“无废城市”, 存量固废治理, 指标体系优化

Abstract:

The construction of "Zero-waste City" is a crucial step in advancing ecological civilization and building a Beautiful China. It is also a key measure for achieving synergistic effects of pollution and carbon reduction. China’s current work plans and indicator systems for "Zero-waste City" construction provide essential guidance and serve as the primary basis for evaluating "Zero-waste City" development effectiveness. They encompass the comprehensive management and treatment of both newly generated and existing solid waste. However, central government inspections on eco-environmental protection during the 14^th Five-Year period revealed several issues in the management of existing solid waste. These include illegal dumping, incomplete remediation of historical waste, overburdened landfills, and inadequate leachate management. These problems highlight shortcomings in policies, planning, and design related to existing solid waste management, underscoring the urgent need for improvement. This study discusses the significance of existing solid waste management in achieving the objectives of "Zero-waste City" construction based on the present state. It proposes the inclusion of "existing solid waste management" as a primary indicator in the current indicator system, subdivided into three secondary indicators: "existing municipal solid waste management", "existing construction waste management", and "existing industrial solid waste management", further detailed into six tertiary indicators. This study also explores the implications of these new indicators and demonstrates their feasibility through case studies. This improvement enhances the policy guidelines of “Zero-waste City” construction, motivates more cities to strengthen existing solid waste management, and supports the high-standard development and realization of "Zero-waste City".
