I am interested in the sustainable supply of metals through its life cycle, from extraction to recycling of end-of-life products. In a circular economy context, we are developing bio-inspired extraction processes of critical metals from secondary sources. In particular, we are working with economists to evaluate the non-market values (social and environmental impacts) of the processes developed compared to traditional processes. The link with the countries of the South, major players on a global scale for the production of this resource, is an essential aspect of the projects that I am developing with the aim of supporting mining players and territories through research towards more responsible practices (social and environmental). Finally, I am strongly involved in scientific mediation actions around these subjects with schoolchildren, industrialists and the general public.
