waste management program

You are required to select any two topics from the following 15 topics that you would like to
do. Students are required to submit each report as hard copy and upload a soft copy using
Turnitin assignment at UTSOnline.
1. Describe the local solid waste management program in your residential area. Evaluate the
advantages and disadvantages of the current program.
2. Draw a simple diagram of the solid waste collection route in your residential area. What
are the important steps for establishing the solid waste collection routes? What do we
need to consider when laying out collection routes?
3. People may have different opinions on waste recycling and reuse. Find out the debate
information on why “Recycling Is Garbage”. Do a small survey (20-30 people) and find
out how people feel about the importance of waste recycling and reuse (i.e. whether it’s
really necessary).
4. Read the information online about “Is Human Activity Primarily Responsible for Global
Climate Change?” (http://climatechange.procon.org/). What is your position on the
climate-change debate? Explain why.
5. Explain why noise prevention and attenuation is importance for civil and environmental
engineering works. What noise mitigation strategies are currently used in construction
sites? Evaluate the advantages and disadvantages of current methods.
6. Assume that you are acting as a manager on a landfill site. The landfill activity has been
completed and your responsibility is to monitor the key parameters of the landfill. To
take the postclosure care, explain what should be monitored and why they need to be
monitored for the landfill.
7. The Woodlawn site is located 250 km south of Sydney, near Goulburn in New South
Wales. It was previously used as a copper, lead, and zinc open-cut mine and currently
used as one of the largest landfill bioreactor projects in the world.
After separating certain types of organics from mixed household waste for composting
purpose, the remaining of the waste goes through anaerobic digestion to produce
methane, which is used as fuel to generate electricity. Last ten years over 4 million
tonnes of waste has been turned into 34.5 million cubic meters of methane, and the
current capacity is 22.5 MW/day.
(a) Describe the process of the landfill bioreactor.
(b) List the advantages of this bioreactor over the conventional landfill system.
More detail on:
8. On 21 February 2005, the Leuwigajah dumpsite, Bandung in Java, Indonesia was
affected by a large waste slide due to heavy rainfall. It was the second deadliest waste
slide in history, which buried 71 houses and killed 143 people.
(a) Find out the reasons for this waste slide
(b) What preventive measures that could have been applied to avoid this accident.
9. According to the environmental report of Campbelltown City Council, 21,145 tonnes of
waste was dumped into landfill in 2012, while 40,469 tonnes of waste was disposed into
landfill in 2016 due to 91% increase in waste disposal rate. It is estimated that the figure
will increase up to 77,000 tonnes in 2017.
To deal with this problem, an additional landfill site has been chosen at Picton, 36 km
away from Campbelltown. The nearest school was 34 km, and closest residential area
was 28 km away from the site chosen for landfill. Additional information shows the local
market and a lake is 5 and 7 Km away respectively from the proposed landfill site.
Evaluate the environmental and social impacts of the proposed landfill site.
10. Landfills may be designed with single or double liners constructed by soil, clay,
geomembrane, plastic etc. Consider a landfill site where hazardous waste is disposed.
1) What would be the suitable design of liner system for this landfill?
2) Justify the function of leachate collection system from this particular type of landfill.
11. Research about the waste management issues related to major processes (for example,
pulping, thickening and bleaching) included in Paper & Pulp industry. Identify major
pollutants in these steps and the corresponding treatment strategies.
12. Research about the current state of hazardous waste management of acid mine drainage
in coal manufacturing industry in Australia and describe what factors affect the
management and why.
13. Radioactive waste: Issues with sources and treatment. Give 2 examples of
states/nations/governments that manage this well.
14. E-waste: What are the socio-economic and environmental issues? Give 2 examples of
states/nations/governments that manage this well.
15. Polychlorinated biphenyls (PCBs) have been shown to cause cancer in animals and
evidence supports a cancer-causing effect on humans. Research about accidents related to
PCBs: Issues and effects. Give 2 case studies.
