Circular economy (CE) is nowadays the new business model to follow. To support this implementation, several tools exist allowing collaboration between actors. Usually, these tools are based on material flux analysis, market waste or flow exchanges. Some CE strategies, sometimes, struggle to get off the ground or may not be lifelong. Indeed, a successful strategy is a long-term strategy. Thus, how to characterize the potential of territories to implement long-term CE strategies? NympheA and Mines Saint-Etienne developed a framework for analysing geographic areas in order to characterize, a priori, their potential for the implementation of CE strategies. The aim of this methodology is to help decision-makers in their regional planning and to initiate operationally an CE approach with companies. It is based on three complementary steps, each of which enables the macro, meso and micro economic levels of the area to be characterized. Each level is based on criteria relating to social, organizational, economic, legal, geographical, physical, or environmental dynamics. The so-called ADALIE© method enables the data to be processed and the results to be presented with spider graphs, a SWOT matrix and justifications. This allows a better understanding and appropriation of the specificities of each of the three study scales. Applied today to around twenty territories, a hundred business areas and with 500 companies, ADALIE© has proven its effectiveness. It made it possible to initiate and consolidate IE approaches by bringing together the following four sustainability factors: governance, economic model, operationality and communication.
