Core Viewpoint - The transformation of waste into resources, exemplified by the recycling of cooking oil into biodiesel, reflects Chongqing's efforts in building a "waste-free city" that emphasizes efficient waste disposal and resource recycling [2][3]. Group 1: Waste Management and Recycling Initiatives - Chongqing's "waste-free city" initiative focuses on safe and efficient waste disposal, resource recycling, and reducing waste generation, having been a pilot city since 2019 [2]. - The "venous industry" concept is introduced, likening waste recycling to the body's venous system, aiming to address waste surplus and resource scarcity [3]. - The Chongqing Electric Power Resource Recycling Center has successfully processed over 7,000 transformers and 6,000 tons of cables, producing over 25,000 tons of high-quality recycled resources [4]. Group 2: Community Engagement and Smart Recycling - The implementation of "waste-free cells" such as "waste-free communities" and "waste-free parks" enhances public participation in waste sorting and recycling [5]. - Smart recycling devices in communities facilitate easy waste sorting, transforming the public's attitude towards waste management from obligation to willingness [5][6]. - Chongqing has established a comprehensive waste management system that integrates waste disposal and recycling, ensuring daily waste processing capacity of 36,400 tons across 78 facilities [6]. Group 3: Cross-Regional Cooperation in Hazardous Waste Management - A cross-regional cooperation mechanism between Sichuan and Chongqing has been established for the efficient disposal of hazardous waste, significantly reducing approval times for waste transfer [7][8]. - The partnership between companies in Sichuan and Chongqing allows for the resource recovery of hazardous waste, such as aluminum ash, expanding business opportunities for recycling firms [8].
