Self Evaluation Quiz - Waste Management - Quiz

It’s easy to flush a toilet or take out the trash without paying any attention to where your waste is going – and if it’s being disposed of in an environmentally friendly way. How much do you know about waste management?

Questions and Answers

1.

Kofiase, a suburb of Mampong has an average solid waste generation rate of 0.35kg/cap/day and an estimated population of 2,000. What is the annual waste generation rate of the community?
- A.
  
  700kg per annum
- B.
  
  0.7tons per annum
- C.
  
  256tons per annum
- D.
  
  256kg per annum
Correct Answer
C. 256tons per annum

Explanation
The annual waste generation rate of the community can be calculated by multiplying the average solid waste generation rate per capita per day (0.35kg/cap/day) by the estimated population (2,000) and the number of days in a year (365). This gives us 0.35kg/cap/day * 2,000 * 365 = 256,000kg per annum. To convert this to tons, we divide by 1,000, resulting in 256 tons per annum.

Which of the following statements best describes the composition of waste?
- A.
  
  The proportions of different items that make up the waste
- B.
  
  The proportions of waste from different sources that are discarded
- C.
  
  the amount of organic material present in the waste
- D.
  
  The proportion of recoverable materials present in the waste
Correct Answer
A. The proportions of different items that make up the waste

Explanation
The correct answer is "the proportions of different items that make up the waste." This statement best describes the composition of waste because it refers to the different items that are present in the waste and their respective proportions. It does not focus on the sources of waste or the amount of organic material or recoverable materials present.

The average waste generation rate of Mampong, is known to be 0.7kg/cap/day. This means that
- A.
  
  0.7kg of waste is produced at Mampong in a day
- B.
  
  One household in Mampong produces 0.7kg of waste in a day
- C.
  
  0.7kg of waste is collected from Mampong in a day
- D.
  
  One person in Mampong produces 0.7kg of waste in a day
Correct Answer
D. One person in Mampong produces 0.7kg of waste in a day

Explanation
The correct answer is "One person in Mampong produces 0.7kg of waste in a day". This is because the average waste generation rate is given as 0.7kg/cap/day, which means that each person in Mampong produces 0.7kg of waste in a day. This answer accurately reflects the information provided in the question.

A sample of waste weighs 2.5kg after drying at 105°C for 24 hours. If the waste weighed 3.2kg prior to drying, what is the moisture content of the waste?
- A.
  
  28%
- B.
  
  22%
- C.
  
  72%
- D.
  
  78%
Correct Answer
B. 22%

Explanation
The moisture content of the waste can be calculated by finding the difference between the weight before and after drying, and then dividing that difference by the weight before drying. In this case, the weight before drying is 3.2kg and the weight after drying is 2.5kg. The difference is 3.2kg - 2.5kg = 0.7kg. Dividing this difference by the weight before drying gives us (0.7kg / 3.2kg) * 100% = 21.875%. Rounding to the nearest whole number, the moisture content is approximately 22%.

Animal and vegetable waste resulting from the preparation of food is generally referred to as
- A.
  
  Refuse
- B.
  
  Litter
- C.
  
  Garbage
- D.
  
  Rubbish
Correct Answer
C. Garbage

Explanation
Animal and vegetable waste resulting from the preparation of food is commonly known as garbage. This waste includes leftover food, peels, scraps, and other organic materials that are discarded after cooking or eating. Garbage is typically collected and disposed of in waste management systems. Refuse, litter, and rubbish may also refer to waste materials, but they do not specifically pertain to food preparation waste.

The composition of waste that ends up at a disposal site cannot be affected by changes in the standard of living and economic status of the waste producers.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The composition of waste that ends up at a disposal site can be affected by changes in the standard of living and economic status of the waste producers. As people's standard of living improves and their economic status increases, they tend to consume more and generate more waste. This can lead to changes in the types of waste being produced, such as an increase in packaging waste or electronic waste. Therefore, the statement that the composition of waste cannot be affected by changes in standard of living and economic status is false.

The pollution potential of waste can be deduced from its composition.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The statement is true because the composition of waste can provide insights into its pollution potential. Certain materials or substances in waste can be more harmful to the environment or human health than others. For example, waste containing toxic chemicals or heavy metals may have a higher pollution potential compared to waste consisting of organic materials. By analyzing the composition of waste, it is possible to determine the level of pollution it may cause and take appropriate measures for its disposal or treatment.

As the level of development of a country increases, it is expected that the proportion of paper and organic waste in the municipal solid waste stream would also increase.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
As the level of development of a country increases, it is expected that the proportion of paper and organic waste in the municipal solid waste stream would decrease. This is because as countries develop, they tend to adopt more advanced waste management practices, such as recycling and composting, which reduce the amount of paper and organic waste that ends up in landfills. Additionally, developed countries often have stricter regulations and initiatives in place to promote waste reduction and encourage sustainable practices. Therefore, the proportion of paper and organic waste in the municipal solid waste stream is expected to decrease as a country develops.

A measure of household waste generation rates always provide an accurate estimate of the amount of waste that reaches the final disposal site.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement is false because a measure of household waste generation rates does not always provide an accurate estimate of the amount of waste that reaches the final disposal site. There are various factors that can affect the amount of waste that reaches the final disposal site, such as recycling efforts, waste management practices, and illegal dumping. Therefore, relying solely on household waste generation rates may not give an accurate estimate of the total waste that reaches the final disposal site.

Waste with high moisture content is not suitable for incineration.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Waste with high moisture content is not suitable for incineration because the high moisture content makes it difficult for the waste to burn effectively. Incineration relies on the combustion of waste materials, and moisture acts as a barrier to this process. The high moisture content can also lead to the production of more pollutants and emissions during incineration. Therefore, waste with high moisture content is not a suitable option for incineration.
