Every year, millions of phones in India and over trillions all around the world are dumped. But what one doesn't think is the adverse effect of all this, and the damage to our environment this all causes. This presentation enlists all of them, and also explains what are the minor changes we can make in the manufacturing materials list of our mobile phones which can possibly make them more environment-friendly.

2. ACKNOWLEDGEMENT
I would like to express my gratitude and appreciation to all those who gave me the possibility to
complete this report. A special thanks to my department teachers, whose help, stimulating
suggestions and encouragement, helped me in preparing this report. I would also like to thank
my Chemistry Teacher who helped me to do this research.
This opportunity to do research on the topic “Greener Mobile Phones” enhanced my knowledge a
nd concepts of Sciences. I am really thankful to them.

4. WHAT
IS
E-WASTE?

5. E-WASTE
 e-waste - term for electronic products that have become unwanted, non-working or obsolete and
have essentially reached the end of their useful life.
 main reason for being obsolete - technology advancement at
such a high rate.
 thus, many electronic devices become “trash” after a short use.
 old electronic items contribute to e-waste such as VCRs being
replaced by DVD players, and DVD players being replaced by
Blu-ray players.

6. E-WASTE
 Annual global e-Waste production is pegged at approximately 50 million metric tonnes.
 India - fifth biggest producer of e-waste in the world, discarding 1.7 million tonnes of electronic
and electrical equipment in 2014, e-waste is likely to rise by 21 per cent in next three years.
 Best way to deal with E-Waste – 3 R’s

7. THE TRUTH
 Despite a wide range of environmental legislation in India there are no specific laws or guidelines
for electronic waste or computer waste.
 Recycling electronics isn’t like recycling cardboard. These products are not easy to recycle.
Proper and safe recycling often costs more money than the materials are worth.
 Barely 4% of the e-Waste produced
in India is recycled.
 The rest goes to landfills and incinerators.

13. BASIS OF THE RESEARCH
 All the components stated are full of toxic chemicals
and compounds.
 Which can lead to severe damage to human beings plus
environment if just simply thrown away.
 Research work – a decent attempt to find a replacement
from the periodic table which are less damaging to our
nature on disposing off.
 But without causing much difference in their efficiency.

17. CONCLUSION
These alterations are capable of reducing the toxicity of our devices by a large
amount without causing any noticeable difference in their efficiency.
But since these changes are not tested in real life till now, so nothing concrete
can be stated right now.
Once we get sure about them, we can get these pass through a pilot stage.

18. FUTURE
There are still some materials which are required to be replaced like:
 Mercury used in LCDs
 Lead used in PCBs, and
 other heavy metals and hazardous
materials like Cadmium and Lithium
Because being the new generation of our
country, it’s our duty to keep our environment
as one of our top priorities while making a
new invention or innovation.
SO WE CAN’T SAY THAT IT’S AN END, BUT JUST THE BEGINNING.
