Towards a circular economy... of proximity?
This research project aims to measure the territorial impact of waste management based on the concepts and methodologies relating to ecological footprint, environmental footprint and urban metabolism. Reflections on the notion of proximity will make it possible to propose an analysis in terms of the spatial footprint of waste management on an empirical basis. We will then be able to highlight the competences of the territorial actors in the application of this principle of proximity, considering the techno-economic realities of the waste management. Taking into account the flow of materials in a variable geometry proximity will thus play on the environmental and socio-economic impacts of waste management.
A common methodology is applied to the three study cities (Le Mans, Rennes and Marne-La-Vallée) to build indicators to identify the area needed for an urban entity to treat (recover and dispose of) its waste. These results will be set against the local public policies of waste planning and more particularly of their spatial dimension. It will be understood that it is the articulation between the effective waste management territories and the planning territories.
