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,
E-waste Generation
Hazardous substances in e-waste
Heavy metals(As,Ba ,Be,Cd,Cr,Pb,Li,Hg,Ni,Se,Zn)
Halogenated compounds PCB(Polychlorinated bi phenyles )
TBBA(Tetrabrominated-bis-phenol-A) PBB(Polybrominated di phenyl ethers)
CFC(Chloro flouro carbon )PVC(Poly vinyl chloride)
E-toxic components in computers
composition of personal computer
28% plastic
27% silica
20% Fe metals
18% Al metals
7% Pb,Cd,Hg metals

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.
Methan Leachate treatement system gas recovery system -------------
Well to
monitor Clay trap
Ground Trash
Water
Leachate collection Aquifiersystem
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).
