Abstract: With growing numbers of construction sites, aggregate supply in the Ile-de-France region (Paris and the surrounding area) will be a major issue in the coming years. This means that dialogue is needed between stakeholders to build and evaluate scenarios together for the future in this area of aggregate supply and waste reclamation. This work had the goal of describing, analysing and discussing the first evaluation of potential scenarios from the thematic and methodological standpoint, asking questions about issues of sustainable circularity in the aggregate sector in Ile-de-France. In the state of the art, tools for objective evaluation are being widely developed in the sector, whereas tools for subjective evaluation remain largely unexplored, hence this work. As results, we have given structure to what challenges will be raised for a circular economy for supplying aggregates in Ile-de-France. However, the challenges are not even for all of the issues, scenarios and impacts.
