Present
Situation of e waste management in INDIA

India(5th largest e waste producing country in world),
with the growth of 30% p.a., is estimated to generate 52 lakh metric tonnes of
e waste by 2020.Largest waste producing states are Maharashtra, Tamil Nadu,
Uttar Pradesh, primarily cities of Mumbai(11,000
tons),
Delhi(9,750
tons),
Bangalore(4,650 tons),
Chennai(4,100 tons).
India imports e waste from countries like the US(ranked top 42% followed by)
China(30%), European Union(EU-18%)(10% other countries –south Korea, japan
,Taiwan) according to study of Assocham(Associated
Chambers of Commerce and Industry of India).

Steps that can be used or currently being
implemented to manage e-waste are:

1)     Buying
gadgets with multiple uses.

2)     Donation
of used electronics to social programs.

3)     Reuse
parts of the electronics to build other gadgets(reclaim parts after
dismantling)

4)     Recycle
electronics and batteries.

5)    
Usage of Cloud system instead
of syncing and backing up files in hard disks.

E waste consists of metals like cadmium, lead,
mercury, nickel, silver, lithium (cell phone batteries), gold. Dismantling,
crude handling and disposal of highly toxic e-waste can affect people in large
numbers through contaminated soil and polluted surface and ground water having
serious implications like nervous breakdown and damage of vital organs.

Average PC of approximately 3.15
kg weight contains:

7.24 kg – Plastics       1.98 kg – Lead                        0.693 g – Mercury      0.409 g – Arsenic

2.961 g – Cadmium    1.98 g – Chromium     9.92 g – Barium          4.94
g – Beryllium

RECYCLING E-waste

Current procedures used in India
for recycling e-waste are:

1.    
Dismantling:
Electronic waste, especially printed wiring boards, cathode ray tubes,
condensers, plastics are dismantled.

2.    
Hammering: Rag
pickers use hammers to break old computers and burn them.

3.    
Refining and
conditioning: Other e-waste fractions are processed to directly reusable
components and to secondary raw materials in different refining and
conditioning processes.

4.    
Shredding: Conventional
method employed is mechanical shredding and density separation using water but
the recycling efficiency is quite low.
