Globally, there is interest in recycling waste electrical and electronic equipment (WEEE) plastics for transition to circular resource society and concern about substances with potential harzard in WEEE. For high-quality recycling of WEEE plastics, it is necessary to find factors that hinder recycling of the entire life of plastics and investigate hazardous substances for recycling safety. In this study, through conducting material flow analysis(MFA), 27 kt of WEEE was collected and only 3.9 % of the production was returned to plastic recycling market. To resolve this gap, further research by related organizations, including updating statistical data on the plastics, is required in addition to consideration for converting unofficial routes into official routes. For the activation of the secondary material recycling market, strict quality control is required, because some samples contained relatively high levels of PBDEs DEHP restricted under law. And it is necessary to monitor of unrestricted substance, TBBPA and Bisphenol A detected at high concentration in WEEE plastic, for the safe recycling of plastic waste.

通过物料流分析 (MFA) 和有害物质评估，增强韩国大型 WEEE 塑料的回收系统

全球范围内，人们对回收废弃电气和电子设备 (WEEE) 塑料以向循环资源社会过渡感兴趣，并对 WEEE 中具有潜在危害的物质表示担忧。为了高质量地回收WEEE塑料，需要找到阻碍塑料整个生命周期回收的因素，并调查有害物质以确保回收安全。在这项研究中，通过进行物质流分析（MFA），收集了 27 kt WEEE，只有 3.9% 的产品返回到塑料回收市场。为了解决这一差距，除了考虑将非官方路线转为官方路线外，还需要相关组织进一步研究，包括更新塑料统计数据。为了激活二级材料回收市场，需要严格的质量控制，因为一些样品中法律限制的PBDEs DEHP含量较高。为了安全回收塑料废物，有必要对WEEE塑料中检测出的高浓度非限制物质TBBPA和双酚A进行监测。
