    What is e waste What is e waste Presentation Transcript

    • ELECTRONIC WASTE Electronic waste, " e-waste " or "Waste Electrical and Electronic Equipment" (" WEEE ") is a waste consisting of any broken or unwanted electrical or electronic appliance. It is a point of concern considering that many components of such equipment are considered toxic and are not biodegradable .
    • India generates close to 500,000 tons e-waste p.a. Expected to touch a million ton by 2011
    • Broad break up appears as under: Mumbai : 50,000 tons Delhi : 35,000 Bangalore : 30,000 Chennai : 25,000 Kolkata : 19,000 Ahmedabad : 14,000 Hyderabad : 13,000 Pune : 10,000 Indore : 8,000 WASTE PILING UP
      • IT & Telecom Equipments
      • Large Household Appliances
      • Small Household Appliances
      • Consumer & Lighting Equipments
      • Electrical & Electronic Tools
      • Toys, Leisure & Sports Equipment
      • Medical Devices
      • Monitoring & Control Instruments
      SOURCES OF WEEE
    • Over 400 million current mobile users expected to increase to 500 million by 2010 end
    • At present, India has about 40 million computers which are expected to grow to 80 million computers by end 2010
    • Over 14 million old PCs ready for disposal in India
    • What contributes to e-waste?
      • A relatively new category of waste brought along with the high-tech boom
      • E-waste includes all types of electronic equipments/ products which have become obsolete or have been discarded due to:
        • Advancement in technology
        • Changes in fashion, style, status or perception
        • Nearing the end of their useful life
      • Generally understood to refer to any old, obsolete, end-of-life appliances using electricity which have been disposed off by their owners
    • How informal sector deals with?
      • A relatively new industry in India, traditionally dominated by the unorganized segment
      • Scrap dealers and rag-pickers gather e-waste from households in their area of operation and employ crude and highly unsafe processes for recycling the same, causing significant environmental damage
        • open burning of wires to extract resalable copper, soaking of circuit boards in acid baths to extract precious metal, disposing the residue into open drains or land, etc.
      • The formal e-waste recycling segment consists of a few large players which have the proper infrastructure to handle WEEE equipment
    • Unsafe methods for e-waste recycling
      • The unorganised segment often employs crude and highly unsafe processes for while recycling e-waste, and extracting precious materials therefrom
    • Magnitude of e-waste in India
      • As per a study released by MAIT, India generated 330,000 MT of electronic waste in 2007, while an additional 50,000 MT was illegally imported
      • MAIT estimates that by 2011, e-waste in India would touch 470,000 MT
      • The Western region contributes maximum to e-waste generation – up to 35%
      • Sixty five cities in India generate up to 60% of total e-waste
      • Ten states alone generate more than 70% of total e-waste
      • MAIT estimates that only 19,000 tonnes of the total e-waste generated gets ultimately processed by the formal recycling sector
      • As per the study, around 94% of corporates in India do not have a policy on disposal of obsolete IT products/ e-waste
    • Major toxic elements in e-waste
      • Due to the pervading reach of information technology in trade and commerce, computer waste is the most significant of all e-waste, along with televisions and cellular phones
      • E-waste contains both valuable as well as harmful components
        • Valuable components include precious metals such as gold, silver, copper, palladium, etc.
        • Harmful substances include lead, mercury, cadmium, etc.
      • Some of the key toxic elements contained within components of a computer include:
