ELECTRONIC WASTE- A REAL ENVIRONMENTAL THREAT

Electronic waste, "e-waste" or "Waste Electrical and Electronic Equipment" ("WEEE") is a waste consisting of any broken or unwanted electrical or electronic appliance.

HAZARDOUS

NONHAZORDOUS

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

SOURCES OF E-WASTE CONSTITUENTS HEALTH EFFECTSSolder in printed circuit boards, glass panels and gaskets in computer monitors

Lead (Pb) •Damage to central and peripheral nervous systems, blood systems and kidney damage. •Affects brain development of children.

Chip resistors and semiconductors

Cadmium (Cd) •Toxic irreversible effects on human health. •Accumulates in kidney and liver. •Causes neural damage.

Relays and switches, printed circuit boards

Mercury (Hg) •Chronic damage to the brain. •Respiratory and skin disorders due to bioaccumulation in fishes.

Cabling and computer housing

Plastics including PVC

•Reproductive and developmental problems; •Immune system damage; •Interfere with regulatory hormones

EFFECTS ON HUMAN HEALTH

E-Waste Growth

IT and telecom are two fastest growing industries in the country.

At present, India has 15 million computers. The target being 75 million computers by 2010.

Life of a computer reduced from 7 years to 3-5 years.

Mumbai at present tops the list

Mumbai : 11, 017 tonnes

Delhi : 9,730 tonnes

Bangalore : 4,648 tonnes

Chennai : 4,132 tonnes

Kolkata : 4,025 tonnes

Ahmedabad : 3,287 tonnes

Hyderabad : 2,833 tonnes

Pune : 2,584 tonnes

WASTE PILING UP

the total e-waste in India has been estimated to be

1,46,180 tonnes per year

HEIRACHY OF E-WASTE MANAGEMENT

How to reduce e-Waste?

Energy recovery

• Energy content of waste products can be harnessed directly by:

1. Pyrolysis- are used to convert organic materials directly into a synthetic gas (syngas)

2. Gasification- converts the solid waste material into solid, liquid and gas products.

Plasma pyrolysis system designedby FCIPT.

Startech’s Plasma converter System

INTEGRATED ENVIRONMENTAL TECHNOLOGY (IET)

Transforms waste into highly stable glass-like residues, recoverable metals and hydrogen-enriched gas.

IT combines three processes:1. plasma arc using multiple

graphite electrodes2. Superheated steam3. joule (resistance) heating

using glass melter technology.

E-Waste: Start Thinking About The Future

•The amount of e-waste is likely to increase because e-waste is growing at three times the rate of other public waste.•It may be responsible for 70 percent of the heavy metals in landfills, including 40 percent of all lead.•look at e-waste not as waste, but as resource.•recycling of cathode ray tube (CRT) monitors will decrease because of the replacement of CRT monitors by liquid crystal display (LCD) monitors.

CONCLUSION

E-WASTE shouldn’t be seen as a waste but seen as resource.

Students can use unusable equipments from e-waste for their research & project studies.

• The fact is that only a very small amount of discarded computers are being recycled. The truth is that this needs to change!

Hey Man, simply because you're outdated doesn't mean

you're unwanted. I'd never discard you.

THANKING YOU ALL !!!
