Abstract

Sustainable waste management (SWM) practices are crucial for tackling environmental concerns under a circular economy (CE) scope. Thirty-one OECD countries have been evaluated on their national SWM performance via Malmquist data envelopment analysis (DEA) methodology from 2000 to 2021. The Malmquist (MPI) and Malmquist-Luenberger (MLPI) productivity indices are compared based on their total factor productivity (TFP) and its elements (i.e., efficiency and technological changes). Both models have the gross domestic product (GDP) as a desirable output, but MLPI also incorporates municipal solid waste (MSW) generation and greenhouse gases (GHGs, i.e. CO₂ and CH₄) as undesirable outputs. MLPI has a lower average performance (1.74%) than MPI (4.42%), meaning that the incorporation of waste and GHGs has diminished an OECD country’s SWM performance by 2.5 times on average. In essence, it is innovation that drives TFP in the selected countries. Overall, the synergistic implementation of SWM practices, Malmquist DEA-based methodology, and CE principles is crucial for advancing sustainable development and achieving a circular and resilient future. The manuscript also offers policy implications regarding the need of financial incentives, vocational training, and fostering stakeholder encouragement in the waste sectors to implement CE solutions.

监测经合组织国家的可持续废物管理：Malmquist 生产率方法。

可持续废物管理（SWM）实践对于解决循环经济（CE）范围内的环境问题至关重要。从 2000 年到 2021 年，经合组织通过 Malmquist 数据包络分析 (DEA) 方法对 31 个国家的废物管理绩效进行了评估。马尔姆奎斯特（MPI）和马尔姆奎斯特-伦伯格（MLPI）生产率指数是根据其全要素生产率（TFP）及其要素（即效率和技术变化）进行比较的。两个模型都将国内生产总值（GDP）作为理想产出，但 MLPI 还将城市固体废物（MSW）的产生和温室气体（GHGs，即 CO2 和 CH4）作为不理想产出。MLPI 的平均绩效（1.74%）低于 MPI（4.42%），这意味着纳入废物和温室气体后，经合组织国家的社会安全管理绩效平均降低了 2.5 倍。从本质上讲，是创新推动了选定国家的全要素生产率。总之，协同实施 SWM 方法、基于 Malmquist DEA 的方法和 CE 原则，对于推进可持续发展和实现循环、有韧性的未来至关重要。该手稿还提供了有关需要财政激励、职业培训和促进废物处理部门利益相关者鼓励实施能源效率解决方案的政策影响。

期刊介绍： Waste Management is devoted to the presentation and discussion of information on solid wastes,it covers the entire lifecycle of solid. wastes. Scope: Addresses solid wastes in both industrialized and economically developing countries Covers various types of solid wastes, including: Municipal (e.g., residential, institutional, commercial, light industrial) Agricultural Special (e.g., C and D, healthcare, household hazardous wastes, sewage sludge)
