More than 20 million computers are thrown out
every year world wide, very few are recycled
More than 200 million computers shall be obsolete
world wide within a next few years
Same is true for many other electronic goods.

Problems with Electronic Industry

Designers are not responsible for end of life design
Product manufacturing does not consider the entire
life time of the product
Designers are not responsible for end of life design

Result is waste – economically inefficient,
environmentally harmful, socially irresponsible
UNSUSTAINABLE
What to do with such a huge amount of e-waste?

Each time a Google search is generated at the user’s
computer, the carbon dioxide footprint is 0.2 g of CO2
per search.

About 1.2% of total fossil-duel based carbon
emission

Greenhouse gases….
Global Warming….. Polar
Ice caps melt…. Sea level
rises….. Many islands and
countries shall get wiped
out…..

The Earth is finite……..

So are the natural resources……..

SHORTAGE OF FRESHWATER

India is destined to face critical stress on drinking water by the year 2025 along with 48 other countries. 31 of them
are already water stressed.
By the year 2050 about 4 billion people shall be seriously
affected by water...
