Methane, a powerful greenhouse gas, is generated via the anaerobic decomposition of solid waste in landfills. 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 M(tonnes) [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 V CH4 (t) = kL o M waste e -kt where: V CH4 (SCM CH 4 /y) = methane generation rate [SCM = m 3 (STP)] K = rate constant (y -1 ), a measure of how fast the waste decomposes L o = landfill gas yield potential [SCM CH 4 /tonne waste] M waste = tonnes of waste deposited at t= 0
a. Explain in your own words the benefits of reducing 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 M CH4 (t)[tonnes CH 4 /y]. Without doing any calculations, sketch the shape of a plot of M CH4 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 (Hint: Remember your calculus.) Then derive an expression for M CH4 (t)(tonnes CH 4 ), the total methane generated from t =0 to an arbitrary time t.
c. A new landfill has a yield potential L o = 100 SCM CH 4 /tonne waste and a rate constant k = 0.04y -1 . At the beginning of its first year, 48,000 tonnes of waste are deposited. Calculate the tonnes of methane generated from this deposit over a three-year period.
d. A junior engineer solving the problem of Part c calculates the methane produced in three years from the 48,000 waste deposit as M CH4 (t=3) = M CH4 (t=0){tonnes CH 4 /y}x 1y + M CH4 (t=1)x1 + M CH4 (t=2)x1 where M CH4 is given by the first expression derived in Part b.
-- -- -- Briefly state what the engineer is assuming about the rate of methane generation
-- -- -- - Calculate the value she would determine and the percentage error in her calculation, and show graphically what the calculated value corresponds to on another sketch of M CH4 vs t.
-- -- - The answer to Part c is 390 tonnes CH 4 . When one of the text authors first did the calculation of M, the result was 210 tonnes CH 4 . The author immediately knew that something had to be wrong in the calculation. Explain her reasoning.
e. The following amounts of waste are deposited in the landfill on January 1 in each of three consecutive years: Waste (tonnes) Year 1 48,000 Year 2 45,000 Year 3 54,000 Calculate the metric tons of methane generated through December 31 of the third year.
f. One way to avoid the environmental hazard of methane generation is to incinerate the waste before it has a chance to decompose. What problems might this alternative process introduce?

Analysis and Interpretation of Liquidity and Solvency
Balance sheets and income statements for Costco Wholesale Corporation follow.

(a) Compute Costco's financial leverage (FLEV), Spread, and noncontrolling interest (NCI) ratio for 2016; recall, NNE = NOPAT-Net income.

Remember to use negative signs with answers, when appropriate.  

2016 NNO =$Answer

million
2015 NNO =$Answer million  

2016 NNE =$Answer

million
2016 NNEP =Answer% Round NNEP to two decimal places.   

2016 FLEV        = Answer  Round FLEV to four decimal places.   
2016 Spread    = Answer% Round Spread to two decimal places.
2016 NCI ratio = Answer Round NCI ratio to four decimal places.

(b) Assume that Costco's return on equity (ROE) for 2016 is 20.71% and its return on net operating assets (RNOA) is 20.66%. Confirm computations to yield the relation: ROE = [RNOA + (FLEV X Spread)] X NCI ratio.

2016 ROE =Answer

% = [Answer%+(Answer X Answer%)] X Answer


(c) What do your computations of the nonoperating return in parts (a) and (b) imply about the company's use of borrowed funds?

Costco's FLEV is negative - meaning its non-operating assets exceed its non-operating liabilities. Costco has a high level of short term investments to use for new opportunities.

Costco's FLEV is negative - meaning its non-operating liabilities exceed its non operating assets. Costco will need to rely on debt to finance new opportunities.

Costco's FLEV is positive - meaning its non-operating assets exceed its non-operating liabilities. Costco has a high level of cash and short term investments to use for new opportunities.

Costco's FLEV is positive - meaning its non-operating liabilities exceed its non-operating assets. Costco has a high level of cash and short term investments to use for new opportunties.
