Since 2008, South Korea has operated the Extended Producer Responsibility (EPR) system, which collects and recycles waste electrical and electronic equipment (WEEE). Although the EPR recycled 305,050 tons of WEEE in 2017, approximately 62.5% remained in the informal sector, posing potential risks to the environment. This study is intended to provide information on consumer behavior regarding the discharge of WEEE and to analyze the causality between consumer beliefs and behavior, using the theory of planned behavior (TPB) model to establish strategies for maximizing the flow of WEEE through the formal sector. In accordance with the methodology, questionnaire data were collected from 2,000 respondents, who were selected through a stratified procedure, using computer-assisted telephone interviews to investigate their behavior related to the discharge of WEEE. According to the results, about 31.50% of the respondents had disposed of WEEE in 2017, and the most frequently discarded item was a refrigerator (35.08%). Local authorities (38.95%) and take back (37.30%) were the preferred means of discarding large- and mid-sized appliances. According to the TPB analysis, norm and control beliefs for discarding WEEE through the formal sector significantly affected behavioral intention (p$\le$0.001). Furthermore, controlbeliefs directly affected actual discharge behavior (B = 1.351, p$\le 0$.001)and actual discharge routes (B = 0.846, p$\le$0.05). These results indicate that the TPB can provide political strategies for discarding WEEE through the formal sector based on the causality between consumer beliefs and actual consumer behavior.

自2008年以来，韩国一直在使用生产者延伸责任制（EPR），该系统负责收集和回收废弃的电气和电子设备（WEEE）。尽管EPR在2017年回收了305,050吨WEEE，但仍有约62.5％留在非正规部门，对环境构成潜在风险。这项研究旨在提供有关WEEE排放的消费者行为信息，并分析消费者信念和行为之间的因果关系，使用计划行为理论（TPB）模型来建立使WEEE通过正规部门流动最大化的策略。根据该方法，我们从2,000名受访者中收集了问卷数据，这些受访者是通过分层程序选择的，使用计算机协助的电话采访来调查他们与WEEE放电相关的行为。根据调查结果，2017年约有31.50％的被处理者处理过WEEE，最常被丢弃的物品是冰箱（35.08％）。丢弃大型和中型家电的首选方法是地方政府（38.95％）和收回（37.30％）。根据城规会的分析，通过正规部门丢弃WEEE的规范和控制信念显着影响了行为意图（p$\le$0.001）。此外，控制信念直接影响实际的排放行为（B  = 1.351，p$\le 0$.001）和实际排放路线（B  = 0.846，p$\le$0.05）。这些结果表明，城规会可以提供基于消费者信仰与实际消费者行为之间因果关系的，通过正规部门丢弃WEEE的政治策略。
