本研究通过建立有效的层次模型丰富了可持续固体废物管理知识，并批评了废物再利用和回收属性之间的因果关系。强调了可持续废物再利用和回收的挑战和机遇，并为实践提供了方向。许多发展中国家和新兴国家一直在努力解决固体废物管理问题以及对材料再利用和回收活动的严格限制。然而，由于经济和政治制度水平薄弱，它的发展并不充分，再利用和回收工作尚未得到很好的落实。本研究旨在提出可持续的固体废物管理模式，并解决发展中国家废物再利用和回收的机遇和挑战。采用混合方法，使用系统数据驱动分析，包括内容分析、系统不确定性和复杂性、模糊德尔菲法、解释结构建模以及模糊决策试验和评估实验室。结果显示，19个有效指标集中在五个方面，其中循环资源管理、社会要求和城市可持续性是改善固体废物可持续管理的原因因素，涉及废物再利用和回收。有助于加强实践的最重要指标是循环经济、非正规部门、物质流分析、政策限制、废物处理技术。介绍了最先进的文献，并确定了进一步的机遇和挑战。
This study enriches sustainable solid waste management knowledge by establishing a valid hierarchical model and critiques the causal interrelationship between waste reuse and recycling attributes. The challenges and opportunities for sustainable waste reuse and recycling are emphasized, and direction is provided for practices. Many developing and emerging countries have been attempting to address solid waste management problems and serious restrictions on material reuse and recycling activities. However, it is not well developed, and reuse and recycling efforts have not yet been well implemented due to weak economic and political institution levels. This study aims to propose a sustainable solid waste management model and address opportunities and challenges for waste reuse and recycling in a developing country. A hybrid approach is adopted using a systematic data-driven analysis comprising content analyses, system uncertainty and complexity, the fuzzy Delphi method, interpretive structural modeling, and the fuzzy decision-making trial and evaluation laboratory. The results show that 19 valid indicators are congregated into five aspects, in which circular resource management, societal requirements, and municipal sustainability are causative aspects with the capability to improve sustainable solid waste management as it regards waste reuse and recycling. The top prominent indicators helping to enhance practices are the circular economy, the informal sector, material flow analysis, policy restrictions, waste treatment technologies. The state-of-the-art literature is presented, and further opportunities and challenges are determined.
