Money
is used generally by the public as a payment tool. The overused money can be damaged so it is unfit for use.
Therefore, every central banks around the country replaces the damaged money regularly and pile
them as trash. Hence, an environmental issue is generated; an excessive piling
of money waste.
On
the other hand, the use of coal and wood for industrial purposes also causes
its own environmental problems. Coal which has been relied upon as a source of
energy for the manufacturing process remains waste that is difficult to deal
with from its combustion. While the use
of firewood for large industrial demands a large amount of natural wood.
The
solution to these problems is to utilize waste paper money as an alternative
fuel. However, the problem is, (1) What
is the best way to produce briquettes of waste of money? (2) Can the effectiveness of briquette of
money waste compete with coal and firewood? (3) Will the price of money waste
briquettes be affordable and can be generally used?
We
do our research by testing the proxymate analysis and ultimate analysis of each
briquette we make, comparing money waste briqquete with firewood and coal by
doing combustion test, and doing a price
comparison analysis.
According
to our research, it is found that the best way to produce briquettes of money
waste is by using a pressing machine and by using a mixture of PVCa glue.
Because the result is more practical and neater. Compared with coal and firewood, waste
money briquettes is up to par. Besides being more environmentally friendly
because the ash level is low (4.74%), use of money waste briquettes for
industrial use also can save as much as 20% cost compared to firewood and 60%
cost compared to coal
