Abstract: This study characterizes the composition of plastic frames and printed circuit boards from end-of-life mobile phones. • The proposed approach can improve the recovery of polymers, base/precious metals, rare earths and critical raw materials. • Suitable milling/classification strategies were set up to define specialized-pre-concentrated-streams. • Plastic frames and printed circuit boards were analyzed by electronic and chemical imaging. • Characterization was developed in a zero-waste-perspective, aiming to recover all the mobile phone materials. Palmieri, Roberta Bonifazi, Giuseppe Serranti, Silvia, E-mail: • A recycling oriented characterization of end-of-life mobile phones was carried out. traditional and classical) could dramatically improve recycling strategies set up, as well as final products recoveryĮnergy Technology Data Exchange (ETDEWEB) Results showed as the combination of both the approaches (i.e. hyperspectral imaging in short wave infrared field) techniques, with reference to frames and printed circuit boards. scanning electronic microscopy combined with microanalysis and Raman spectroscopy) and innovative (e.g. To reach this goal, end-of-life mobile phone derived wastes have been systematically characterized adopting both “traditional†(e.g. A combination of electronic and chemical imaging techniques was thus examined, applied and critically evaluated in order to optimize the processing, through the identification and the topological assessment of the materials of interest and their quantitative distribution. Correct handling of such a waste is essential for its further “sustainable†recovery, especially to maximize the extraction of base, rare and precious metals, minimizing the environmental impact of the entire process chain. ![]() ![]() Highlights: • A recycling oriented characterization of end-of-life mobile phones was carried out.
