(a)
Interpretation:
Derive an expression for the mass generation rate of methane,
Concept introduction:
(b)
Interpretation:
A new landfill has a yield potential of
(c)
Interpretation:
The methane produced in three years
Calculate the value determined with this method and the percentage error in the calculation. Show graphically what the calculated value corresponds to on another sketch of
(d)
Interpretation:
Following amount 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 CH4 generated through the end of the third year.
(e)
Interpretation:
Explain in your own words the benefits of reducing the release of methane from landfills and of using the methane as a fuel instead of natural gas.
(f)
Interpretation:
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?
