• 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.

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

24

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.

Recycling and Reprocessing Units in

India.

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.
