The management of waste electrical and electronic equipment (WEEE) or electronic waste (e-waste) has become a major issue of concern for solid waste communities due to the large volumes of waste being generated from the consumption of modern electrical and electronic products. In 2003, Korea introduced the extended producer responsibility (EPR) system to reduce the amount of electronic products to be disposed and to promote resource recovery from WEEE. The EPR currently regulates a total of 10 electrical and electronic products. This paper presents the results of the application of the Delphi method and analytical hierarchy process (AHP) modeling to the WEEE management tool in the policy-making process. Specifically, this paper focuses on the application of the Delphi-AHP technique to determine the WEEE priority to be included in the EPR system. Appropriate evaluation criteria were derived using the Delphi method to assess the potential selection and priority among electrical and electronic products that will be regulated by the EPR system. Quantitative weightings from the AHP model were calculated to identify the priorities of electrical and electronic products to be potentially regulated. After applying all the criteria using the AHP model, the results indicate that the top 10 target recycling products for the expansion of the WEEE list were found to be vacuum cleaners, electric fans, rice cookers, large freezers, microwave ovens, water purifiers, air purifiers, humidifiers, dryers, and telephones in order from the first to last. The proposed Delphi-AHP method can offer a more efficient means of selecting WEEE than subjective assessment methods that are often based on professional judgment or limited available data. By providing WEEE items to be regulated, the proposed Delphi-AHP method can eliminate uncertainty and subjective assessment and enable WEEE management policy-makers to identify the priority of potential WEEE. More generally, the work performed in this study is an example of how Delphi-AHP modeling can be used as a decision-making process tool in WEEE management.
废弃电气电子设备（WEEE）或电子废物（e-waste）的管理已成为固体废物领域关注的主要问题，因为现代电气和电子产品的消费产生了大量的废物。2003 年，韩国引入了扩大生产者责任（EPR）制度，以减少电子产品的处置量，并促进从 WEEE 中回收资源。EPR 目前共监管 10 种电气和电子产品。本文介绍了德尔菲法和层次分析法（AHP）模型在 WEEE 管理工具政策制定过程中的应用结果。具体来说，本文重点介绍了应用德尔菲-AHP 技术来确定纳入 EPR 系统的 WEEE 优先级。使用德尔菲法得出了适当的评估标准，以评估将受 EPR 系统监管的电气和电子产品的潜在选择和优先级。从 AHP 模型中计算出定量权重，以确定潜在受监管的电气和电子产品的优先级。在应用 AHP 模型的所有标准后，结果表明，扩大 WEEE 清单的前 10 种目标回收产品依次为吸尘器、电风扇、电饭煲、大型冰箱、微波炉、净水器、空气净化器、加湿器、干燥机和电话。提出的德尔菲-AHP 方法可以提供一种比基于专业判断或有限可用数据的主观评估方法更有效的选择 WEEE 的方法。通过提供受监管的 WEEE 项目，所提出的德尔菲-AHP 方法可以消除不确定性和主观评估，使 WEEE 管理政策制定者能够确定潜在 WEEE 的优先级。更广泛地说，本研究中的工作是如何将德尔菲-AHP 建模用作 WEEE 管理决策过程工具的一个示例。
