    Electronic Waste

    e-waste:-by-product of a technologicalrevolution

    According to the EPA, an estimated 5to 7 million tons of computers, televisions,stereos, cell phones, electronic appliancesand toys, and other electronic gadgetsbecome obsolete every year.

    Computer monitors and older televisionpicture tubes:-

    four pounds of lead

    Problem if not recycled or dumped.

    Electronic Waste:Whats The Big Issue?

    According to the U.S. Environmental Protection Agency, by 2004,as many as 315 million obsolete computers 1.5 million computerscurrently enter the waste stream each could be disposed of in

    landfills

    Hazardous elements lead, mercury and cadmium found inelectronics can be dangerous when they are compacted at landfills.

    Largest source of cadmium in municipal waste:

    rechargeable nickel-cadmium (NiCd) batteries, commonly found inlaptops, cell phones and cameras.

    These toxics pose a threat to human health when handledimproperly.

    E-Waste Predictions

    FACTS AND FIGURES ABOUT E-WASTE

    Toxics link, a Delhi based organization

    says that India generate $1.5 billion worth ofe- waste annually.

    40 million computers were obsolete in2001

    Only about 10% were recycled

    Importance Of

    Computer RecyclingThe electronic computerequipment is a complicatedassembly of more than 1000

    materials, many of which are highlytoxic

    The e-toxic components incomputers include:

    Computer circuit boards containingheavy metals like lead and cadmium

    Computer batteries containingcadmium

    ConclusionCompanies go after newer products without actually lookingafter the impacts they have on the environment.

    Green electronics deals with creating awareness about theelectronic wastes that are being introduced very rapidly.

    It focuses on disposal, recycling, designing products that areless hazardous and more environment friendly.

    When your device becomes obsolete return it tothe manufacturers for them to ensure a sound

    waste management
