E-waste refers to outdated or broken electronics, contributing significantly to global toxic waste due to hazardous materials like lead and mercury. The increase in e-waste is driven by rapid technological advancements and consumer behavior, with both developed and developing countries facing disposal challenges. Effective management includes recycling, raising awareness, and improving accessibility to recycling facilities, but it requires specialized methods and considerable investment.

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E-waste are the outdated electronics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which forces the disposal of outdated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.

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.
