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.

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
