ELECTRONIC WASTE- A REAL ENVIRONMENTAL THREAT qElectronic waste, "e-waste" or "Waste Electrical and Electronic Equipment" ("WEEE") is a waste consisting of any broken or unwanted electrical or electronic

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.

Energy recovery • Energy content of waste products can be harnessed directly by: 2. Pyrolysis- are used to convert organic materials directly into a synthetic gas (syngas) 5. Gasification- converts the solid waste material into solid, liquid

Plasma pyrolysis system designed

Startech’s Plasma converter System

INTEGRATED ENVIRONMENTAL TECHNOLOGY (IET) Ø Transforms waste into highly stable glass-like residues, recoverable metals and hydrogenenriched gas. Ø IT combines three processes: 3. plasma arc using multiple graphite electrodes 4. Superheated steam 5. joule (resistance) heating using glass melter technology.

E-Waste: Start Thinking About Th •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

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Hey Man, simply because you're outdated doesn't mean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