WHAT IS E-WASTE?
Electronic waste or e-waste is any broken or unwanted electrical or electronic appliance after their useful service life.
It is a point of concern considering that many components of such equipments are considered toxic and are not bio-degradable
SOURCES OF E-WASTE
 IT and Telecom equipments
 Large household appliances
 Toys , leisure and sports equipments
 Medical devices
 Electrical and Electronic equipments
 Monitoring Devices
IS IT A HAZARDOUS WASTE?
E-Waste contains several different substances and chemicals, many of which are toxic (Pb,Cd,Hg,Be) and are likely to create adverse effect on environment and health.
EXAMPLE
When brominated flame retardant plastic or cadmium containing plastics are landfilled, both polybrominated dlphenyl ethers (PBDE) and cadmium may leach into the soil and groundwater. It has been found that significant amounts of lead ion are dissolved from broken lead containing glass, such as the cone glass of cathode ray tubes, gets mixed with acid waters and are a common occurrence in landfills.
DO YOU KNOW……..
E-Toxic components in computers contains heavy metals like Pb and Cd and pvc coated copper cables and palstics computer casings that releases highly toxic dioxns and furans…
Cellular phones contains lead cadmium mercury and arsenic . It has been estimated that 500 millions phones ready for disposal and still today cellphones e-waste has not be taken for diposal
EFFECT ON ENVIR0NMENT
 Pollution of ground water
 Air pollution
 Acidification of soils
 E-Waste accounts for 40 percent of thelead and 75 percent of the heavy metalsfound in landfills
RECYCLING OF E-WASTE
TREATMENT OPTION OF E-WASTE:-
 Land Filling
 Incineration
TECHNOLOGY CURRENTLY USED:-
• Decontamination
• Dismantling
• Pulverization/hammering
• Shredding
