Abstract

E-waste plastic recycling has become an emerging pillar of sustainable construction, yet a consolidated understanding of research trends, knowledge gaps, and performance data remains underexplored. This study presents a comprehensive bibliometric review of 247 articles retrieved from the Web of Science database using the PRISMA protocol. Employing Bibliometric and VOS viewer, the analysis identifies key trends in publication growth, author impact, institutional leadership, and thematic evolution. A distinct shift from conventional metal recovery to circular economy models is evident, with India, Australia, China, and Japan leading global contributions. The Indian Institute of Technology System and CSIR India emerge as key institutions, while top dissemination channels include Journal of Cleaner Production, Waste Management, and Journal of Environmental Management. In a novel contribution, this review integrates bibliometric mapping with quantitative performance benchmarking of decentralized micro-recycling systems (DMRS) for e-waste plastics. Comparative metrics demonstrate that DMRS can reduce transportation costs by up to 70 %, lower emissions by 60–70 %, and enhance job creation and energy efficiency marking them as viable, scalable alternatives to centralized systems. Five thematic clusters and four critical knowledge gaps are identified, calling for further research in durability standards, regulatory frameworks, and scalable deployment of DMRS within circular economy frameworks.

上升趋势和现实世界的潜力：电子废塑料分散微回收系统的文献计量分析和定量基准

电子废塑料回收已成为可持续建筑的新兴支柱，但对研究趋势、知识差距和性能数据的综合理解仍未得到充分探索。本研究使用PRISMA协议对Web of Science数据库检索的247篇文章进行了全面的文献计量分析。采用文献计量学和VOS查看器，分析确定了出版增长，作者影响，机构领导和主题演变的关键趋势。从传统的金属回收到循环经济模式的明显转变是显而易见的，印度、澳大利亚、中国和日本在全球做出了主要贡献。印度技术系统研究所和CSIR印度研究所成为关键机构，而主要的传播渠道包括《清洁生产杂志》、《废物管理杂志》和《环境管理杂志》。在一项新的贡献中，本综述将文献计量学制图与分散微回收系统（DMRS）的定量性能基准相结合，用于电子废塑料。比较指标表明，DMRS可以降低高达70% %的运输成本，降低60 - 70% %的排放，并增加就业机会和能源效率，使其成为集中式系统的可行、可扩展的替代方案。确定了五个专题集群和四个关键知识缺口，呼吁进一步研究耐久性标准、监管框架和循环经济框架内DMRS的可扩展部署。
