This document discusses green electronics and e-waste management. It begins by defining green electronics as emphasizing the elimination of harmful substances in electronics and proper disposal of electronic waste. It then discusses how e-waste is generated, the hazardous substances it contains, and common methods of e-waste disposal including incineration, landfilling, and recycling. Statistics on e-waste amounts and export locations are also mentioned. The document highlights advantages like a healthier environment from proper e-waste handling and disadvantages like pollution if not disposed of correctly. It stresses the importance of sustainable e-waste practices.

3. Objective
Green Electronics = Green + Electronics
The 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.

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

5. E-waste Generation

7. 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)

8. E-toxic components in computers
composition of personal computer
28% plastic
27% silica
20% Fe metals
18% Al metals
7% Pb,Cd,Hg metals

9. E-waste Export
ASIA
CANADA EUROPE
U.S.A. DELHI
ACCARA KARANCHI GUI YU

11. Disposal of e -waste
Basically, three techniques are used for the disposal of
E-waste materials:
1).Incineration
2).Landfillng
3).Recycling

12. 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 .

14. Land filling
Simplest & 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.

15. Methan Leachate treatement system

16. 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).

17. STATISTICS

18. Advantages
Ecofriendly techniques
Healthy environment
Reduce, Reuse & Recycle
Electricity & heat generation

19. Disadvantages
Air pollution
Water pollution
Soil pollution
Health problems

20. Essence
Never waste E-waste
Apply Green- Electronics
& Save the Planet.
