“变废为宝”有新招 重庆建成国家级绿色工厂170家、绿色园区16个

Core Viewpoint - The article highlights the efforts of Chongqing in establishing a "waste-free city" through effective waste management and resource recycling, showcasing initiatives like the transformation of kitchen waste into biodiesel and the recycling of industrial waste [1][2]. Group 1: Waste Management Initiatives - Chongqing's waste management includes the collection of kitchen waste, which is processed to extract waste oil for conversion into biodiesel, supporting downstream industrial companies [1]. - The "circular economy" concept is emphasized, where waste materials such as transformer oil are processed to prevent soil and groundwater pollution, with a focus on safe and efficient disposal [2]. - The Chongqing Electric Power Resource Recycling Center has dismantled over 7,000 transformers and 6,000 tons of cables, producing more than 25,000 tons of high-quality recycled resources [2]. Group 2: Community Engagement and Technology - The implementation of smart recycling devices in residential areas allows residents to recycle materials like paper and plastic efficiently, with automatic weight measurement and payment systems [3]. - Advanced waste sorting technologies, including AI and robotic arms, are used to ensure precise separation of kitchen waste from other types of garbage, enhancing the recycling process [3]. - Organic waste processed in the "venous industry park" generates methane, which is purified and converted into clean electricity, contributing to the local power grid [3]. Group 3: Cross-Provincial Collaboration - Chongqing and Sichuan have established a cooperative mechanism for the cross-province transfer of hazardous waste, improving the efficiency of hazardous waste disposal [3][5]. - The "white list" system allows companies to transfer hazardous waste to approved facilities, streamlining the disposal process and reducing associated costs [5].
