Multiple choice

What is the process of turning organic waste into a nutrient-rich soil amendment called?

  1. Recycling

  2. Composting

  3. Incineration

  4. Landfilling
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Composting is the process of turning organic waste, such as food scraps, yard waste, and paper products, into a nutrient-rich soil amendment. Composting helps to reduce the amount of waste sent to landfills and incinerators.

Multiple choice

What is the term for the process of extracting valuable materials from waste?

  1. Recycling

  2. Composting

  3. Incineration

  4. Landfilling
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Recycling is the process of extracting valuable materials from waste and converting them into new products. Recycling helps to reduce the amount of waste sent to landfills and incinerators, and it also conserves resources.

Multiple choice

What is the term for the process of burning waste at high temperatures?

  1. Recycling

  2. Composting

  3. Incineration

  4. Landfilling
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Incineration is the process of burning waste at high temperatures. Incineration is sometimes used to reduce the volume of waste and to generate energy, but it also produces air pollution and ash.

Multiple choice

What is the term for the process of disposing of waste by burying it in the ground?

  1. Recycling

  2. Composting

  3. Incineration

  4. Landfilling
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Landfilling is the process of disposing of waste by burying it in the ground. Landfilling is the most common method of waste disposal, but it can also be the most harmful to the environment.

Multiple choice

What is the term for the process of reducing the amount of waste produced?

  1. Recycling

  2. Composting

  3. Incineration

  4. Waste reduction
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Waste reduction is the process of reducing the amount of waste produced. Waste reduction can be achieved through a variety of methods, such as buying less, using less, and reusing items whenever possible.

Multiple choice

What is the term for the process of converting organic waste into biogas?

  1. Recycling

  2. Composting

  3. Anaerobic digestion

  4. Landfilling
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Anaerobic digestion is the process of converting organic waste into biogas, which is a mixture of methane and carbon dioxide. Anaerobic digestion is a sustainable way to manage organic waste because it produces renewable energy and reduces the amount of waste sent to landfills.
