Slide1 l.jpg


Electronic waste, "e-waste" or "Waste Electrical and Electronic Equipment" ("WEEE") is a waste consisting of any broken or unwanted electrical or electronic appliance.

It is a point of concern considering that many components of such equipment are considered toxic and are not biodegradable.

Slide2 l.jpg

India generates close to

500,000 tons e-waste p.a.

Expected to touch a million ton by 2011

Slide3 l.jpg


Broad break up appears as under:

Mumbai : 50,000 tons

Delhi : 35,000

Bangalore : 30,000

Chennai : 25,000

Kolkata : 19,000

Ahmedabad : 14,000

Hyderabad : 13,000

Pune : 10,000

Indore : 8,000

ready for disposal in India

What contributes to e waste l.jpg
What contributes to e-waste?

A relatively new category of waste brought along with the high-tech boom

E-waste includes all types of electronic equipments/ products which have become obsolete or have been discarded due to:

Advancement in technology

Changes in fashion, style, status or perception

Nearing the end of their useful life

Generally understood to refer to any old, obsolete, end-of-life appliances using electricity which have been disposed off by their owners

How informal sector deals with?

A relatively new industry in India, traditionally dominated by the unorganized segment

Scrap dealers and rag-pickers gather e-waste from households in their area of operation and employ crude and highly unsafe processes for recycling the same, causing significant environmental damage

open burning of wires to extract resalable copper, soaking of circuit boards in acid baths to extract precious metal, disposing the residue into open drains or land, etc.

The formal e-waste recycling segment consists of a few large players which have the proper infrastructure to handle WEEE equipment

The unorganised segment often employs crude and highly unsafe processes for while recycling e-waste, and extracting precious materials therefrom

Magnitude of e waste in india l.jpg
Magnitude of e-waste in India

As per a study released by MAIT, India generated 330,000 MT of electronic waste in 2007, while an additional 50,000 MT was illegally imported

MAIT estimates that by 2011, e-waste in India would touch 470,000 MT

The Western region contributes maximum to e-waste generation – up to 35%

Sixty five cities in India generate up to 60% of total e-waste

Ten states alone generate more than 70% of total e-waste

MAIT estimates that only 19,000 tonnes of the total e-waste generated gets ultimately processed by the formal recycling sector

As per the study, around 94% of corporates in India do not have a policy on disposal of obsolete IT products/ e-waste

Major toxic elements in e waste l.jpg
Major toxic elements in e-waste

Due to the pervading reach of information technology in trade and commerce, computer waste is the most significant of all e-waste, along with televisions and cellular phones

E-waste contains both valuable as well as harmful components

Valuable components include precious metals such as gold, silver, copper, palladium, etc.

Harmful substances include lead, mercury, cadmium, etc.

Some of the key toxic elements contained within components of a computer include:
