Electronic Waste Management - Clean to Green
e-Waste
What is E-waste?
Electronic Waste (e-Waste) comprises of waste
electronic/electrical goods which are not fit for their
originally intended use. These include items such as
computers, cellular phones, stereos, refrigerators, air
conditioners, other consumer durables, etc.
Is e-Waste Hazardous?
E-waste is not hazardous waste per-se. However, the
hazardous constituents present in the e-waste
render it hazardous when such wastes are
dismantled and processed, since it is only at this
stage that they pose hazard to health and
environment.

Toxic constituents in e-waste
COMPONENTS CONSTITUENTS
Printed circuit boards Lead & cadmium
Cathode ray tubes (CRTs) Lead oxide & Cadmium
Switches & flat screen monitors Mercury
Computer batteries Cadmium
Capacitors and transformers Poly Chlorinated Bi-phenyls (PCB)
Printed circuit boards, plastic Brominated Flame Retardant casings
cable
Cable insulation/coating Poly Vinyl Chloride (PVC)

Growing EEE Industry in India
Information and telecom fastest growing industry verticals
PC sales crossed 7.3 million units in 2007-08 growing 16%;
installed base of over 25 million units
Consumer electronics market growing at 13-15% annually ; 120
million installed base of TVS
Cellular subscriber up by 96.86% over last year; Indtalled
base to cross 300 million by 2010

Recycling scenario in India
E-waste recycling is presently concentrated
in the informal (unorganized) sector
No organized collection system prevails
Operations are mostly illegal
Processes are highly polluting
Recycling operations engage in:
dismantling
sale of dismantled parts
valuable resource recovery
export of processed waste for precious metal
recovery
…expected to rapidly change with formal
recyclers setting operations
5
Concerns: Informal Recycling
High-risk backyard operation
Non- efficient and Non-
environmentally sound technologies
Occupational and environmental
hazards
Loss of resources due to inefficient
processes
Impacts vulnerable social groups-
Women, children and mmigrant
labourers
