3. INTRODUCTION
E-waste or WEEE are Loosely discarded, surplus, obsolete
or Broken electrical and electronic devices.
-This include used electronics which are destined for Reuse,
Resale, Salvage, Recycling or disposal.
Informal Processing of E-waste
poses a serious threat of
Health and Environmental
Pollution- esp. in developing
Countries.
4.
5. BURDEN OF E-WASTE
50 million tons/ year: EPA states that only 20% is recycled
among them and rest goes to landfills and incinerators.
USA is the world leader in producing E-waste(10 m tons),
with China behind (8 m tons).
6. Guiyu in China is the biggest E waste dump (E waste
capital of the world) : With 15,000 e waste workers.
Developed Nations ship their E waste to developing
Nations because of our poor regulations over waste
disposal.
8. 1,46,000 tonnes in 2005
8,00,000 tonnes in 2012.
In India:
The amount of E waste being produced could rise as much
As 500% over next decade in India alone.
9. Why E-Waste is Growing?
Rapid changes in Technology.
Falling Prices (Competitive Tech).
Irresponsible Company Manufacturing.
10. Lack of Proper Knowledge on its risks and disposal.
Repairs cost more than new products. ( Not Upgrading)
Planned Product Obsolescence.
13. IMPACTS OF E-WASTE
Environment
1. Contamination of Ground Water:
• One Mobile Battery pollutes 600 m3 ground water.
Cadmium Mercury
PCBs Lead
• This ultimately destroys Aquatic Ecosystem.
14. 2. Air Pollution
• Incineration of these waste releases Toxic Gases
• Toxic dioxins & Furans (Comes from burning plastic
cables and PVC materials.)
3. Soil Pollution
• Acids and sludge pollute soil
(Melting Computer
Chips)
23. Information Security
Improperly erased hard dives can be reopened exposing
sensitive information like Credit card details, Private
financial data, Online transactions etc,.
In Agbogbloshie, Ghana- criminals found multimillion dollar
agreements & USA Govt Contracts, that were later leaked.
25. POLICIES & CONVENTIONS
The globally growing E waste problem was addressed in 1980,
and the tightened environmental regulations lead to Toxic Traders.
They used to ship E waste to
developing Countries (Cheap
labour, No regard for environment
and lack of standards.)
So, a new BASEL CONVENTION came forward (Geneva) that
facilitates the implementation of the regulations.
26. BASEL CONVENTION
Control & reduction of Transboundary movements of
hazardous wastes- including prevention & minimization of
their generation and the environmentally sound
management of such wastes & active promotion of the
use of technology.
It also provides assistance &
guidelines on legal and technical
issues, gathers statistical data &
conducts training on proper
management of toxic waste.
27. EXTENDED PRODUCER RESPONSIBILTY
An European legislation that will require manufacturers
to take back their electrical products when the consumer
discards them.
28. E WASTE MINIMIZATION
1. Inventory Management:
The raw materials used in manufacturing must be optimized.
New methods to manufacture with less material should be
appreciated.
2. Volume Reduction:
By removing Hazardous portion from Non-Hazardous.
3. Recovery & Reuse:
By strictly following EPR.
29. RESPONSIBILTIES & ROLES
Responsibility of Government`
Should setup
regulatory
agencies in each
district.
Strict legislations
should be
enforced.
Encourage
research in E
waste
management.
30. Responsibility of Industries
E Waste
handlers should
be properly
qualified.
Adopt waste
Minimization
Techniques.
Undertake the
disposal of their
own products
safely.
31. Role of Citizens
Customers should opt
for upgrading rather than
Buying a new one.
Never dispose it with
garbage or other household
waste.
33. RECYCLING
“Assembling, developing, promoting or buying
Of new products which are prepared from waste products.”
Dismantling
Develop new equipments
Retrieve Valuable materials
Separating Hazardous materials
34.
35.
36. LAND FILLING
Dumping or Burial of E-Waste.
Widely Used method of disposal.
Not a Safe method/ Approved.
37. Significant impacts from landfilling could be avoided by
conditioning hazardous materials from e-waste separately and
by landfilling only those fractions which cannot be
recycled and ensure that they are in state-of-the-art
landfills that respect environmentally sound technical standards.
38. INCINERATION
“Incineration is the Process of destroying waste through
burning.”
Open Burning is more harmful than controlled Incineration
(Slow burning releases more toxic gases)
39. Burning copper along with BFRs releases Dioxins, like
PBDD & PBDFs (Highly toxic).
When PVC cables are burnt, hydrogen chloride is released
(HCl corrodes lung tissue)
In Open Burning, lack of oxygen results in CO
poisoning.
Since Controlled Incineration
could decrease volume of
Disposal, it is the next best
method of Waste management.
43. CONCLUSION
This Potential Threat of E-waste must be attended quickly,
before it escalates to an unpreventable peril.
Overcoming our limitations such as- Political, Financial
and Social factors play a major role in its prevention.
Because management of E
waste is costly, it is essential
to educate and promote
research in this matter.
