Abstract

China has established a nationwide formal e-waste disassembly system based on the extended producer responsibility principle. However, the system mainly focuses on material recycling while excluding the reuse of used electrical and electronic equipment (used EEE) due to the complexity of flows and transactions during the reuse stage. Recently, emerging online platforms have played an increasingly crucial role in the value chain of reuse and recycling, significantly improving the visibility of flows in these activities. This paper aims to depict the spatial structure of the used EEE and e-waste flow networks using a multi-scale analysis framework. Using spatial analysis tools in complex network analysis, we characterize cross-city reuse flows in China. A clear regional pattern of a hierarchical reuse network of notable regional hubs in certain regions in China is revealed in this analysis. The role of regulation is demonstrated in the comparison of the spatial flows in reuse and recycling. In conclusion, it is proposed that reuse should be included and emphasized in the management of waste electrical and electronic equipment in China to maximize the value of circularity.

利用平台数据分析废旧电子电气设备和电子废物的网络流动:将再利用纳入中国废旧电子电器产品回收的 EPR 系统
中国已根据生产者责任延伸原则建立了全国范围的正规电子废物拆解系统。然而,由于再利用阶段的流动和交易的复杂性,该体系主要侧重于材料回收,而不包括废旧电子电气设备(废旧 EEE)的再利用。最近,新兴的在线平台在再利用和再循环价值链中发挥了越来越重要的作用,极大地提高了这些活动中流动的可见性。本文旨在利用多尺度分析框架描述废旧电子电气设备和电子废物流动网络的空间结构。利用复杂网络分析中的空间分析工具,我们描述了中国跨城市再利用流动的特征。该分析揭示了一个清晰的区域模式,即在中国的某些地区存在一个由显著的区域中心组成的分层再利用网络。通过比较再利用和回收利用的空间流动,证明了监管的作用。总之,建议在中国废弃电子电气设备管理中纳入并强调再利用,以实现循环价值的最大化。

期刊介绍: The Journal of Industrial Ecology addresses a series of related topics: material and energy flows studies (''industrial metabolism'') technological change dematerialization and decarbonization life cycle planning, design and assessment design for the environment extended producer responsibility (''product stewardship'') eco-industrial parks (''industrial symbiosis'') product-oriented environmental policy eco-efficiency Journal of Industrial Ecology is open to and encourages submissions that are interdisciplinary in approach. In addition to more formal academic papers, the journal seeks to provide a forum for continuing exchange of information and opinions through contributions from scholars, environmental managers, policymakers, advocates and others involved in environmental science, management and policy.
