INTRODUCTION
Over 2 million old PCsReady for Disposal in India
Over 75 million current mobile users
expected to increase to200 million by 2008 end.
At present, India has about
16 million computerswhich are expected to grow
to 75 million computersby 2010
• 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
SOURCES OF E-WASTE.
• IT & Telecom Equipments
• Large Household Appliances
• Small Household Appliances
• Consumer & Lighting Equipments
• Electrical & Electronic Tools
• Toys, Leisure & Sports Equipment
• Medical Devices
• Monitoring & Control Instruments
IS E-WASTE HAZARDOUS ?
E-Waste contains several different substances and
chemicals, many of which are toxic and are likely to
create adverse impact on environment and health, if
not handled properly. However, classification of E-
waste as hazardous or otherwise shall depend upon
the extent of presence of hazardous constituents in
it.
Effects On Environment.
Pollution of Ground-Water.
Acidification of soil.
Air Pollution.
E-Waste accounts for 40 percent of the
lead and 75 percent of the heavy metals
found in landfills.
Effects On Human Health Damage to central and peripheral nervous systems,
blood systems and kidney damage. Affects brain development of children. Chronic damage to the brain. Respiratory and skin disorders due to bioaccumulation in
fishes. Asthmatic bronchitis. DNA damage. Reproductive and developmental problems. Immune system damage. Lung Cancer. Damage to heart, liver and spleen.
E-Waste Management In industries management of e-waste should begin at the point of generation. This can be done by waste minimization techniques and by sustainable product design. Waste minimization in industries involves adopting:
1.Inventory management,
2.Production-process modification,
3.Volume reduction,
4.Recovery and reuse.
The Current Scenario in India.
• E-WASTE PILING UP Mumbai at present tops the list• Mumbai - 11, 017 tons• Delhi - 9,730 tons• Bangalore - 4,648 tons• Chennai - 4,132 tons• Kolkata - 4,025 tons• Ahemdabad -3,287 tons• Hyderabad- 2,833 tons• Pune - 2,584 tons• Surat - 1,836 tons
E-WASTE Growth in India
The Total E-Waste in India has been Estimated to be
1,46,180 Tonnes per year.
Recycling Of 1. Treatment Options Of E-Waste.
• Land filling.• Incineration.
2. Technologies In India.• E-waste trade value chain.• Environmentally Sound E-waste Treatment Technology.• CRT treatment technology.
3. Technology Currently Used in India.• Decontamination. • Dismantling.• Pulverization/ Hammering.• Shredding.• Density separation using water.
Approach and Methodology.
•Step 1: Identify the E-waste category item.•Step 2: Identify the E-waste composition or determine it.•Step 3: Identify possible hazardous content in E-waste.•Step 4: Identify, whether the E-waste component is hazardous or the entire E-waste item is hazardous.

• The Ministry of Environment and Forests in India is currently drafting “WEEE" legislation.
• The new legislation to hold e-waste producers accountable for their action.
• E-waste/ components, which are hazardous in nature need to be covered under the purview of – The Hazardous Waste (Management and handling) Rules 2003– The Batteries (Management and Handling) Rules, 2001– The Ozone Depleting Substances (Regulation and Control) Rules,
2000.
• Greenpeace International is pushing for more stricter legislation.
