Abstract : Circular Economy is at the heart of the new environmental policies in France, in Europe and in the rest of the world. It consists in changing the global production apparatus such that its environmental footprint is minimized, by Reducing, Recovering, Recycling and Repurposing. Recent research emphasizes maintenance is one of the most effective tools to increase the lifespan of technical objects and thus minimizing interaction with the environment. Knowing this, the question is: How to efficiently schedule maintenance in order to improve the economic and environmental sustainability of a technical object? This work aims to provide tools for optimizing maintenance schedules within the framework of Circular Economy. Based on a review of the literature on Circular Economy and Scheduling Theory, we present a Multi-Objective Mixed Integer Linear Program (MILP) for optimizing maintenance planning alongside with a heuristic approach. Then, the specific application case of Laundromat washing machines is studied. Experiments are then realized and the results are presented and analyzed. Circular economy aware production/maintenance plannings are obtained for specific weightings of the objectives and provide decent results even on large instances, yet some specific cases yield mixed results and potential improvements and further developments are suggested.
