack methods and measures to encourage participation in source reduction.

Solutions:
1. Establishment of ?zero waste community? management mechanism
2. Creating a ?zero waste community?
3. ?Zero Waste Community? publicity, education and training
4. Summary and sharing of ?zero waste community? action experience

Anticipated outcomes:
1. From the perspective of reduction: The first principle of reducing domestic waste management is to start from the source and stay away from the old path of not sorting. The Tianbaoshi Village Area Zero Waste Innovation Practice Project has clear ideas and scientific and effective methods. The project can become a benchmark for the classification and sorting of domestic waste in Yuhuatai District, Nanjing.
2. From the perspective of reuse: In the Tianbao Shicun Area Zero Waste Innovation Practice Project, the source reduction and classification rate exceeds 90%, the resource recovery rate is 85%, and the purity of various materials after classification exceeds 99%, containing 85% Kitchen waste is converted into humus on-site, with nitrogen, phosphorus, and potassium content meeting standards, and 20% of recyclable materials being fully utilized. This reduces 85% of waste entering incineration plants and landfills every day, and reduces 85% of outbound transportation. quantity, reducing transportation costs. For example, kitchen waste is converted into humus and used directly on the vegetable field to grow vegetables, which realizes the reuse of domestic waste and realizes on-site reuse of second-hand materials.
3. From the perspective of promotion significance: The Tianbaoshi Village Area Zero Waste Innovation Practice Project and high-quality primary waste treatment methods have promoted the establishment of application models, making the zero-waste construction of urban village communities visible, tangible, and learnable. It has broad market and promotion value.
