| contents | <p><strong><span>ABSTRACT</span></strong></p> <p><span>Electronic Waste (E-waste) is a generic term referring to all the end-of-life electronic appliances (like computers, laptops, audio and video products, refrigerators, freezers, mobiles phones, etc. and is reported as the rapidly expanding waste stream around the globe. According to Global E-waste Monitor 2024, of the 62 billion kg of E-waste generated globally in 2022, only 13.8 billion kg has been formally collected and properly recycled. A major portion is finally ending up in landfills. Improper disposal of E-waste is a major cause of various diseases due to the exposure to toxic heavy metals like lead, cadmium, mercury, and organic compounds like halogenated flame retardants, biphenyls, phthalates etc. E-waste is the largest secondary source of precious metals. Studies indicate that nearly 3% of gold and silver, 13% of the palladium and 15% of cobalt mined each year is used in the manufacturing of electronics. Therefore, the recovery of these metals from E-waste by creating a circular economy approach has great importance in terms of sustainability. Despite the new rules introduced to safely process this hazardous waste, it still exists as a potential threat to health and environment especially in developing countries. A comprehensive analysis of various approaches as well as development of a more effective process for the recovery of metal values from E-waste in terms of better selectivity and efficiency is highly demanding owing to its large volume generation, price value and hazardous nature. Herein we are presenting a review on the metal recovery processes from E-waste that happened in the last decades.</span></p> |
