  • 3. "E-waste" is a popular, informalname for electronic productsnearing the end of their "usefullife. "E-wastes are considereddangerous, as certaincomponents of some electronicproducts such as discardedcomputers, televisions, VCRs,stereos, copiers, fax machines,electric lamps, cell phones, audioequipment and batteries ifimproperly disposed can leachlead and other substances intosoil and groundwater. Many ofthese products can be reused, orrecycled in an environmentallysound manner so that they areless harmful to the ecosystem.
  • 4. Technology is changing and people change their electronicproducts like mobile phones , and other electronic gadget,second-hand electronic equipment are dumped. Where? Idont know .. but its all waste - " e-wasteRecyclable electronic waste is sometimes furthercategorized as a "commodity" while e-waste which cannot bereused is distinguished as "waste". Both types of e-wastehave raised concern considering that many components ofsuch equipment are considered toxic and are notbiodegradable.
  • 5. How is it effecting LIFE?• Computer wastesthat are land filledproducescontaminatedleachates whicheventually pollutethe groundwater.
  • 6. •Acids and sludgeobtained from meltingcomputer chips, ifdisposed on the groundcauses acidification ofsoil.
  • 7. •Incineration ofe-wastes can emittoxic fumes andgases, therebypolluting thesurrounding air
  • 8. • Disposing of e-waste is notonly affecting human but evenpoor animals are suffering.
  • 9. Health effects of certain constituents in e-wastes lead Used in… CRT screens Drained lead Batteries Printed wiring boards inside computers Ill effects.. oDamage to central and peripheral nervous systems, blood systems and kidney damage oAffects brain development of children.
  • 10. beryllium Used in… MotherboardsIll effects..olung canceroInhalation of fumes and dust. Causes chronicberyllium disease or beryllicosisoSkin diseases such as warts
  • 11. mercury Used in… Fluorescent lamps LCD display screens with fluorescent lighting Mercury-wetted switches and some alkaline batteries.Ill effects…oChronic damage to the brain.oRespiratory and skin disordersdue to bioaccumulation in fishes.
  • 12. cadmium Used in… Rechargeable batteries Printer inks and toners Photocopying machinesIll effects…oAccumulates in kidney.oCauses neural damage.
  • 13. Used in… BARIUM Spark-plug electrodes and in vacuum tubes as drying and oxygen-removing agents. Fluorescent lamps To make paint, bricks, tiles, glass and rubberIll effects… Short term exposureoMuscle weaknessoDamage to heart, liver and spleenFact:Study by the Chittaranjan National CancerInstitute, Kolkatta, found that people in Delhiare about twice as likely to suffer from lungailments as those in the countryside due tothe huge amount of e-waste generated.
  • 14. FACTS The situation is alarming as Indiagenerates about 1.5 lakh tones of e-wasteannually. Bangalore may be generating 10,000tones to 15,000 tones of e-waste everymonth, according to industry sources.
  • 15. Guiyu, Hong Kong athriving area of illegal e-waste recycling is facingacute water shortages due tothe contamination of waterresources.
  • 16. While the world is marvelingat the technological revolution,countries like India are facingan imminent danger. E-waste of developed countries,such as the US, dispose theirwastes to India and other Asiancountries. Major reasons for exports arecheap labour. Recycling a computer costsUSA and Europe 20 US dollarswhereas India only 2 USdollars.
  • 17. Rate of growth of e-waste!!
  • 18. Our world will be e-waste within no time
  • 19. ELECTRONIC WASTE MANAGEMENTIt is estimated that 75% of electronic items are stored due touncertainty of how to manage it. These electronic junks lieunattended in houses, offices, warehouses etc. and normally mixedwith household wastes, which are finally disposed off at landfills.This necessitates implementable management measures. BUT THIS HAS A SOLUTION …..
  • 20. YES we can… THROUGH…Recycling for e-waste is called e-cycling
  • 21. Block diagram for e-cycling E-WASTE
  • 22. How e-waste is obtained
  • 23. The mantra of " REDUCE REUSE RECYCLE "
  • 24. reduce your generation of e-wastethrough smart procurement and good maintenance. Can u just believe
  • 25. reuse still functioning electronic equipmentby donating or selling it to someone who can still use it GIVE YOUR ELECTRONICS BELIEVE IT OR NOT!!! A SECOND CHANCE AT LIFE
  • 26. recycle those components that cannotbe repaired. Waste prevention is perhaps more preferred to any otherwaste management option including recycling.
  • 27. Government measures Governments should enforce strict regulations againstdumping e-waste in the country by outsiders. Governments should enforce strict regulations and heavyfines levied on industries, which do not practice waste preventionand recovery in the production facilities. Governments should set up regulatory agencies in eachdistrict Governments must encourage research into the developmentand standard of hazardous waste management, environmentalmonitoring and the regulation of hazardous waste-disposal. In Bangalore, there are NGOs like Saahas & EWA who areworking for e-waste management.
  • 28. Industrial participationIn industries management of e-waste should begin at the point ofgeneration. This can be done by waste minimization techniquesand by sustainable product design. Waste minimization inindustries involves adopting: record management, Production-process modification, Volume reduction, Recovery and reuse.
  • 29.  Separate e-waste from organic waste in your home
  • 30.  Dont give used dry cell batteries, mobile phones, printer cords, fluorescent lamps and other such household objects to unorganized scrap dealers
  • 31.  Buy rechargeable batteries for power tools, home appliances and digital cameras
  • 32. If treated properly, electronic waste is a valuable source for secondary raw materials.
  • 33. As long as consumers discard electronic waste, this is one sector that will not face the heat of the economic slowdown, believe experts.
  • 34. ENVIRONMENTALLY SAFE The cutting edge of recycling technology is used to keep waste by- products to an absolute minimum. By using advanced Computer waste techniques we can can be collected on extract greater regular basis quantities of base depending on products of reduced quantities which can cost. either be deposited or recycled again.ECONOMICAL CONVENIENT
  • 35. THE “E-DAY”Nearly 300 tones of old computerequipment and mobile phones werecollected free-of-charge during NewZealands first national e-Day inSeptember 2007.
