Construction and Demolition Waste (CDW) has recently received significant attention in the most developing countries, such as Iran. Since CDW generation is unavoidable, so development and implementation of an appropriate CDW management is widely recognized as an essential need. Different alternatives in CDW management have been proposed and implemented currently. In this study, a novel framework was established based on the Fuzzy Analytic Hierarchy Process approach in order to assess different CDW management alternatives in Tehran, Iran. Proposed alternatives (including landfilling, recycling, reusing, and reduction) were investigated with respect to 16 different individual criteria. The criteria were divided into four different groups, namely environmental, social, technical, economic. A database in this study was established through a questionnaire survey. The relative significance of alternatives with respect to each criterion was assessed. The obtained results revealed that reduction has the highest and landfilling has the lowest priorities. Furthermore, it was found that economic criteria have the highest and social criteria have the lowest importance among the studied criteria. Also, the proposed framework can be used as a beneficial tool that will assist decision-makers in determining the most suitable CDW management alternatives in the case of different criteria that are completely/partially in conflict.
建筑和拆除废物 (CDW) 最近在伊朗等最发展中国家受到了极大关注。由于 CDW 的产生是不可避免的，因此开发和实施适当的 CDW 管理被广泛认为是必要的。目前已经提出并实施了不同的 CDW 管理替代方案。在这项研究中，建立了一个基于模糊层次分析法的新框架，以便评估伊朗德黑兰的不同 CDW 管理替代方案。提出的替代方案（包括填埋、回收、再利用和减少）根据 16 个不同的单独标准进行了研究。这些标准分为环境、社会、技术和经济四个不同的组。本研究通过问卷调查建立了一个数据库。评估了替代方案相对于每个标准的相对重要性。结果表明，减少方案的优先级最高，而填埋方案的优先级最低。此外，研究还发现，在所研究的标准中，经济标准的重要性最高，而社会标准的重要性最低。此外，该框架还可以作为一个有益的工具，帮助决策者在不同标准完全/部分冲突的情况下确定最合适的 CDW 管理替代方案。
