SADéMMaR

Over the entire life cycle of a capital good, the production stage has the greatest impact on climate change, the depletion of mineral and fossil resources, acidification and respiratory effects, and the emission of inorganic pollutants. To reduce this impact, the circular economy consists in implementing various cyclical processes, including maintenance processes. Despite a favorable legal context, the practice of repair is not in the majority among the French: an ADEME survey shows that 85% say they have considered repairing their goods, but only 38% firmly affirm this, that for 63%, a breakdown remains sufficient reason to replace the equipment, and that for a product that has broken down, only 36% of respondents on average repair it and 54% on average replace it. The obstacles to this "repair culture" are many: technical, sociological, financial and economic. The project aims to overcome these obstacles through a multi-disciplinary approach, adapting the scientific methods required for each stage of the detection/diagnosis/repair process to the characteristics of the capital goods and the profiles of the players involved in a repair process in which the citizen is the key player. An initial study will be carried out of the system of players involved in this process (manufacturers, distributors, repair professionals, social economy players such as repair cafés, fablabs, etc.), in order to understand their behavior and identify the various obstacles. Solutions (tools, methods, information systems) will then be proposed to support players in their decision to opt for repair rather than replacement, and to implement this repair. These solutions will be inspired by those proposed by the scientific community for industrial equipment maintenance (equipment modeling based on statistical signal processing tools and artificial intelligence methods). The proofs of concept corresponding to these solutions will be submitted to representatives of the various stakeholder categories and improved in line with their feedback. Finally, the value chains corresponding to traditional and emerging repair systems will be compared, and the mechanisms (financial, organizational, legal, etc.) that would make certain innovative repair models viable will be deduced. The SADéMMaR project is part of a process of regional reappropriation of production, not of capital goods, but of the services rendered by these goods. The aim is to ensure that equipment manufactured thousands of kilometers away has a much longer lifespan than expected. Helping to extend the lifespan of goods that have already been manufactured provides a number of services to the public: not only does it enable them to enjoy the functions provided by the goods for longer, but it also reduces their carbon impact and the health problems that can result. The project also contributes directly to the development of resilient economic models such as the circular economy, the economy of functionality, and the collaborative economy.
