You need to understand how a sanitary land fill works!!! Not only do they need to be sealed so that nothing leaks out, but when it rains they collect water which needs to be pumped to a treatment system before it can be released into the environment. What is this contaminated liquid called? The second part to this question is: what layer is actually in contact with the garbage?

Effluent; clay
Leachate; sand
Sludge; subsoil
Slime; synthetic liner

Correct Answer

A. Leachate; sand

Explanation

Leachate is the correct answer for the first part of the question. Leachate refers to the contaminated liquid that is generated when water percolates through the waste in a landfill and picks up various pollutants. It needs to be pumped to a treatment system before being released into the environment.

For the second part of the question, the correct answer is sand. The layer that is actually in contact with the garbage in a landfill is typically a layer of sand. This layer helps to provide stability and support to the waste, as well as facilitate the movement and collection of leachate.

Bioremediation is an important tool to deal with hazardous waste. Which of the following a hazardous material that doesn't really work with bioremediation (biormediation doesn't help)?

Toxic metals
PCB's
Organic solvents
Diesel fuel
Gasoline

Correct Answer

A. Toxic metals

Explanation

Bioremediation is a process that uses living organisms or their byproducts to break down or remove pollutants from contaminated environments. However, toxic metals, such as lead, mercury, and arsenic, cannot be effectively remediated using bioremediation techniques. This is because these metals are not biodegradable and cannot be broken down by living organisms. Therefore, bioremediation does not work for toxic metals.

What happens to the garbage you put out on the street each week in your garbage bins? What percentage of MSW is burned in incinerators? (this it the question for the points - not the one above)

10%
50%
75%
16%
< 1%

Correct Answer

A. 16%

Explanation

Approximately 16% of municipal solid waste (MSW) is burned in incinerators. Incineration is a waste management method that involves the combustion of waste materials at high temperatures, converting them into ash, gas, and heat. This process can help reduce the volume of waste and generate energy through the heat produced. However, incineration also has environmental concerns, such as air pollution and the release of greenhouse gases. Therefore, it is important to consider alternative waste management methods, such as recycling and composting, to minimize the amount of waste sent to incinerators.

Read 21-3. This idea of industrial ecology is critical to sustainable society. The idea is similar to real food webs in natural ecosystems - where the waste of one is the starting material for another. Everything is connected and dependent on each other. Which of the following countries has a city that is a prototype of this type of industrial ecosystem?

Texas
FIJI
Germany
Denmark
Greenland

Correct Answer

A. Denmark

Explanation

Denmark has a city that is a prototype of this type of industrial ecosystem. The concept of industrial ecology, which is essential for a sustainable society, is based on the idea that waste from one industry can be used as a resource for another industry. This concept is similar to the interconnectedness and dependency seen in real food webs in natural ecosystems. Denmark has implemented this idea in the city of Kalundborg, where multiple industries exchange waste products and by-products to create a closed-loop system, minimizing waste and maximizing resource efficiency.

Read 21-4 and 21-5. This is a two part question. First of all which country has led the way in reuse by banning all beverage containers that cannot be reused. Secondly Which type of recycling would be exemplified by an aluminum can being melted down and reused to build another aluminum can?

Denmark; Primary recyling
Denmark: secondary recycling
Germany; Primary recycling
Germany; secondary recycling

Correct Answer

A. Denmark; Primary recyling

Explanation

Denmark has led the way in reuse by banning all beverage containers that cannot be reused. This means that Denmark has taken strict measures to ensure that all beverage containers are designed for reuse rather than being single-use items. Primary recycling refers to the process of converting waste materials into new products of the same type, and in this case, an aluminum can being melted down and reused to build another aluminum can exemplifies primary recycling.
