What is Electronic Waste ?
• e-Waste is waste of electronics / electrical goods that have
reached their end of life
• Such electronics goods may be television, telephones,
radios, computers, printers, fax machines, DVDs and CDs
etc.
Different types of e-waste?
7
Telecommunication Waste:
•Mobile phones
•Telephones
•Telephone exchanges Wireless Equipment cables and related scrap material
•PC and TV
Electrical Waste:
•Switches
•Relays
•Connectors and related Scrap Material.
Electronic Waste:
•Electronic – metal waste
•Printed Circuit Boards
•E – Equipment and Machinery
•IC
•Sockets Connectors.
Cable Waste:
•PVC
•Pre Insulated Copper and Aluminium Cable waste.

How the city falls prey to e-Waste?
• Chennai generates close to 10 tones of electric waste per
day.
• A study in 2009 revealed that from faulty computers and
hardware, Chennai generates over 14000 tonnes of e-
waste.
• For the fiscal 2008-2009 the waste generated through
compact disc and tapes is estimated to be around 2800
tonnes , while mobile phones generated a solid waste of 47
tonnes during the period in Chennai.
• The hazardous waste management rules
were formulated in 2003 but still the
electronic waste and hazardous material
are not treated scientifically in Chennai
and are dumped along with solid waste
How this become e-Waste?
• Changes and Advancement in Technology
• Changes in Fashion , Style & Status
• Changing in configuration
• Attractive offers from manufacturers
• Small life of equipment
Generators of e-Waste?
• Small business and house-hold.
• Large Businesses.
• Institutions and Government offices.
• Equipment manufacturers.
• IT companies
• Toys, Leisure & Sports Equipment
• Medical Devices
• Monitoring & Control Instruments
e-Waste in INDIA
• Over 2million E-Waste is generated ever year .
• Harmful techniques like burning wires are common
practice in the informal recycling sectors in
big cities in India.
2 million ton is contributed by India
40 Million ton E-waste produced globally
• Chennai ranks third among the top 10 cities in the country
• 95% of the e-waste is segregated, dismantling and
recycled in urban slum.
• Formal sector that is into recycling does not incinerate or
use an chemicals; it uses environmental sound processes
• In Chennai still ignorant about e-waste
hazardous and they just dump them in
open space and garbage.
• According to Mr.Vinnie Mehta executive director of
Manufacturers Association of Information Technology
(MAIT), “ AN ESSTIMATED 3.30 LAKHS METRIC TONNES
OF e-WASTE GENERATED IN INDIA”
• only about 40 percent of the e-waste gets into the recycling
stream while the rest remains in warehouse because of an
inefficient collection system
• At 2011 India has touched 4.70 lakhs tonnes
of e-waste
Why e-Waste is a problem?
• Composed of Hazardous Materials.
• Electronic products are difficult to Recycle.
• Products are quickly obsolete and discarded.
• Discarded Electronics are managed badly.
• Most E-Waste goes to landfills.
• Most recyclers don’t recycle, they export.
• Electronics products like computers and cell phones
contain a lot of different toxins.
• For example, Cathode Ray Tubes (CRTs) contain heavy
metals such as Lead, Barium and Cadmium, which can
damage human nervous and respiratory system if they
enter the water system.
workers manually dismantle most
electronic equipment and sort out
valuable commodities that are
sold to various recyclers.
CRTs ready to be
"crushed" for recycling.

Effects of e-Waste
On Environment
• Pollution of Ground-Water.
• Acidification of soil.
• Air Pollution.
• E-Waste accounts for 40 percent of the lead and 75
percent of the heavy metals found in landfills.
On Human Health
• DNA damage.
• Lung Cancer.
• Damage to heart, liver and spleen.
• Chronic damage to the brain.
• Asthmatic bronchitis.
Issues and Challenges.
Issue and Challenges
Leaching of heavy metals
from Landfills and
Incinerators
Exposure to workers &
communities
Unawareness (brand new
items are also kept in waste)
Less reuse
Collection system
Legal framework
• Accurate figures not available for rapidly increasing e-
waste volumes generated domestically and by imports.
• Low level of awareness among manufacturers and
consumers of the hazards of incorrect e-waste disposal.
• Major portion of e-waste is processed by the
informal (unorganized) sector using
rudimentary techniques.
Way of Treating e-Waste.
1. Treatment Options of E-Waste
• Land filling.
• Incineration.
• Reuse
• Recycle
2. Technology Currently Used in India
• Decontamination.
• Dismantling.
• Pulverization/ Hammering.
• Shredding.
• Density separation using water.
• Increase life span of
product
Landfills
• Leaching problem (70% of
Heavy metals in landfills
are because of E-waste)
• Fumes of Heavy metals
released in atmosphere
• Municipal incinerators are
giving dioxins

Probable Solution.
Need for stringent health standards and environmental protection laws in India,
Extended producer responsibility,
Import of waste under license,
Producer-public-government cooperation,
Awareness program, following safer and efficient methods
Choosing safer technology and cleaner substitute,
Monitoring of compliance rules,
Reduction of waste at source,
Investment opportunity in waste management sector
Recognition to the unorganised sector in India.
Don’t discard but donate
Responsibility and Role
Citizens
• E-wastes should never be disposed with garbage and other
household wastes.
• Customers should opt for upgrading their electronic items
to the latest versions rather than buying new.
• While buying electronic products consumers should opt for
those that:
• are made with fewer toxic constituents.
• use recycled content.
• are energy efficient.
Responsibility and Role
Industries
• Manufacturers, distributors, and retailers should
undertake the responsibility of recycling/disposal of their
own products.
• Manufacturers must be responsible for educating
consumers regarding the potential threat posed by their
products.
• Companies should adopt Waste Minimizing
Techniques.

How to Disposal of e-Waste?
Donate working older equipment to schools colleges or government entities in need.
If PC are out of order then return it to the manufacturers. (HCL and Wipro in India has best take back service)
Send waste goods to authorised recycling facility for proper disposal.
