Sophie CARLI-OMONT, a doctoral student at the I2M laboratory in Bordeaux but employed by AMVALOR at the Chambéry institute, will defend her thesis, funded by BPI France as part of the FUI-22 call for projects, on Wednesday, December 8.
It focuses on developing a methodology for assessing and controlling the health and environmental impacts of polymers intended for use at sea: application to oyster farming.
Summary
This work is part of the development of a new plastic oyster farming component. Its objective is to propose a methodology specifically developed for the eco-design of plastic materials used in oyster farming, with a view to ensuring: 1 – Their safety for oysters, oyster consumers, and marine ecosystems, 2 – Their durability, or maintenance of their physical integrity over time, in order to optimize their useful life and slow their degradation in the environment, 3 – Their recyclability after use, with a view to ensuring their integration into a circular economy. The development of this methodology was organized around a general risk management framework, comprising five stages in which scientific, toxicological, and ecotoxicological data, as well as the most relevant decision-making methods and tools, were used, adapted, or developed to identify, assess, and control potential hazards. To facilitate its integration into an eco-design approach, the technical and economic expectations and the role of each player in the material value chain were taken into account. The implementation of this methodology led to the selection of two polymer matrices and two formulations. The three experimental materials obtained were tested in situ as part of a cultivation cycle experimenting with the prototype of the production system under development. The initial results suggest that recyclability, durability, and levels of substance emissions into the environment can be controlled. Developed for oyster farming, this methodology, which is based on establishing scenarios for the fate, exposure, and effects of polymer components, should be adaptable to other uses.
