摘要

The growing volume of discarded mobile phone waste highlights the urgent need for better plastic recycling technologies. This study looks into density-based separation for recovering various plastic types from shredded mobile waste. This study  treated 650 g of mobile plastic using salt solutions of various densities and successfully separated plastic fractions such as ABS (41.56%), PC (21.56%), PET (10.29%), and other plastics (26.59%). This study not only demonstrates remarkable technical precision but also offers a promising pathway to address the complex problem of electronic waste recycling. By minimizing chemical interventions and maximizing material recovery, this approach embodies the principles of sustainable materials management. The research illuminates the potential for scalable, environmentally conscious recycling technologies that could significantly mitigate the ecological footprint of electronic waste.
