3. E-waste ?
It may be defined as, computers, office electronic
equipment, entertainment devices & many other
electronic or electrical devices which are
unwanted, broken & discarded by their original
users are known as ‘E-Waste’ or ‘Electronic Waste’
E-waste
5. Categories of E-Waste
Large household appliances
Small household appliances
IT & Telecommunication equipment
Consumer equipment
Lighting equipment
Electrical and electronic tools
Toys and sport equipment
Medical devices
Monitoring and control instruments
automatic dispensers
7. How these become E-Waste?
Reasons:-
Advancement in technology
Changes in Style, Fashion & Status
Nearing the end of their useful life
Not taking precautions while handling them
8. Composition of E-waste
Electronic appliances are composed of hundreds
of different materials that can be both toxic and
equally of high value. While majority materials
such as iron, aluminium, plastics and glass
account for over 80 % weight of e-waste,
whereas valuable and toxic materials are found in
smaller quantities but are still of high importance.
9. Hazards associated with E-waste
There are many harmful materials used in consumer
electronics include :
Lead
Mercury
Cadmium
Hexavalent chromium
Plastic including PVC etc.
11. E-waste scenario in India
India generates about 4.1 million tonnes of
e-waste currently and it is expected to reach
8 million tonnes by 2025. In India e-waste is
growing at the rate of 10% per annum and it
constitutes 3- 8% of municipal solid waste.
13. E-Waste Disposal
Methods of treatment & disposal
Landfilling
Incineration
Pyrolysis
Existing E-Waste Management Practices in India
Plastic Waste
Products made from plastics such as keyboards, casing, front or real panel.
Miscellaneous parts encased in plastics Management Practice - The shredding & melting
14. Printed Circuit Board Waste
Used in electronic parts such as motherboard, TV internal circuits, etc.
Management Practice – De soldering & open burning to remove metals.
Miscellaneous Waste
Chips, electronic wires, broken glass waste, copper containing waste.
Management Practice- Chemical stripping & open burning & some of the waste is mixed with the
municipal solid waste
Liquid Waste
It contains internal chemicals, general waste, acid stripping waste. Management Practice
-Sewerage system
15. Recycling of E-Waste
Disassembly/dismantling
Disassembly is the systematic removal of components, parts, a group of parts or a
subassembly from a product which is in E-Waste.
Upgrading
It includes comminuting and separation of materials using mechanical / physical and/or
metallurgical processing. Methods to recover materials include incineration and refining.
Materials Recovery
The material are recovered by recycling facilities. The plastic, glass, metals can be
recovered by sorting them before mixing with other waste.
17. While the world is marvelling at the
technological revolution, countries like India
are facing an imminent danger.
E-waste of developed countries, such as the
US, dispose their wastes to India and other
Asian countries.
Major reasons for exports are cheap labour.
Recycling a computer costs USA and Europe
20 US dollars whereas India only 2 US dollars.
Indian Scenario
18. Advantages of Recycling E-Waste
• Asset recovery
• Reduction of need for landfills
• Reduction of junks and clutters
• Resale and Reuse
• Creation of jobs
19. CONCLUSION
1. As far as e-waste is concerned, it has emerged as one of the fastest growing waste streams world
wide today.
2. Electronic equipment is one of the largest know sources of heavy metals without effective
collection, reuse, and recycling systems, they will be dangerous to environment
3. Reuse and recycling of electronic equipment is a beneficial alternative than disposal
4. Product design by using safe and environment friendly raw materials and most emerging
technologies
