ObjectiveGreen Electronics = Green + ElectronicsThe word ‘green’ demonstrates the ‘ecofriendly’ character.
“ Green Electronics emphasizes on
elemination of harmful substances
& the disposal of electronic wastes ;
by applying ecofriendly techniques.”
Green Electronics is simply E-waste Management.

E-waste stands for Electronic wastes.
• HOW E-WASTES ARE GENERATED?
• HAZARDOUS SUBSTANCES IN E-WASTE,
• E-TOXIC COMPONENTS IN COMPUTERS ,
• E-WASTE EXPORT ON INTERNATIONAL LEVEL,

Disposal of e -waste
Basically, three techniques are used for the disposal ofE-waste materials:
1).Incineration2).Landfillng3).Recycling

incineration
Incineration involves combustion of
E-waste materials.
Volume of E-waste materials can be
Reduced upto 20-30% .
Incineration is also called as “Thermal
treatement”.
e. g. incinerators .

Land fillingSimplest & highly applicable technique .
Landfilling means “E-waste materials
are burried (filled) inside the land”.
Designing of landfills in a modern way
is a complex phenomenon.
e.g. modern landfills.

recycling
Recycling refers to the widespread collection
& reuse of E-waste.
Collection of E-waste using dedicated bins,
collection vehicals.
Recycling of complex products( computer &
electronic equipments) is slightly difficult in
comparison to single type products(PVC).
