  • Waste valorisation Laboratory

    Laboratory for the development of valorisation processes, based on hydrometallurgical, pyrometallurgical, ionometallurgical technologies and their combinations, to offer a solution to waste management problems. These actions are focused on the recovery of the elements with high value present in the waste that can be used as substitutes for conventional raw materials (metals of high economic value or critical metals, for example) or in the reuse of non-contaminated waste after the treatment of removing impurities. The processes can be performed at different levels of scale, from laboratory tests for a preliminary or more basic investigation, to validations of processes at pilot plant level.
