Dr. Guillermo Pozo is a senior researcher in the Waste Valorization Group in Tecnalia (Spain). He did his Ph.D. (2017) in Chemical Engineering at the University of Queensland (UQ) (Australia), where he worked with bio-electrochemical systems for the recovery of rare-earth elements and acid mine drainage treatment. From July 2017 until March 2020, he worked at the Separation and Conversion Technologies section of the VITO-Flemish Institute for Technological Research, Belgium. At VITO, he developed an electrochemical process to recover metals from different waste-streams (GET-A-MET project) and the electrochemical recovery of PGMs from autocatalyst (PLATIRUS project). In January 2018, he was awarded a Marie Skłodowska-Curie Individual Fellowships (MSCA-IF) to develop a project regarding the electrochemical synthesis of magnetic nanoparticles on gas-diffusion electrodes. From June 2020, he joined TECNALIA (Spain) to work on electrochemical processes in aqueous and various ionic liquids and deep eutectic solvents. He is co‐author of >30 SCI publications wherein journals with impact factor >21 are included, co‐inventor on five patent applications.
