2. What is e-waste?
Electronic waste, popularly
known as „e-waste‟ can be
defined as electronic
equipments /products
connected with power plug,
batteries which have
become obsolete due to:
advancement in technology
changes in fashion, style
and status, nearing the end
of their useful life.

3. Classification
E-waste encompasses ever
growing range of obsolete
electronic devices such as
computers, servers, main
frames, monitors, TVs &
display devices,
telecommunication devices
such as cellular phones &
pagers, calculators, audio and
video devices, printers,
scanners, copiers and fax
machines besides refrigerators,
air conditioners, washing
machines, and microwave
ovens.

4. e-waste also covers recording
devices such as DVDs, CDs,
floppies, tapes, printing
cartridges, military electronic
waste, automobile catalytic
converters, electronic
components such as chips,
processors, mother boards,
printed circuit boards,
industrial electronics such as
sensors, alarms, sirens,
security devices, automobile
electronic devices

5. WHY IS E-WASTE
GROWING ?
Industrial revolution followed
by the advances in information
technology during the last
century has radically changed
people's lifestyle. Although this
development has helped the
human race, mismanagement
has led to new problems of
contamination and pollution.
The technical prowess acquired
during the last century has
posed a new challenge in the
management of wastes.

6. VOLUME OF E-WASTE
An estimated 50 million tons of
E-waste are produced each
year[The tUSA discards 30
million computers each year and
100 million phones are disposed
of in Europe each year. The
Environmental Protection
Agency estimates that only 15-
20% of e-waste is recycled, the
rest of these electronics go
directly into landfills and
incinerators. “According to a
report by UNEP titled,
"Recycling - from E-Waste to
Resources,"

7. e-Waste in India
Currently, an estimated 380,000 tonnes of
e-waste is generated annually in India,
of which 19,000 tonnes are recycled,”
said MAIT Executive Director Vinnie
Mehta. India faces a mounting challenge
to dispose of an estimated 420,000 tonnes
of electronic waste a year that it generates
domestically and imports from abroad, a
green lobby group said on October 28,
2009. Pollution control officials, who
declined to give figures for the quantity of
e-waste, said India had only six regular
recycling units with an annual capacity of
27,000 tonnes.
India..

8. "Computers and electronic equipments
which have completed their life cycle
and are obsolete in the West have started
arriving in India and the entire South
Asian market in huge quantities," says
Ravi Agarwal director of Toxics Link, a
not-for-profit environmental group.
These "cheap" machines are almost
totally made out of phased-out parts like
Intel central processing units, memory
chips, hard disk drives, and others,
extracted from cheap and obsolete
personal computers and electronic
equipment that are no longer in use on
the other side of the Pacific and the
Atlantic are being dumped in India.

9. the amount of e-waste being
produced - including mobile phones
and computers - could rise by as
much as 500 percent over the next
decade in some countries, such as
India. The United States is the world
leader in producing electronic waste,
tossing away about 3 million tons
each year. China already produces
about 2.3 million tons (2010
estimate) domestically, second only
to the United States. And, despite
having banned e-waste imports,
China remains a major e-waste
dumping ground for developed
countries.[

10. EFFECTS ON ENVIRONMENT
AND HUMAN HEALTH
Disposal of e-wastes is a particular
problem faced in many regions
across the globe. Computer wastes
that are landfilled eventually pollute
the groundwater. Acids and sludge
obtained from melting computer
chips, if disposed on the ground
causes acidification of soil. For
example, Guiyu, Hong Kong a
thriving area of illegal e-waste
recycling is facing acute water
shortages due to the contamination
of water resources.

leads.
Aluminium: nearly all
electronic goods using more
than a few watts of
power electrolytic
capacitors.
Iron: steel chassis, cases,

Nickel: nickel-cadmium
batteries.
Lithium: lithium-ion
batteries.
Zinc: plating for steel parts.
Gold: connector plating,
primarily in computer
equipment.

17. PROCESSING TECHNIQUE
In developed countries,
electronic waste processing
usually first involves dismantling
the equipment into various parts
(metal frames, power supplies,
circuit boards, plastics), often by
hand, but increasingly by
automated shredding equipment.
Magnets, eddy currents, and
trommel screens are employed to
separate glass, plastic,
and ferrous and nonferrous
metals, which can then be further
separated at a smelter.

18. Leaded glass from CRTs is reused
in car batteries, ammunition, and
lead wheel weights or sold to
foundries as a fluxing agent in
processing raw lead ore. Copper,
gold, palladium, silver and tin are
valuable metals sold
to smelters for recycling.
Hazardous smoke and gases are
captured, contained and treated
An ideal electronic waste
recycling plant combines
dismantling for component
recovery with increased cost-
effective processing of bulk
electronic waste.

21. BASEL CONVENTION
The fundamental aims of the Basel Convention are the
control and reduction of transboundary movements of
hazardous and other wastes including the prevention and
minimization of their generation, the environmentally
sound management of such wastes and the active
promotion of the transfer and use of technologies.
The Draft requires action at all levels of society:
training, information, communication, methodological
tools, capacity building with financial support, transfer of
know-how, knowledge and sound, proven cleaner
technologies and processes to assist in the concrete
implementation of the Basel Declaration.

22. Inventory management
Proper control over the materials
used in the manufacturing process
is an important way to reduce
waste generation (Freeman, 1989).
By reducing both the quantity of
hazardous materials used in the
process and the amount of excess
raw materials in stock, the quantity
of waste generated can be reduced.
This can be done in two ways i.e.
establishing material-purchase
review and control procedures and
inventory tracking system.

23. Developing review
procedures for all material
purchased is the first step in
establishing an inventory
management program.
Procedures should require
that all materials be
approved prior to purchase.
In the approval process all
production materials are
evaluated to examine if they
contain hazardous
constituents and whether
alternative non-hazardous
materials are available.

24. Another inventory
management procedure for
waste reduction is to ensure
that only the needed
quantity of a material is
ordered. This will require
the establishment of a strict
inventory tracking system.
Purchase procedures must
be implemented which
ensure that materials are
ordered only on an as-
needed basis and that only
the amount needed for a
specific period of time is
ordered.

25. Production-process Modification
Changes can be made in the production process, which
will reduce waste generation. This reduction can be
accomplished by changing the materials used to make the
product or by the more efficient use of input materials in
the production process or both. Potential waste
minimization techniques can be broken down into three
categories:
i) Improved operating and maintenance
procedures,
ii) Material change and
iii)Process-equipment modification.
Improvements in the operation and maintenance of process
equipment can result in significant waste reduction.

26. Volume Reduction
Volume reduction includes those
techniques that remove the
hazardous portion of a waste from a
non-hazardous portion. These
techniques are usually to reduce the
volume, and thus the cost of
disposing of a waste material. The
techniques that can be used to
reduce waste-stream volume can be
divided into 2 general categories:
source segregation and waste
stream concentration.
Segregation of wastes is in many Semi-automatic line for cutting
cases a simple and economical (hot wire) of CRT and removal
technique for waste reduction. of coatings

27. Wastes containing different
types of metals can be treated
separately so that the metal value
in the sludge can be recovered.
Concentration of a waste stream
may increase the likelihood that
the material can be recycled or
reused. Methods include gravity
and vacuum filtration, ultra
filtration, reverse osmosis, freeze
vaporization etc.
For example, an electronic
component manufacturer can use
compaction equipments to
reduce volume of waste cathode
ray-tube.

28. Recovery And Reuse:
This technique could eliminate waste disposal costs,
reduce raw material costs and provide income from a
salable waste. Waste can be recovered on-site, or at an off-
site recovery facility, or through inter industry exchange. A
number of physical and chemical techniques are available to
reclaim a waste material such as reverse osmosis,
electrolysis, condensation, electrolytic recovery, filtration,
centrifugation etc. For example, a printed-circuit board
manufacturer can use electrolytic recovery to reclaim
metals from copper and tin-lead plating bath.
However recycling of hazardous products has little
environmental benefit if it simply moves the hazards into
secondary products that eventually have to be disposed of.
Unless the goal is to redesign the product to use
non-hazardous materials, such recycling is a false solution.

29. Sustainable product design
Minimization of hazardous wastes should be at product design
stage itself keeping in mind the following factors*
Rethink the product design : Efforts should be made to
design a product with fewer amounts of hazardous materials.
Use of renewable materials and energy: Bio-based plastics
Bio-based toners, glues and inks are used more frequently.
Solar computers also exist but they are currently very
expensive.
Use of non-renewable materials that are safer: Because
many of the materials used are non-renewable, designers could
ensure the product is built for re-use, repair and/or
upgradeability.

30. THE INDIAN SCENARIO
While the world is marveling 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. A
recent investigation revealed
that much of the electronics
turned over for recycling in the
United States ends up in Asia,
where they are either disposed
of or recycled with little or no
regard for environmental or
worker health and safety.

31. Major reasons for exports are cheap labour and lack of
environmental and occupational standards in Asia and in
this way the toxic effluent of the developed nations
'would flood towards the world's poorest nations. The
magnitude of these problems is yet to be documented.
However, groups like Toxic Links India are already
working on collating data that could be a step towards
controlling this hazardous trade.
It is imperative that developing countries and India in
particular wake up to the monopoly of the developed
countries and set up appropriate management measures
to prevent the hazards and mishaps due to
mismanagement of e-wastes.

32. Responsibilities of the Government
Governments should enforce strict regulations and
heavy fines levied on industries, which do not
practice waste prevention and recovery in the
production facilities.
Polluter pays principle and extended producer
responsibility should be adopted.
Governments should encourage and support
NGOs and other organizations to involve actively in
solving the nation's e-waste problems.
Governments should explore opportunities to
partner with manufacturers and retailers to provide
recycling services.

33. Governments should set up regulatory agencies in
each district,
Governments should be responsible for providing
an adequate system of laws, controls and
administrative procedures for hazardous waste
management
Governments must encourage research into the
development and standard of hazardous waste
management, environmental monitoring and the
regulation of hazardous waste-disposal.
Governments should enforce strict regulations
against dumping e-waste in the country by outsiders.

34. Responsibility and Role of Industries
Companies can and should adopt waste
minimization techniques
. Manufacturers, distributors, and retailers should
undertake the responsibility of recycling/disposal of
their own products.
. Manufacturers of computer monitors, television
sets and other electronic devices containing
hazardous materials must be responsible for
educating consumers and the general public
regarding the potential threat to public health and
the environment posed by their products.

35. Responsibilities of the Citizen
Waste prevention is
perhaps more preferred to
any other waste
management option
including recycling.
E-wastes should never be
disposed with garbage and
other household wastes.
NGOs should adopt a
participatory approach in
management of e-wastes.

36. While buying electronic products
opt for those that:
are made with fewer toxic
constituents
use recycled content
are energy efficient
are designed for easy upgrading
or disassembly
utilize minimal packaging
offer leasing or take back options
have been certified by regulatory
authorities. Customers should
opt for upgrading their
computers or other electronic items
to the latest versions rather than
buying new equipments.

37. E-waste – A global challenge
In summary one can clearly
grasp and understand the e-
waste problem is of global
concern because of the nature
of production and disposal of
waste in a globalized world.
Although it is difficult to
quantify global e-waste
amounts, we do know that
large amounts are ending up
in places where processing
occurs at a very rudimentary
level

38. This raises concerns about
resource efficiency and also the
immediate concerns of the dangers
to humans and the environment.
There is a long and often
complicated chain of events in the
e-waste problem, beginning from
an idea that someone has for a new
product and then its production,
ending in its purchase and
eventual disposal by the end user.
By engaging with various
stakeholders and relevant scientific
wisdom within this chain of
events, we are on the way to Solve
the E-waste Problem (StEP).
