Around 57.4 million metric tons (Mt) of electrical and electronic waste (e-waste) was generated worldwide during 2021, which would surpass the weight of the Great Wall of China. Asia contributed the highest generation (24.9 Mt), followed by Americas (13.1 Mt), Europe (12 Mt), Africa (2.9 Mt), and Oceania (0.7 Mt) in 2019, showing a dreadful global scenario of e-waste. If incumbent 3-4% global annual surge (i.e., 2 Mt annually) in generation is not controlled, it would cross 74.7 Mt by 2030, and 110 Mt by 2050, and three earths would be needed by then. With legislative gaps, business motives, socioeconomic reasons and other, over 5.1 Mt e-waste saw transboundary movement and waste trafficking in 2019 from developed to developing countries, mainly in Asia and Africa (1.8 Mt in controlled and rest 3.3 Mt in uncontrolled manner), despite norms of the Basel Convention, which prevents such activities. Main problems with e-waste are their linear style of business model but with circular economy, raw materials used to produce items are processed or recycled at end-of-shelf life, cutting necessities of unnecessarily newer products and environmental pollution. The e-waste management can be made sustainable by: a) strictly implementing e-waste management legislations; b) raising public awareness about their health and environment impacts; c) making extended producer responsibility mandatory; d) formalizing recycling units. Proper repairing or recycling is crucial to maintain circularity within precious heavy metals such as copper, gold, silver and other inherent in e-waste. Currently, non- environmentally safe management (ESM) techniques such as manual dismantling, melting, open burning, untested chemical dissolution or leaching are often practiced by informal e-waste handlers in developing nations to recover these, which potentiate release of toxic leachate, fumes and persistent organic pollutants into environment and damage global health and planetary environment. About 2 tons of carbon dioxide emission can be reduced by properly recycling one ton of e-waste, which helps minimize global warming. Still, out of 53.6 Mt global e-waste generated in 2019, only 17% (i.e., 5.3 Mt) was recycled using ESM techniques. If environmentally sound transboundary movement is regulated to pool the global e-waste into a centralized channel under strict scrutiny and vigilant leadership of the Basel Convention and the United Nations, it would contribute to global health and planetary environment by promoting resource efficiency, circularity and sustainability.
