Electronic waste (E-waste) can be considered as challenging solid waste streams especially in some developing countries, including Iran. Several alternatives for collecting and processing E-waste have been developed and applied throughout the world. In this research, a model was developed according to fuzzy-AHP approach for the evaluation of different alternatives for E-waste's collection and processing in Tehran, Iran. Three alternatives for processing section (including recycling, exporting, landfilling) and three alternatives for collection section (door-to-door, special event, permanent drop-off) were studied in terms of different economic, social, technical, and environmental criteria. To establish a database in the current research, a questionnaire survey was performed and then the relative importance of each alternative in terms of each criterion was evaluated. The obtained results indicated that in the section of collection and processing of E-waste, permanent drop-off and recycling have the highest priorities among studied alternatives, respectively. Also, economic and environmental criteria were determined as the most significant ones in collection and processing sections, respectively. Furthermore, the developed model can be considered as a practical tool that will help the decision makers to determine the most appropriate E-waste management alternatives when diverse criteria are partially or completely in conflict.
电子废物（E-waste）可以被视为具有挑战性的固体废物，特别是在一些发展中国家，包括伊朗。为了收集和处理电子废物，已经开发并应用了几种替代方法。在这项研究中，根据模糊层次分析法（fuzzy-AHP）为伊朗德黑兰的电子废物收集和处理的不同替代方案建立了一个模型。根据不同的经济、社会、技术和环境标准，对处理部分（包括回收、出口、填埋）的三种替代方案和收集部分（上门、特别活动、永久丢弃）的三种替代方案进行了研究。为了在当前的研究中建立一个数据库，进行了问卷调查，然后根据每个标准评估每个替代方案的相对重要性。结果表明，在电子废物的收集和处理部分，永久丢弃和回收在研究的替代方案中优先级最高。此外，经济和环境标准分别被确定为收集和处理部分中最重要的标准。此外，所开发的模型可以被视为一个实用的工具，当各种标准部分或完全冲突时，将帮助决策者确定最合适的电子废物管理替代方案。
