In the worrying context of the future of plastics and their ecological impacts, Stéphane Bruzaud will talk about a very promising family of polyesters: polyhydroxyalkanoates. He specialises in the study and engineering of biopolymers, from their production from renewable resources to their end-of-life. His activities concern the development of virtuous approaches for the elaboration (through the use of biotechnology processes from co-products, for example) and for the formulation of bioplastics (mixtures between biopolymers and/or incorporation of natural fillers). He has also led several programmes or theses on the recycling and (bio)degradation of these polymers in different environments (photo-oxidation, gamma irradiation, soil, sea water, etc.). He is also interested in the pollution of the terrestrial and marine environment by microplastics. In this context, it has developed innovative methodologies for extracting and characterising plastic microparticles contained in different environments (seawater, sediments or soil). All the research carried out in Prof. Stéphane Bruzaud’s group illustrates and confirms the interest in developing more environmentally friendly materials that can constitute a virtuous and realistic alternative to the plastics usually used.

Stéphane Bruzaud is involved in numerous national and international collaborative projects (H2020, Interreg, Ministry of Ecological Transition, CNRS, ADEME, Région Bretagne, TASSILI, PROFAS B+, etc.) but also in contractual research in direct link with companies (L’Oréal, Total, Bic, Lessonia, Silab, Europlastiques, Séché Environnement, Triballat-Sojasun, Elixance, etc.) He is also a scientific partner of several NGOs, including the Tara Ocean Foundation and Expedition MED.

Finally, after having directed the Grand Ouest section of the Groupe Français des Polymères (GFP) for 6 years, he is now a member of the GFP Board of Directors. He is a founding member and a member of the Scientific Council of the CNRS Research Group “Polymers and Oceans”, which aims to federate the scientific community around marine pollution by plastics.
