Abstract

The technological advance and the factors that are leading the 4th Industrial Revolution have driven the research in the area of nanomaterials. The nanomaterials can be obtained from several processes, but a way of obtaining that deserves to be highlighted by the environmental appeal of meeting the principles of circular economy and solve problems of reverse logistics is its derivation from waste electrical and electronic equipment (WEEE). WEEE are repositories of various metals that can be recovered in the form of nanoparticles, especially copper. The project intends to establish a route to obtain copper nanoparticles from WEEE, involving sustainable hydrometallurgical routes. The proposed methodology involves the preparation of solution from selective leaching and copper purification from WEEE. In the sequence will be developed a hydrometallurgical route for the synthesis of copper nanoparticles, through a chemical reduction process. During the whole project characterization tests will be performed for monitoring, such as chemical analysis with the voltammetric analyzer, oxy-reduction potential, scanning electron microscopy. The expected results are the synthesis of copper nanoparticles, adding value to the WEEE; establish a sustainable route to obtain metals nanoparticles for later application in other technological wastes.
