Özet
Construction and demolition waste (CDW) represents one of Europe’s largest materials flows and a critical challenge for achieving circularity in the built environment. Drawing on comparative case studies from Latvia, Estonia, Greece, Cyprus, Slovenia, Romania, and Turkey, this paper analyzes how diverse CDW management models: centralized recycling hubs, on-site demolition processing, closed-loop manufacturing systems, public-led circular construction initiatives, and digital or technology-enabled waste prevention strategies influence material recovery outcomes, environmental performance, and market dynamics. Using a structured cross-case analytical framework, the study compares technological, regulatory, and operational features across cases to understand how collection, sorting, and processing systems shape circularity potential. Results demonstrate that advanced automated sorting, integrated value-chain models, and digital tools can substantially increase landfill diversion rates, reduce CO2 emissions, and preserve virgin resources. However, persistent barriers including insufficient market demand for secondary materials, lack of end-of-waste criteria, regulatory inconsistencies, and cultural resistance, limit broader uptake. Stakeholder insights further highlight the role of political incentives, economic competitiveness, and technological readiness in enabling or constraining CDW circularity. The findings contribute to a clearer understanding of how European CDW sorting and processing practices can support a high-value circular construction transition and identify priority areas for policy and industry action.
