Abstract |
Urbanization causes massive flows of construction materials and waste, which generates environmental impacts and land-use conflicts. Circular economy strategies at a local scale and in coordination with urban planning could respond to those issues. Implementing these strategies raises challenges as it requires a better knowledge of flows and their space-differentiated drivers. This article focuses on the case of the Paris region (Ile-de-France) in 2013. Construction materials inflows and outflows to and from anthropogenic stocks of buildings and networks are estimated and located though a bottom-up approach based on the collection and processing of geolocalized data. Flow analysis focuses on the relationship between urbanization and flows with a view to establishing context-specific circular economy strategies. Results show that regional inflows of construction materials to stocks in 2013 reach between 1.8 and 2.1 t/capita while outflows are between 1.0 and 1.5 t/capita. Both inflows and outflows are mainly driven by building construction and demolition as well as by road renewal. The region is composed of three sub-urban areas and flows per capita in the dense central city of Paris are significantly lower than in the low-density outskirt area of Grande Couronne (GC). Road renewal accounts for a larger share of flows in GC. Future research will address methodological limits. |
