Electronic waste has become a major threat to environment. This presentation shows you about the recycling process.

1. RECYCLING OF
E-WASTE

2. E-waste
The E-waste refers to the electrical and
electronic devices after its usage or its
expiry
Laptops Cellphones
Television setsComputers

3. Reuse of
electronic devices
A slight modification of electronics
devices can be made and it can be reused
or sold as second-hand product to
anyone.

4. Process involved in E-Waste recycling
Storage
:
collection Transportation

5. Dismantling
Hand picking of E-waste
Shredder

6. Ferrous material= Steel and Iron metal
Non ferrous material=aluminum and copper

7. The plastic and glass waste are
separated by the Density variation process

8. DISPOSAL METHODS

9. • Temperature=
900-1000 “C
Incineration plant
Advantages
:Minimum land
:operates in any wreathe
:Stable odorless residue
:50% initial value reduction
Disadvantage
:expensive to build
:needs high energy
:requires skilled personnel and continuous
maintenance

10. • The electronic circuit is soaked in the powerful sulfuric or nitric acid
• Due to the acid the dissolution of metals in electronic circuit takes place
• The metals recovered is used for the manufacturing of products
• The hazardous acid is discarded safely
• And the metals recovered are gold, silver, lead and copper
Acid Bath

11. • Clay and plastic is used for the leachate resin
• It is termed as toxic time bomb as it affects both soil and ground water
• Not a environmental sound process for waste disposal
Land fill

12. E-Waste recycling
Advantage
• Recovery of valuable material
• Yielding of valuable material acquires
economic value
Disadvantage
• Improper disposal cause health
hazard
• Chemicals present in e-waste are very
harmful
• Landfill causes pollution to both land
and water
