Abstract : In the last decades, many tools have been developed to understand and manage the anthropogenic cycles of materials, with different approaches. Each handles the material flows in society in different ways and each possesses its respective databases that fuel their uses. Yet there seems to be no common ground of communication between design activities and cycling activities, as well as their respective stakeholders, which hinders the information exchanges required for a proper management of discarded products (and their materials). This thesis provides two original contributions to circular product design: a tool for the integration of material circularity in product design and a framework to characterize material cycling networks. The tool is composed of a multi-criteria indicator for circular material value that is used in the Design for Material Circularity method. The framework is based on an extensive literature review enhanced by industry experts’ interviews and provides a basis for data collection and knowledge capitalization on cycling activities. The open-loop recycling networks of eight materials, from the three main material classes, are characterized using this framework (steel, aluminium, copper, precious metals, specialty metals, rare earth elements, plastics and glass). Two case studies detail the deployment of these contributions. The first focuses on the optimal choice of material and end-of-life scenario for a 1,5-litre bottle container. The second is aimed at identifying material circularity hotspots and ideal end-of-life scenarios for a vehicular lithium-ion battery pack.
