Collecting the methane for use as a gaseous fuel rather than allowing it to be released to the atmosphere provides an alternative to natural gas as an energy source and has a beneficial effect on the environment. If a batch of waste with mass Maonnes) [1 tonne or 1 metric ton 1000 kg) is deposited in a landfill at t 0, the rate of generation of methane at a later time t is given by the following equation where Vau (SCM CH/y) methane generation rate ISCM m\'(STP)] K-rate constant ov), a measure of how fast the waste decomposes landfill gas yield potential [SCM onne wastel MNas tonnes of waste deposited at t 0 a. Explain in your own words the benefits ofreducing the release of methane from landfills and using the methane as a fuel instead of natural gas. b. Starting with the above equation, derive an expression for the mass generation rate of Madr)ltonnes CH without doing any calculations, sketch the shape of a plot of M vs t from t 0 to t 3y, and graphically show on the plot the total masses of methane generated in YEARS 1,2, and 3 CHint: Remember your calculus.) Then derive an expression for Mau (t)(tonnes CH), the total methane generated from t 0 to an arbitrary time t. c. A new landfill has a yield potential 100 SCM CH tonne waste and a rate constant k 0.04y 1. At the beginning ofits first year, 48,000 tonnes of waste are deposited. Calculate the tonnes of methane generated from this deposit over a three-year period d. Ajunior engineer solving the problem of Part c calculates the methane produced in three years from the 48,000 waste deposit as where M is given by the first expression derived in Part b.

Solution

a> methane should be used as a fuel instead of just releasing it from the landfills.

As mentioned methane is a powerful greenhouse gas so when it gets released in the atmosphere then it intreases the carbon dioxide content in the air .And this causes an imbalance in the air composition and this leads to global warming and the cloud cover that protects us from the harmful suns rays would weaken because of the excess CO2.

Hence its release should be decreased and it sould be used as a fuel.
