This article explores the territorialisation of the circular economy (CE) and analyses how the geographical and organised proximities of stakeholders facilitate the mobilisation of local resources for CE projects. It focuses on two local CE initiatives in Quebec (Canada) and France, for which 70 semi-structured interviews were conducted. The results highlight the importance of tangible and intangible territorial resources and demonstrate that geographical and organised proximities are crucial to the success of these initiatives. The relational dynamic between local players, stimulated by a sense of belonging and shared values, encourages commitment to CE. Thus, our study showcases the territorialisation of CE and emphasises the conditions enabling such activities to take root locally. This study has significant political implications and suggests the crucial role that local authorities must play in the deployment of CE projects.
