Description Electronic waste (E-waste) which consists of old, end-of life, discarded electrical and
electronic equipment’s (EEE), is the most rapidly growing MSW stream worldwide. The toxic
and hazardous materials present in it can lead to severe environmental and occupational
hazards, if not handled properly. However, presence of significant quantity of valuable
recoverable material makes it a potential secondary resource for metal extraction. Composition
of E-waste is complex with 38% ferrous material, 28% non-ferrous material, 19% plastic, 4%
glass, 11% other (wood, rubber, ceramic, etc.). Although the precious materials are only 1% by
weight, it accounts to nearly 80% of the total intrinsic value. Around $ 21 billion of Au and Ag
are used in various EEE per annum.Along with precious metals it also contains various rare
earth metals such as Platinum, Gallium, Indium, Lithium, etc. Primary metal extraction from
mining has significant negative environmental impact due to substantial natural resources
consumed and low recovery efficiency; comparatively extraction from E-waste is 50 times
greater which is much more economical with lesser ecological foot printand the energy savings
are considerable: aluminium 95%, copper 85%, iron and steel 74%, plastics 80%. This is the reason why E-waste recycling which is also called as “Urban Mining” can facilitate in
sustainable management and conservation of rapidly depleting natural resources.
