Establish a "package" of supporting policies to create a "zero-waste city cell"
Lanzhou is an important central city, industrial base and comprehensive transportation hub in Northwest China, as well as an important node city in the Silk Road Economic Belt. Lanzhou is not only a national civilized city, in recent years, it has been listed as a national circular economy pilot city, the third batch of low-carbon pilot cities, selected as the first batch of national climate investment and financing pilot cities, the country's first pilot city to carry out domestic waste classification, China's municipal solid waste field national appropriate mitigation action project pilot city (NAMA project), national urban physical examination sample city, national "anti-pollution" pilot city, etc., has carried out the whole area of garbage-free governance, hazardous waste assessment and assessment, domestic waste classification, plastic pollution control and other actions. In 2020, the comprehensive utilization rate of general industrial solid waste was 97.7%, the harmless treatment rate of domestic waste was 95%, the recycling rate of waste agricultural film was 81.76%, the comprehensive utilization rate of crop straw was more than 85%, and the resource utilization rate of livestock and poultry manure was more than 76%.
In recent years, Lanzhou has built a domestic waste incineration project, hazardous waste disposal center project, medical waste centralized disposal project, general industrial solid waste comprehensive utilization and cement kiln co-disposal project, the city currently has 19 hazardous waste management enterprises, waste electrical and electronic dismantling treatment units 2, the city's solid waste reduction, recycling, harmless level continues to improve.
In order to solidly promote the construction of "zero-waste city", Lanzhou has formulated the "1+8+3" implementation plan for the construction of "zero-waste city" in the whole region, established the "three lists" of solid waste, responsibilities and tasks, established 47 construction indicators and "package" supporting policies, and successively introduced 17 supporting systems to further consolidate the "zero-waste city" institutional system. In addition, the "Lanzhou City Green Building Labeling Management Measures" and "Pesticide Packaging Waste Recycling and Treatment Management Measures" were issued, and the "Lanzhou Vegetable Waste Treatment and Utilization and Pollution Prevention and Control Management Measures" were revised, and the "Lanzhou Hazardous Waste Environmental Pollution Prevention and Control Measures" has been issued and officially implemented on January 1, 2024. Standardize disposal.
In order to create a "zero-waste city" co-construction and sharing atmosphere and form a good atmosphere for the participation of the whole society, the "Implementation Plan for the Creation of "Zero-Waste City Cells" in Lanzhou City was issued, tailor-made party and government organs, schools, production enterprises, scenic spots, shopping malls, communities (communities), hotels, hospitals, and parks, a total of nine cell types, to create a number of "zero-waste city cells", and plan to create at least 560 "zero-waste city cells" in the city during the "14th Five-Year Plan" period.
It is understood that in 2023, a total of 150 waste-free cells have been created in Lanzhou, and the construction results of the "zero-waste scenic spot" in Lanzhou Ink Danxia Scenic Area have been adopted and released on the WeChat public account of "China's Waste-free City Construction", and the response has been enthusiastic. "Waste-free city".
