What is E-waste? – What causes E-waste?: Rapid development of upgraded electronic equipments forces the disposal of outdated equipments. – What makes E-waste hazardous?: All electronic equipments are made up of materials, which are harmful to human and pollute the environment when exposed. The harmful materials used in the manufacture of electronic equipments are Lead, Mercury, Plastics, CFCs, Cadmium, etc. – Current status of E-waste: E-waste now a day’s forces the world experts to turn back, as it’s a rapid growing problem in the developed and developing countries to recycle it or to dispose it safely so that they don’t pose any environmental pollution or hazards. – What caused the current state of E-waste: The lack of awareness about the hazardous & polluting nature of E-waste. And the cost to recycle E-wastes. – How to control E-waste? Reduce and Recycle: When a equipment is not working it doesn’t mean that the whole equipment has spoiled but generally just one part. By trying to use the equipments as long as possible by getting it repaired at service centers helps in reducing the accumulation of E-wastes. On the other hand certain equipments have to be disposed, at that time recycling of them prevents E-waste. – How to recycle?: The recycling of E-waste is not a simple process that can be performed all were, as they deal with harmful materials, and which requires lot of stuffs. The recycle of E-waste is done in many categories according to the material out of which it is made. – Benefits of recycling E-waste: The electronic equipments are made of material or resources such as Lead, Mercury, Plastics, CFCs, Cadmium, etc., which are nonrenewable can be recovered by the recycling process. Thus preventing nonrenewable resources from becoming extinct. Due to the availability of resources by recycling too they may account for the decrease in cost of the equipments. – Why recycling of E-waste is costly: The recycling of E-waste is costly when compared to recycling of other matters. This is because the composition of the equipments are harmful the recycling of which should be done with extensive care in hi-tech manner with expensive tools. The recycling of E-waste requires large labor as the primary aspect of recycling them is to categories them in metals, plastic, glass, etc., for further processing. As major constituent of E-waste is circuit board the de-soldering of which requires labor? These things makes recycling of E-waste costly. – Steps to control E-waste: The major reason of E-waste is the lack of awareness about it among the consumers of the electronic equipments. The control of E-waste can be achieved by creating awareness to the consumers about the hazardous nature of the equipments on disposal while selling the products. The E-waste recycle centers should be in reach of the consumers to disclose them safely to the recycler. The produce of the electronic equipments can implement the E-waste recycle unit

2. What’s e-waste?
E-waste are the outdated electronics
or the electronics that have reached the
end of their effective lifespan or broken
in someway. Common e-waste of present
include cell phones, computers, DVD
players, televisions, and many other
gadgets and electronics.

3. E-wastes

4. Types of e-waste
Based on reason of disposal
Disposal due to new technology
Disposal due to break down
Based on Electrical article
Computer
Telephone
Television

5. What causes e-waste?
The rapid development of science and
technology have upgraded all electronic
which forces the disposal of outdated
equipments which are e-waste.
Human mentality too account for e-waste
which tend to buy new products for existing
ones.
As for other problems of pollution,
Population also account for e-waste.

6. Why e-waste is harmful?
E-waste is not bio-degradable.
E-waste are harmful because the electronics
are made up of hazardous materials like
lead, mercury, arsenic,cadmium, etc.,
which makes them harmful or hazardous
when exposed or burnt.
Lead and Cadmium that accumulates in the
environment has highly acute and chronic
toxic effects on all forms of life.

7. Mercury
transforms into
methylmercury in
water, where it can
accumulate in living
organisms, typically
via fish,
concentrating in
large fish and
humans at the top
of the food chain.

8. Current status of e-waste
E-Waste is responsible for 70% of the toxic
waste in landfills.
 It is estimated that there are over a billion
obsolete personal computers in the world.
Not only the developed countries, but also
the developing countries face this problem.
 This forces the world experts to turn back,
to recycle e-waste or to dispose it safely so
that they don’t pose any environmental
pollution or hazards.

9. Statistics of e-waste

10. Cause of this state
The lack of awareness about the e-waste.
Out of reach of e-waste recycle units.
The cost or high investment required for
recycling of e-waste.
The labours required for recycling and the
hazardous materials contained.

11. How to control e-waste?
Reduce by Reuse and Recycle
The best way to control e-waste is to reuse
the electronics that hasn’t meet its
effective life span, by secondhand use,
repair and use.
On the other hand it is certain to dispose
some electronic, in such case recycling
should be employed.

12. Recycling of e-waste
Recycling of e-waste is
not simple as in other
cases.
It requires high
techniques, equipments
and method.
It should be done with
many safety measures.

13.  It involves human resource than the
machines.
 It is done in many ways according to the
material which is to be recycled.
Common ways of e-waste recycling are
Incineration, Landfills and Scrap yards.

14. E-waste recycle statistics

15. Benefits of recycling e-waste
Electronics which are made of non
renewable resources like Lead, Copper,
Cadmium, Mercury, etc., by recycling can be
recovered.
Reduces the cost of the electronics due to
recovery of rare resources.
Provides job opportunity for many.

16. For instancen the
recycling of a computer
gives.
• Metal: 100%
Recyclable
• Glass: 99% Recyclable
• Plastic: 100%
Recyclable
Recycling of old lamps
provide glass which can
be easily recovered.

17. Why recycling of E-waste
is costly:
The composition of the electronics are
harmful the recycling of which should be
done with extensive care in hi-tech manner
with expensive tools.
The primary aspect of recycling them is to
categories them in metals, plastic, glass,
etc., for further processing.
The major constituent of E-waste is circuit
board the de-soldering of which requires
labour.

18. E-waste recycle plant

19. Steps to control &
recycle e-waste:
Create awareness about the harmful nature
of the electronics when disposed by sellers.
The e-waste recycle centers should be in
reach of the consumers to disclose them
safely to the recycler.
The producer of the electronics can
implement the e-waste recycle unit in their
factory so as to make it simpler that the
people can reach them easily.

20. The producers should employ service centers
so as the broken ones can be repaired and
reused.
The bins for the e-wastes are to be kept at
the shops of electronics, so people can know
better about recycling options.
The e-waste management should be
included as a part of the corporation of
every city.

21. Since e-waste recycling cannot be done free
of cost tax should be collected for it.
At least one e-waste recycle unit should be
present in a district.
There by providing a new filed of job
opportunity to emerging engineers.
Research and development for the
management and handling of e-wastes
should be implemented to find better
efficient recycling methods.
