3. •Electronic waste, ”e-waste” or ”Waste
Electrical and Electronic Equpiment” is a
waste consisiting of any broken or
unwanted electrical or electronic
appliance.
•E-waste materials may be valuable and
recyclable, such as random access memory
and reusable laptops. However, hazardous
materials, such as cathode ray tube
monitors, require special handling in
disposal.
•Electronic Waste (e-waste) is one of the
fastest growing segments of our nation’s
waste stream.
What is e-waste?
4. Current Scenario in India
Among Indian states, Maharashtra generates the most e-waste (19% or 3.96 lakh
tonnes).
Mumbai, the business capital of the country, produces the most e-waste at 96,000
metric tonnes (MT) every year. A chunk of Mumbai’s e-waste can be attributed to
banks and corporates located in the city, that periodically dispose off their
computer and telecommunication equipment.
5. • A mere 5 per cent of India's total e-waste gets recycled due to poor
infrastructure, legislation and framework which lead to a waste of
diminishing natural resources, irreparable damage of environment
and health of the people working in industry.
Over 95% of e-waste generated is managed by the
unorganized sector and scrap dealers in this market, dismantle
the disposed products instead of recycling it.
India is expected to have 800 million mobile phone users and
460 million computer users by the year 2020.

6. E-waste : A Global
Challenge
• China lead the way, with 7.2 million tons
per annum, while the USA (6.3), Japan
(2.1), India (2.0) and Germany (1.9) trail
behind.
• The world produces as much as 50 million
tonnes of electronic and electrical waste
(e-waste) a year, weighing more than all of
the commercial airliners ever made. Only
20% of this is formally recycled.
• The e-waste produced annually is worth
over $62.5 billion, more than the GDP of
most countries. There is 100 times more
gold in a tonne of e-waste than in a tonne
of gold ore.
7. Causes
Development :
As of now, It is estimated that there are over a billion personal computers in
the world. In developed countries these have an average life span of only 2 years.
In the United States alone there are over 300 million obsolete computers.
Technology :
In this modern era technology is growing at lightning fast speed. This
technology results in the coming of newer products and appliances. The major
contributors are MNC's( Multinational corporations).
Population :
Population has triggered the above points even more. With increasing
population the amount of e waste increases because the old computers bought
would be thrown with the introduction of better technology devices.
8. Legislation
China and Japan have formulated
numerous laws for e-waste management,
forming a relative complete system.
The various legislations enacted by the
Government of India are:-
• The Hazardous Wastes (Management
andHandling) Amendment Rules,
2003;
• Guidelines for Environmentally
Sound Management of E-waste,
2008;
• The e-waste (Management and
Handling) Rules, 2011.
Till date, 25 states have passed some
type of e-waste related legislation.
State laws vary and may include
landfill or incineration bans, advanced
recycling fees (consumers pay a
recycling fee up front), and producer
responsibility or take-back programs.
9. Toxic Substances Present In E-Waste
E – waste contains several different substances and chemicals many of which are toxic and likely to
create adverse impact on environment. Classification of e – waste depends upon the extent of
presence of Hazardous constituents in it. Constituents of E – waste are:
1. Hazardous Substances – These dangerous substances cause serious pollution and put workers
at risk when the products are manufactured or thrown out. Of particular concern is the
exposure of children and pregnant women to lead and mercury. These metals are highly toxic
and can harm children and developing fetuses even at low levels of exposure.
2. Non Hazardous Substances – These substances cause less pollution and not harmful as
compared to Hazardous substances as these substances mainly consist of useful materials.
11. Any appliance that runs on electricity has the potential to cause
damage to the environment if it is not disposed of in a responsible way.
Common items of electrical and electronic waste are:
1. Large household appliances – refrigerators/freezers, washing
machines, dishwashers.
2. Small household appliances – toasters, coffee makers, irons,
hairdryers.
3. Information technology and telecommunications equipment –
computers, mobile phones, laptop, printers, scanners,
photocopiers
4. Consumer equipment – televisions, stereo equipment, electric
toothbrushes.
5. Lighting equipment – fluorescent lamps.
Types Of E-Waste
12. 6.Electrical and electronic tools – handheld drills,
saws, screwdrivers.
7. Toys, leisure and sports equipment.
8.Medical equipment systems – with the exception of
all implanted and infected products.
9. Monitoring and control instruments.
14. Environmental impact of e-waste
The unsafe disposal of e-waste is a
growing problem and the
environmental effects and human
health hazards are very serious.
Liquid and atmospheric releases
end up in bodies of water,
groundwater, soil, and air and
therefore in land and sea animals –
both domesticated and wild, in
crops eaten by both animals and
human, and in drinking water.
15. Effects on Air
•Some waste disposal facilities opt for burning
as a means of dealing with electronic waste.
•Burning the waste can release dioxins and
particulates into the air, which has serious
health problems including:
•reproductive problems
•developmental problems
•cancer
•immune system damage
• These particulates can potentially travel for
miles beyond the confines of a disposal facility
if not properly regulated.
16. Effects on Water
•When electronics containing heavy metals
such as lead, barium, mercury, lithium (found
in mobile phone and computer batteries), etc.,
are improperly disposed, these heavy metals
leach through the soil to reach groundwater
channels which eventually run to the surface
as streams or small ponds of water.
•Local communities often depend on these
bodies of water and the groundwater.
•Apart from these chemicals resulting in the
death of some of the plants and animals that
exist in the water, intake of the contaminated
water by humans and land animals results in
lead poisoning.
•Some of these heavy metals are also
carcinogenic.
17. Effects on Soil
• E-waste that ends up in a landfill
can leak a number of heavy metals,
such as lead, mercury, and lithium.
• Some of these metals remain
in the soil.
• That heavy metal pollution can
also pollute the water table in an
area. Once that happens, it’s next
to impossible to avoid widespread
contamination of crops and grazing
animals.
19. Areas affected by e-waste
One study done on the impact of hazardous e-waste in India has estimated that over
30,000 computers have become decommissioned each year in Bangalore alone. The high
disposal of computers has cultivated more than 1,000 tons of plastics, 300 tons of lead, 0.23
tons of mercury, 43 tons of nickel, and 350 tons of copper in Bangalore.
In Bangladesh, at a shipyard in Chittagong, contamination plagued the nearby soil from
chemicals that are commonly found in electronic waste. Soil samples contained compounds
such as “lead, mercury, cadmium, arsenic, antimony trioxide, polybrominated flame retardants,
selenium, chromium, and cobalt”.
In Delhi, discarded gadgets are resulting in massive piles of e-waste, which is contaminating
the soil and groundwater. The average copper concentration in top soils of e-waste sites was 30
times more than the permitted limit, whereas that of cadmium was 16 times more than the
permitted limit.
20. • Different circuits boards and computers are
burned in open fires to extract metals .
• Plastics are graded by quality and other
parts are burned to separate from metals .
Ex-
Wires are burnt to extract copper from its
outer plastic /polymer covering .
These crude recycling techniques have
resulted in widespread environmental
contamination of the surrounding water
systems,soils and air.
21. Environmental and Health
Costs
• The poor workers live and work in very bad conditions, contaminated by heavy
metals and toxic pollution.
•The groundwater in Guiyu is undrinkable.
• Eighty two percent of the kids had blood/lead levels of over 100, which is
considered unsafe by international health experts.
• A separate report by the Shantou Medical University Hospital in November 2003
found a high incidence of skin damage, headaches, vertigo, nausea, chronic gastritis,
and gastric and duodenal ulcers, especially among migrants who recycle circuit boards
and plastic.
22. Think twice before buying whether you really
need a new device and return your old
equipment to the manufacturer if possible.
