A circular supply chain transition represents a significant sustainability step, which leads to resource optimization and longer product lifecycles. The electrical and electronic equipment (EEE) sector focuses on end-product lifecycle management as electronic waste (e-waste) alongside recycling and recovery operations for supply chain inclusion of components. This transformation faces considerable difficulty, primarily in developing economies, due to structural, regulatory, and technological barriers. The study identifies key impediments in e-waste supply chain systems by analyzing social, economic, and environmental sustainability factors, government regulations, technological advancements, and operational challenges. Using multi-iteration fuzzy Delphi, the factors were refined to 14 critical impediments, which were then prioritized and evaluated through fuzzy WINGS (Weighted Influence Nonlinear Gauge System). The findings highlight key cause impediments, including the dominance of the informal sector in e-waste handling (IIS), Ineffective policies and regulations (IPR), and Insufficient supply of e-waste to formal recycling centers (ISS), which significantly disrupt the efficiency of formal recycling processes. A comparative analysis with fuzzy DEMATEL revealed discrepancies in the influence of certain impediments, while sensitivity analysis confirmed the robustness and stability of the model. This research provides valuable insights for policymakers, government bodies, and industry stakeholders, enabling them to enhance e-waste management strategies and improve the effectiveness of the e-waste supply chain, contributing to a more sustainable and resource-efficient economy.
循环供应链转型是迈向可持续发展的重要一步，可实现资源优化并延长产品生命周期。电气和电子设备（EEE）行业注重终端产品的生命周期管理，将电子废物（电子垃圾）以及供应链中零部件的回收和再利用操作纳入其中。由于结构、监管和技术等方面的障碍，这种转型面临着巨大困难，在发展中经济体尤为如此。该研究通过分析社会、经济和环境可持续性因素、政府法规、技术进步以及运营挑战，确定了电子垃圾供应链系统中的关键障碍。利用多轮模糊德尔菲法，这些因素被提炼为14个关键障碍，然后通过模糊WINGS（加权影响非线性测量系统）进行优先级排序和评估。研究结果突出了关键的成因障碍，包括电子垃圾处理中非正式部门占主导地位（IIS）、政策法规无效（IPR）以及正规回收中心的电子垃圾供应不足（ISS），这些障碍严重扰乱了正规回收流程的效率。与模糊DEMATEL的对比分析揭示了某些障碍影响方面的差异，而敏感性分析证实了该模型的稳健性和稳定性。这项研究为政策制定者、政府机构和行业利益相关者提供了有价值的见解，使他们能够加强电子垃圾管理策略，提高电子垃圾供应链的有效性，推动经济向更可持续和资源高效的方向发展。
