Seeking industrial synergies in the French Chemical Valley territory: a methodological approach for decision support
The Chemical Valley in France, a territory composed of various industrial platforms, is facing sustainability challenges. These business parks are located in the vicinity of strategic resources (water networks, pipeline networks). Their organisation allows the pooling of services, equipment and resources. Industrial ecology reveals existing and potential industrial synergies. Environmental management services within companies include facility and employee safety, waste management and effluent treatment; however, they do not develop local trade. The aim of the research conducted on an industrial consortium is to create and strengthen synergies between willing industrial entrepreneurs by testing various decision support tools. The proposed methodology in industrial ecology consists in identifying the various flows, defining collective action strategies, then comparing synergy scenarios using a multi–criteria analysis (acid–base exchange, wastewater sludge valorisation).
