The European economy is surprisingly wasteful and continues to operate a take-make-dispose system. Addressing this challenge requires moving from a centralizing and top-down logic of waste management to territorial approaches integrating reuse and repair activities and involving local stakeholders. To do so, living labs are a relevant approach to support the transition towards territorial repair and reuse networks. The purpose of this paper is to question how living lab thinking can integrate the development of such repair and reuse networks.

This paper first explores literature on transition design, living labs and repair and reuse activities. Secondly, it examines the design and deployment of a multi-level repair and reuse oriented living labs: (1) at the product level, it supports the participants in both learning and experimenting the basic stages in repair/upcycling practices; (2) at the repair workshop level, it helps imagine the implementation of a repair workshop and its business model, and (3) at the territorial level, it stimulates new synergies based on territorial metabolism of repair and reuse networks. A qualitative analysis on the experiment is then developed around five different objectives: (i) to strengthen the repair and reuse culture in order to (ii) collectively imagine (iii) territorialized repair and reuse networks with (iv) high social and environmental values and (v) considering how a decision taken at a system level can affect other levels, This research contributes to the transition design, developing intermediary tools to support the co-creation and/or evolution of system structures of production-consumption based on repair and reuse grassroots initiatives at the territorial level.

欧洲经济出人意料地浪费，并继续运行一种“采取-制造-处置”系统。应对这一挑战需要从废物管理的集中和自上而下的逻辑转变为整合再利用和修复活动并让当地利益相关者参与的地域方法。为此，生活实验室是支持向区域修复和再利用网络过渡的相关方法。本文的目的是质疑活体实验室思维如何整合此类修复和再利用网络的开发。

本文首先探讨了有关过渡设计、生活实验室以及维修和再利用活动的文献。其次，它检查了一个多层次的维修和再利用导向生活实验室的设计和部署：（1）在产品层面，它支持参与者学习和试验维修/升级实践的基本阶段；(2) 在维修车间层面，它有助于想象维修车间的实施及其商业模式，以及 (3) 在区域层面，基于维修和再利用网络的区域代谢激发新的协同效应。然后围绕五个不同的目标对实验进行定性分析：
