What is Electronics Waste?
 The term E-Waste applies to all wastes from or caused by
Electronics items.
 Electronics waste, “e-waste” or “Waste Electrical and
Electronics Equipment ”(“WEEE”) is a waste consisting of
any unwanted, obsolete or unusable electrical or electronics
equipment.
 E-waste includes computers, entertainment electronics,
mobile phones, and other items that have been discarded by
their their users.

How these become E-Waste?
Reasons:
Advancement in technology.
Changes in Style , Fashion & Status.
Nearing the end of there useful life.
Not taking precautions while handling them.

under ‘hazardous’ and ‘non-hazardous’ categories.

IMPACT
Effects on Human Health
• Damage to central and peripheral nervous system,
blood system and kidney damage.
• Affects brain development of children.
• Chronic damage to the brain.
• Asthmatic bronchitis.
• Reproductive and development problems.
• Lung cancer.
• Damage to heart, liver and spleen.
• Respiratory and skin disorders due to bioaccumulation
in fishes.

Effects on Environment
• Pollution of Ground – Water.
• Acidification of soil.
• Air Pollution.
• E-waste accounts for 40% of the lead and 75% of the
heavy metals found in landfills.

E-Waste disposal?
A Problem & Challenge !!!
• Landfill disposal allows heavy metals to leach into ground water.
• Incineration make hazardous material airborne.
• Acid baths are dangerous and caused water and soil
contamination.
• Exported materials are handled improperly.
( Most e-waste goes to China , India & Africa)
Method of treatment & disposal:
• Landfill
• Incineration
• Pyrolysis
• Recycle & Reuse

Recycling of E-Waste
Disassembly/dismantling
Disassembly is the systematic removal of components , a group of
parts or a subassembly from a product which is in E-Waste.
Upgrading:
It includes comminuting and separation of materials using
mechanical / physical and /or metallurgical processing. Methods
to recover materials include incineration and refining.
Material Recovery:
The material are recovered recycling facilities. The plastics , glass
metals can be recovered by sorting them before mixing with other waste.

What can you do?
 In order to lessen the amount of e-waste being
produced , individuals can do many things:
1. Keep your old electronics longer instead of replacing
item
2. If discarding old electronics , be sure to recycle them at
a trusted recycling center.
3. Purchase efficient materials such that do not contain
hazardous materials such as mercury and lead.

Conclusion :
 As far as e-waste is concerned , it has emerged as on of the
fastest growing waste streams world wide today.
 Electronic equipment is one of the largest known sources of
heavy metals without effective collection , reuse and
recycling systems , they will be dangerous to environment.
 Reuse and recycling of electronic equipment is a beneficial
alternative than disposal.
 Awareness of e-waste.
 Implementation of legislation.
