MEE5901 Columbia Southern Solid Waste and Solid Waste Management Summary Instructions: The siting of a landfill is always contentious in a community due to operational issues with traffic and odors, and if you live close to the landfill you may deal with a decline in property values. Landfills will eventually generate leachate that can adversely impact the environment if the liner is breached, bringing toxicity to vegetation and contamination to ground water. Having a properly operating landfill can minimize many of these impacts to citizens and to the environment. This assignment will further explore these topics.

Problem:
A community generates 175 tons of municipal solid waste (MSW) per year. What is the actual
average annual production of methane that a community should expect from the landfill
operation in BTU per year?
Solution:
According to the Worrell, Vesilind, and Ludwig (2017),
In theory, the biological decomposition of one ton of MSW produces 15,600 ft3 (442
m³) of landfill gas containing 55% methane (CH4) and a heat value of 530 Btu/ft3
(19,730 kJ/m3). Since only part of the waste converts to methane, due to moisture
limitation, inaccessible waste, and non-biodegradable fractions, the actual average
methane yield is closer to 3,900 ft3/ton.” (p. 347)
Therefore:
BTU/year = 175 ton x 3,900 ft3 x 530 BTU = 361,725,000 or 361 x 106 BTU/year

ft3
[Please note how the units “ton” and “ft3” cancel out and we are left with “BTU” and “year” as
our final units]

Leachate Treatment and Disposal
In wet areas, leachate treatment, use, and disposal represents one of the major
expenses of landfill operations—not only during the active life of the landfill but
also for a significant period of time after closure. Due to the cost implications, con-
siderable attention must be given to selecting the most environmentally responsible,
cost-effective alternative for leachate treatment and disposal. The optimal treatment
solution may change over time as new technologies are developed, new regulations
are promulgated, and/or leachate quality varies as a function of landfill age.
Leachate-treatment needs depend upon the final disposition of the leachate.
Final disposal of leachate may be accomplished through co-disposal at a wastewa-
her treatment plant or through direct discharge
, both of which could be preceded
by on-site treatment. Leachate treatment is often difficult because of high organic
strength, irregular production rates and composition, variation in biodegradabil-
ity, and low phosphorous content (if biological treatment is considered). Several
authors have discussed leachate treatment options, 29-32 which are briefly summa-
rized in Table 8-11. Generally, where on-site treatment and discharge is selected,
several unit processes are required to address the range of contaminants present.
New York uses polymer coagulation, flocculation, and sedimentation, followed
by anaerobic biological treatment, two-stage aerobic biological treatment, and
a leachate treatment facility at the Al Turi Landfill in Orange County,
