5. Some Facts from the World of Mobile Communication
 100,000 cell phones = 2.5 Kg Au + 25 Kg Ag + 1000 Kg Cu
 Total number of Mobile devices (Cell +Tab ) by 2015 = 2,000,000
 1000 gms of SIM Card = 1.75 gms Au
 A recent innovative technique is being used to capture gold from e-
waste is using fungi. - A study by Finnish Research Group

completely self-contained
in a transportable shipping
container.
Crushed CRT glass,
coated with lead,
ready for processing by
a lead smelter.

11. Other components from main
equipment are separated and sold
as commodities to various
recyclers.

13. Government Responsibility
Need for stringent health standards and environmental protection
laws in India,
Extended producer responsibility,
Import of waste under license,
Producer-public-government cooperation,
Awareness program, following safer and efficient methods
