摘要

This study has investigated the major barriers to the successful implementation of Construction and Demolition Waste (CDW) management and suggested effective strategies for managing CDW. This study used a mixed-method approach combining quantitative and qualitative techniques. It started by identifying major barriers through a literature review and an on-site preliminary survey. A questionnaire survey was constructed to identify the most prominent barriers, and the perceptions of respondents were analyzed using SPSS and the Relative Importance Index (RII) index. After that, face-to-face interviews were conducted among the construction experts to suggest effective policies to manage CDW. The interview results were analyzed using thematic analysis in NVivo software. The quantitative analysis has indicated that “Workers lack training in healthcare and waste handling (E6-RII 0.949),” “Insufficient attention given to waste reduction in building planning and design (I3-RII 0.948),” and “Difficulty in implementing existing regulations in practice (L2-RII 0.946)” are the most influential barriers. Furthermore, to eliminate those barriers and manage CDW effectively, the construction experts have indicated some strategies including regulatory enforcement, stakeholder collaboration, etc. This investigation aims to capture the overall waste reduction landscape and propose key waste management strategies tailored to the Bangladeshi construction sector.
