MEE 5901, Advanced Solid Waste Management
Unit V Assignment
This assignment will allow you to demonstrate the following objectives:
➢
➢
Assess the fundamental science and engineering principles of solid waste management.
Examine the impact of solid waste on human populations.
Instructions: Biological treatment of municipal wastes are the primary means for degrading organic
matter and for stabilizing the contents of the landfill. Both aerobic and anaerobic processes are
functioning in landfills and compost piles. The majority of regulations are set up to protect these biological
populations from being killed off or limited in their ability to complete the degradation cycle. The methane
by-product can be used as an energy source to help reduce operating costs and to limit the release of a
very strong greenhouse gas into the environment. This assignment will allow you to further explore these
concepts.
Answer the questions directly on this document. When you are finished, select “Save As,” and save the
document using this format: Student ID_Unit# (ex. 1234567_UnitI). Upload this document to BlackBoard
as a .doc, .docx, or .rtf file. The specified word count is given for each question. At a minimum, you must
use your textbook as a resource for these questions. Other sources may be used as needed. All material
from outside sources (including your textbook) must be cited and referenced in APA format. Please
include a reference list after each question.
1) Navigate to the CSU Online Library and review some articles on landfills and on compost piles. This
assignment is not about summarizing these operations but about analyzing and comparing the
differences between these two fundamental principles of solid waste management. Describe when
and why each of these fundamentals is appropriate for use to manage municipal solid waste. Include
in your discussion details about the differences of microbial mechanisms, the end products of
degradation, and factors that help and harm the performance of these operations. How effective is
each one? (Your total response for all parts of this question should be at least 500 words.)
2) A community of 62,000 does not have a municipal recycling program, and it sends all of its refuse to
the municipal landfill. Will the landfill generate enough natural gas to meet the needs of the city if the
municipality needs to annually generate 10 million cubic meters of natural gas (methane) and the city
collects all of the methane that is generated? How will this affect the population of the city? Explain
your answer. (Your total response for all parts of this question should be at least 300 words.)

PROBLEM:
A community of 50,000 people do not have a municipal recycle program and they send all of
their refuse to the municipal landfill. Will the landfill generate enough natural gas to meet the
needs of the city, if the municipality needs to annually generate 15 million cubic meters of
natural gas (methane) and the city collects all of the methane that is generated?
Additional information:
* Each resident generates 4.38 lbs. of refuse per day (see p. 43)
* Each pound of refuse generates 257 liters of methane (see p. 239)
SOLUTION:
To calculate the quantity of methane

**See below for additional steps (if needed)
= 9,318,292.948 𝒎𝟑
Therefore, approximately 9.3 million m3 of natural gas is produced per year. No, the
landfill will not generate enough natural gas to meet the needs of the municipality.
** This is the in-between steps to get the final answer. We multiply across all numerators, and
then divide:
