摘要：In the modern world , pollution has dominated each facet of life. With advancement and use of modernelectronic gadgets e waste is accumulating with alarming rate. Nature finds solution to the problem of pollution throughrecycling. Reduce, reuse, recycle are the three main solutions to the problem of e- waste.E-waste comprises discarded electronic appliances, of which computers and mobile telephones are more abundant dueto their short lifespan. The current global production of E-waste is estimated to be 20–25 million tones per year, withmost E-waste being produced in Europe, the United States and Australasia. China, Eastern Europe and Latin Americawill become major E-waste producers in the next ten years. E-waste contains valuable metals (Cu, platinum group) aswell as potential environmental contaminants, especially lead (Pb), Antimony( Sb), Mercury (Hg) ,Cadmium (Cd),Nickel( Ni), polybrominated diphenyl ethers (PBDEs), and polychlorinated biphenyls (PCBs).Burning E-waste generates toxic gases such as dioxins, furans, polycyclic aromatic hydrocarbons (PAHs),polyhalogenated aromatic hydrocarbons (PHAHs), and hydrogen chloride. The chemical composition of E-wastechanges with the development of new technologies and pressure from environmental organizations on electronicscompanies to find alternatives to environmentally damaging materials. Most E-waste is disposed in landfills. Effectivereprocessing technology, which recovers the valuable materials with minimal environmental impact, is expensive. Richcountries export an major quantity of E-waste to poor countries, where recycling techniques include burning anddissolution in strong acids with very few measures to protect human health and environment.
