The University of Bucharest, through CTT‑3NanoSAE, seeks to join a transnational RAMP consortium as a partner. performing work package on the sustainable recovery and electrochemical upgrading of critical raw materials, rare-earth elements and precious metals from secondary resources. It has 24 patents covering fields nanomaterials for advanced fuelcells/MFC batteries, supercap in the context of circular economy. Potential feedstocks include spent batteries, waste electrical and electronic equipment, end-of-life permanent magnets, industrial residues, process waters, mine tailings and other anthropogenic waste streams. Depletion of raw materials and their accumulation in waste, increasing pollution require new approaching to recover and reuse CRMs and rare elements to keep advances in technologies.
