Audrey Tanguy

Audrey Tanguy is a lecturer at the Ecole des Mines de Saint-Etienne in the Environmental and Organizational Engineering department, attached to the EVS (Environnement ville société) laboratory (UMR 5600). Her thesis was a France-Quebec co-tutelle (ETS Montréal and Mines Saint-Etienne). Completed in 2017, it focused on the development of a territorial approach to planning urban waste recovery channels. The methodology developed was used to guide decision support regarding the size of treatment technologies most appropriate for the study territory, taking into account various geographical factors.

More generally, her research concerns the regionalization of methods dedicated to the planning and environmental assessment (notably by Life Cycle Assessment - LCA) of industrial and territorial ecology strategies, with case studies in France and Quebec. Under the supervision of Prof. Ben Amor at the Université de Sherbrooke, she worked as a post-doctoral fellow on a methodology for regionalizing LCA applied to urban neighborhoods.

Her multidisciplinary work has also led her to take an interest in the multiscalar dimension of territorial metabolism in the waste and energy sectors. In particular, she took part in the Optimisme® project, financed by ADEME and in collaboration with economic and institutional players. The aim of this collaborative research project was to plan energy synergies within an industrial-port area.

Finally, his research into the circular economy integrates different levels of socio-technical solutions. For example, one of its recent lines of research focuses on "low-tech", or low technologies, as possible alternatives, in certain contexts, to high-tech solutions. The work of the "Viabilité Low-Tech" Collaborative Research Project (PRC), financed by the EcoSD network, has enabled an initial characterization of this approach in France.
