e waste management

1. Seminar on E-waste management

3. E-WASTE MANAGEMENT
• E-waste is any electrical or electronic
equipment that’s been discarded. This
includes working and broken items that are
thrown in the garbage or donated to a charity
reseller like Goodwill. Often, if the item goes
unsold in the store, it will be thrown away. E-
waste is particularly dangerous due to toxic
chemicals that naturally leach from the metals
inside when buried.

4. IMPORTANT CONCERN OF
DISCARDING e-waste
• While discarding e-waste u should be careful
about the data stored in discarded storage
devices
• It’s very important that you delete the data
stored in discarded devices because it can be
misused by anyone

5. The improper disposal of electronic
products leads to the possibility of
damaging the environment. As more e-
Waste is placed in landfills, exposure to
environmental toxins is likely to increase,
resulting in elevated risks of cancer and
developmental and neurological
disorders.

6. E-WASTE DISPOSAL PROCESS
• E – waste is categorized by the government of
India under the broad class of hazardous waste
within e- waste there are several categories such
as large and small household appliances ,electric
and electronic toys etc
• Composition of e-waste : electric and electronic
equipment contains metallic and non metallic
elements alloys and compounds such as copper,
aluminum, gold , silver, nickel ,iron etc.

7. Procedure for recycling and recovery
 Dismantling : removal of part containing
dangerous substance (CFC , Hg switches, PCB)
Removal of easily accessible parts containing
valuable substance(cable containing copper
,steel ,iron etc.
 Segregation of ferrous metal ,non ferrous metal
and plastic : this separation is normally done in
a shredder process(The shredding process
produces raw material to be re-introduced into
manufacturing, as well as finished products )

8.  Refurbishment and reuse : refurbishment and reuse of e-
waste has potential for those used electrical and electronic
equipments which can be easily refurbished to put to its
original use .
Recycling/disposal of valuable materials : ferrous metals in
electrical are furnaces ,non – ferrous metal in smelting plant
,precious and metals in separating works.
 Treatment/disposal of dangerous material and waste :
shredder light fraction is disposed off in landfill sites or
sometimes expensive , chlorofluoro- carbons are treated
thermally , printed circuit board (PCB) is disposed off in
underground storages ,mercury is often recycled or disposed
off in underground landfill sites.
