Current industrial practices, supported by an unsustainable economic growth and technological innovations, are leading to a "throwaway" era leading to inefficient use of natural resources and social inequity. The reuse and repair of products are priority strategies for a radical reduction of the environmental and social impact of our production and consumption. It consequently questions the paradigm of traditional economic growth. The transition to repair and re-use activities requires going beyond the technical aspect of waste management to embrace a citizen and territorial logic. In this paper, we submit the hypothesis that through "living labs", that is to say, citizen, collaborative and experimental workshops, it is possible to structure communities of practice and to improve the recognition of repair and reuse activities both for citizens, political and economic actors. On the one hand, the aim is to understand how to stimulate the collaboration of heterogeneous actors through experiments in the context of reuse / repair and upcycling oriented living labs. On the other hand, the objective is to collectively participate in the emergence of territorial repair networks, with the objectives of reducing environmental impacts while creating social links and questioning development models. For that, we expose the protocol developed to structure the living labs as well as the some qualitative results.
