ACKNOWLEDGEMENTI would like to express my gratitude and appreciation to all those who gave me the pos-sibility 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 re-search.This opportunity to do research on the topic “Greener Mobile Phones” enhanced my knowledge and concepts of Sciences. I am really thankful to them.

WHAT IS

E-WASTE?

E-WASTE e-waste - term for electronic products that have become unwanted, non-working or obso-

lete 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.

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 elec-tronic and electrical equipment in 2014, e-waste is likely to rise by 21 per cent in next three years.

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 recy-cle. 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.

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.

CONCLUSIONThese 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.

FUTUREThere 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.
