Data Driven Decision Support Framework for Product Level Reuse Prioritisation and Barrier Diagnosis

Abstract: This paper proposes a three-stage workflow to prioritise reusable building product groups in Dutch demolition outflows, addressing the gap between impact potential and implementation feasibility. Stage 1 screens 139 groups using an impact proxy combining mass outflow and the environmental cost indicator, shortlisting ten candidates. Stage 2 applies a five-criteria multi-criteria analysis with weights from eight experts using the Best–Worst Method, where supply–demand balance dominates (0.296) and sustainability ranks lowest (0.137). Stage 3 links ranking to barrier diagnosis through a masonry case, identifying contamination, certification, and coordination challenges. The workflow supports identifying high priority product groups for early-stage reuse planning.
