What is E-waste
 Electrical and electronic equipment.
 Intended to be discarded.
 EXAMPLE: computers, computer peripherals , televisions ,
VCRs , DVD Players, stereo equipment.
Production of E-Waste Producer, consumer or bulk consumer.
 Annual global E-Waste production - 50millions metric
tonnes.
 1.5 lakh tonnes of E-waste by 2020-India.
Composition of E-Waste
Disposal of E-waste
 Due to the high financial investment - a high level of trans
boundary, often illegal, movement of e-waste into developing
countries.
 Between 50% & 80% of e-waste in developed countries each
year is being exported.
Problems of E-Waste
 Products - Obsolete and Discarded
 This is coupled with explosive sales in consumer
electronics.
 More products are being disposed.
 Electronics - Difficult To Recycle
 Proper and safe recycling -costs more money
Problems of E-Waste
 Electronics are not designed for recycling
 Physical designs make recycling challenging.
 “Green electronics,”- we are a far way from truly green
products.
 Electronics contain many toxic materials
 Monitors and televisions - 4 and 8 pounds of lead in
them.
 About 40% of the heavy metals- in landfills come from
electronic equipment.
Health Problems of E-Waste
 The gases released during the burning e-waste
 PVC- dangerous for both live creatures & atmosphere.
 Inhalation of open burning emissions.
 If open fires burn with a lack of oxygen, it forms
carbon monoxide, which poisons the blood when
inhaled.
Management of E-waste
 There are several steps to recycle or reuse the e-
waste. They are listed below:
 Detoxication
 Shredding
 Refining
DETOXICATION
 Detoxication - process of removing critical components
from the e-waste.
 Critical components -lead glass ,CFC gases,and batteries.
SHREDDING
 Electronic materials are broken into pieces.
 The mechanical processing plants includes shredders,
crushing units, magnetic and air-separators.
 The emitted gases are filtered to minimize
environmental impact.
REFINING
 To obtain reusable components.
 Refining of resources in e-waste is possible.
 Most of the components need to be refined before
they can be sold as secondary raw materials
