The construction and demolition sector is a major contributor to waste generation, prompting European and national public authorities to adopt a waste management strategy based on circular economy (CE) principles. This strategy aims to promote the reuse and recycling of construction materials. A key prerequisite for this strategy is selective deconstruction, which allows for more efficient waste recovery by separating materials based on their treatment, reuse, recycling and landfill potential. Selective deconstruction involves a value chain that includes a range of stakeholders. This paper proposes a methodology for identifying the stakeholders involved in this value chain, from project owners to waste reclamation and recycling companies. This methodology is applied to the Lille European Metropolis (France – LEM) to estimate the Deconstruction Resources Treatment Capacity of this Region (DRTCR). Finally, this capacity is analysed in relation to the volume of resources generated by deconstruction, and to the objectives set by the circular economy strategy. Results demonstrate the importance of developing selective deconstruction at a local scale, and highlight the need for investment in this sector and potential of sustainable business.
