  1. 1. • Electronic waste (e-waste) comprises wasteelectronics/electrical goods that use or have reachedtheir end of the life.• E-waste contains valuable materials likecopper, silver, gold which can be processed for theirrecovery.• Major portion of e-waste is processed by theinformal (unorganised) sector using rudimentarytechniques such as acid leaching and open-airburning, which results in severe environmentaldamage.
  2. 2. THIS MULTI HEADED E-WASTE MONSTER HAS MANYSIDES.•Telecommunication Waste: Mobile phones, telephones,telephone exchanges wireless equipment cables andrelated scrap material.• Electrical Waste: Switches, Relays, Connectors andrelated Scrap Material.• Electronic Waste: Electronic – metal waste, PrintedCircuit Boards, E – Equipment and Machinery, IC, SocketsConnectors.• Cable Waste: PVC, Pre Insulated Copper and AluminumCable waste.• Chemical Waste: Chemical Sludge and Residue.
  3. 3. E-waste in IndiaAs per IRG (inter report gap) report, India generates about1,46,180 tons of E-waste every year.This is contributed by both house holds and corporate houses.E-waste in USABetween 1997 and 2007, nearly 500 million personalcomputers will be obsolete-almost two computers for eachperson.750,000 computers expected to end up in landfills this yearalone.
  4. 4. Sources of E-wasteSeveral electronic equipment, such as computers, monitors,printers, and scanners, contain materials suitable forreclamation and use in new products. These may includeplastic, glass, steel, aluminum, copper, gold, silver, and othermetals.Electronic products often contain hazardous and toxicmaterials that pose environmental risks if they are land filled orincinerated.Televisions, video and computer monitors use cathode raytubes (CRTs), which have significant amounts of lead.In addition, many electronic products have batteries that oftencontain nickel, cadmium, and other heavy metals. Relays andswitches in electronics, especially older ones, may containmercury.
  5. 5. Recycling workers manually dismantle most electronic equipment and sort out valuable commodities that are sold to various recyclers.CRTs ready to be "crushed"for recycling. HMR(Hazardous MaterialRegulation) accumulatesquantities like this eachweek.
  6. 6. The CRT crusher is completely self-contained in a transportable shipping container.Crushed CRT glass, coatedwith lead, ready forprocessing by a lead smelter.
  7. 7. Other components fromelectronicsare separated and sold ascommoditiesto various recyclers.
  8. 8. Benefits Of Recycling 100% landfill diversion Recovery of raw materials from e-waste Use of domestic markets for recycled raw materials Competitive pricing for recycling services Arrangements for collection and removal of equipment from your premises Advice on how best to package waste for most secure and economical transportation On site visit to evaluate customer needs Assistance with special waste collection days
