The reuse of Waste Electrical and Electronic Equipment (WEEE) is deemed the best end-of-life option in terms of the environmental impact and socio-economic benefits. Taking this cue, this paper applies a systematic literature review to map the existing knowledge base to present the major and emerging themes of the reuse assessment of WEEE. In all, 12,216 articles published from 2005 to 2019 in the Web of Science, ProQuest, and Google Scholar are collected, from which 331 articles are shortlisted for review. The shortlisted articles are divided into two sub-periods 2005-2014 and 2015-2019 to draw out the development of the research themes and the contribution of the recent research articles to the literature on WEEE reuse assessment. Bibliographic coupling combined with keyword analysis is performed using SciMat and VOSViewer. The results inform that the major ongoing themes are Consumer behaviour towards use, disposal, collection, reuse, repair and recycling of WEEE; Assessing the potential of WEEE for reuse; Product recovery strategy and market analysis for WEEE remanufacturing; and Material flow analysis of WEEE in circular economy. The research themes of Informal WEEE management in developing countries; Impact of government subsidy on WEEE management; and Product service system and circular economy deserve further attention. In the articles reviewed, mobile phones and computers are extensively studied for WEEE reuse assessment followed by refrigerators and televisions. Assessing the environmental impact and legal aspects of WEEE reuse, cross-border movements and flow in secondary markets, policies and regulations on the purchase of reprocessed WEEE, and the reprocessing and revenue made by the informal sector in developing countries are possibilities for future research.
就环境影响和社会经济效益而言，废弃电子电气设备（WEEE）的再利用被视为最佳的报废处理选择。受此启发，本文运用系统文献综述来梳理现有知识库，以呈现WEEE再利用评估的主要和新兴主题。总共收集了2005年至2019年发表在科学网、ProQuest和谷歌学术上的12216篇文章，从中筛选出331篇文章进行评审。入围文章分为2005 - 2014年和2015 - 2019年两个子时期，以梳理研究主题的发展以及近期研究文章对WEEE再利用评估文献的贡献。使用SciMat和VOSViewer进行文献耦合并结合关键词分析。结果表明，当前的主要主题包括消费者对WEEE的使用、处置、收集、再利用、维修和回收的行为；评估WEEE的再利用潜力；WEEE再制造的产品回收策略和市场分析；以及循环经济中WEEE的物质流分析。发展中国家的非正规WEEE管理、政府补贴对WEEE管理的影响以及产品服务系统和循环经济等研究主题值得进一步关注。在所评审的文章中，手机和电脑在WEEE再利用评估方面得到了广泛研究，其次是冰箱和电视。评估WEEE再利用的环境影响和法律方面问题、二手市场中的跨境流动和流量、关于购买再加工WEEE的政策法规以及发展中国家非正规部门的再加工和收入情况，都是未来研究的方向。
