Life time of the plastic cups is quite

calculations are made assuming
cups are changed every year.
initial investment of Rs. 7000 for
melamine cups
25 trees a month
Total cups used per day= 200 (based on survey report)
Total cups used per month= 200*30= 6000 cups.
Trees required to make one paper cup= 6.5 million/16 billion
=0.0040625 trees
Therefore, in a month trees used= 0.0040625x6000 = 24.375
Therefore, approximately we use 25 trees per month
Over 6.5 million trees were cut down to make 16 billion paper cups used
by US consumers only for coffee in 2006, using 4 billion US gallons
(15,000,000 m3) of water and resulting in 253 million pounds of waste.
Overall, North Americans use 58% of all paper cups, amounting to a
staggering 130 billion cups.
Source : http://en.wikipedia.org/wiki/Paper_cup
Water used to make one paper cup=150
billion litres/16 billion= 9.375 litres
In a month water used to make 6000
cups=56250 litres
Water used to wash 200 cups for a month = 1500 litres per month ( based on survey results)
Cost of one paper cup = Rs.
Therefore in a year total cups used= Rs.36000.
Therefore, total cost for one year = Rs. 36000
One melamine cup costs= Rs. 35
Therefore 200 Melamine cups=Rs.7000
(statistics for one year)
Bone china mugs have already been tried in the mess. But they didn’t work because of their brittle nature.
Food scientists in the U.S. say that
there are melamine products in
which it’s safe to cook and serve,
but because of inadequate labeling
it’s almost impossible to tell the
safe products from those that can
release formaldehyde.
Therefore choose the right
material for no harmful effects!
