Household waste source separation substantially reduces the amount of rubbish sent to landfills and incinerators. It enables value recovery from useful waste for transitioning to a more resource efficient and circular economy. Confronted by the severe waste management problems, China recently implemented its most strict compulsory waste sorting program in big cities to date. Despite the failures of waste sorting projects in China in the past, it is unclear what the implementation barriers are, how they interact, and how they can be overcome. This study addresses this knowledge gap through a systematic barrier study involving all the relevant stakeholders in Shanghai and Beijing. It uncovers the complex interrelationships between barriers using the fuzzy decision-making trial and evaluation laboratory (Fuzzy DEMATEL) method. "Hasty and inappropriate planning" and "lack of policy support at the grassroots level", two new barriers that are not reported in the literature, are found to be the most influential barriers. Policy implications are discussed based on the study findings to inform the policy deliberations on the implementation of compulsory waste sorting.
生活垃圾源头分类大大减少了送往垃圾填埋场和焚烧炉的垃圾量。它可以从有用的废物中实现价值回收，从而向更具资源效率和循环经济转型。面对严峻的垃圾管理问题，中国最近在大城市实施了迄今为止最严格的强制性垃圾分类计划。尽管中国过去的垃圾分类项目失败了，但不清楚实施障碍是什么，它们如何相互作用，以及如何克服这些障碍。本研究通过系统的障碍研究，涉及上海和北京的所有相关利益相关者，解决了这一知识差距。它使用模糊决策试验和评价实验室 (模糊 DEMATEL) 方法揭示了障碍之间的复杂相互关系。“仓促和不适当的规划”和“基层缺乏政策支持”这两个在文献中没有报道的新障碍被发现是最具影响力的障碍。根据研究结果讨论了政策含义，为强制性垃圾分类实施的政策审议提供信息。
