摘要

Construction and demolition (C&D) waste has become a major global issue, underlining the urgent need for effective waste management. Although initiatives have been taken to recover value from C&D waste, like façade components, their market success has been minimal. This study investigates the barriers restricting the use of façade components made with C&D waste in the construction industry sector. 15 barriers were validated through two stages of the Delphi method and evaluated through a multi-criteria decision-making (MCDM) framework comprising the Analytic Hierarchy Process (AHP) and Decision-Making Trial and Evaluation Laboratory (DEMATEL) in the Fermatean fuzzy set (FFS) context. Their weight significance and casual relationships were then assessed employing FFS-AHP and FFS-DEMATEL, respectively. The results suggest ‘concern over functional compatibility’, ‘absence of a reliable supply chain network’, ‘quality concerns about recycled products’, ‘absence of sustainability vision’, and ‘competitive price of new materials’ as the top five barriers restricting the use of façade components made with C&D waste. From a theoretical point of view, this study contributes by filling a research gap regarding the lack of circular practice research on C&D waste in developing façade components. From a practical standpoint, the study investigated efficient C&D waste management, which will help the construction industry sector in meeting some sustainable development goals (SDGs). Thus, it will help industrial practitioners and policymakers in formulating effective strategies and policies to effectively manage C&D waste.
