Metal recovery in mobile phone waste: Characterization of metal composition and economic assessment through shredding and screening processes.

Recycling mobile phones, including their batteries, has become crucial for environmental sustainability, but traditional manual dismantling methods are time-consuming and inefficient. This study aims to improve the pre-processing of end-of-life mobile phones (EoL-MPs) through industrial shredding and sieving, minimizing manual labor. For the first time, a sample of 850 mobile phones in an interval of 20 years (2000-2020) was collected and analyzed before and after being processed.
