Sustainable Processes in the Circular Economy

Professor Alexandre Chagnes published 141 papers including 122 papers in peer-reviewed journals, 6 books including two books as Editor for Elsevier, 10 book chapters and 2 patents in the fields of electrochemistry and chemistry applied to lithium-ion batteries and hydrometallurgy. His research aims to develop the basic knowledge to remove technological barriers for the recovery of metals from primary and secondary resources. He created the French network of Hydrometallurgy PROMETHEE I 2014, which gathers 31 french laboratories. Professor Chagnes is currently the Director of the Industrial Partnerships at ENSG (Engineering School of Geology of Nancy) and Scientific Director of the LabEx RESSOURCES21 – a cluster of 9 laboratories focusing on the geochemical cycle of metals, raw material characterization, environmental and societal impact of mining, extractive metallurgy, and resource economics.
