Multiple choice

Which of the following is not a common type of waste recycling technology?

  1. Mechanical recycling

  2. Chemical recycling

  3. Incineration

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

Incineration is a waste disposal method that involves burning waste to generate energy. It is not considered a recycling technology as it does not result in the recovery of materials for reuse.

C Correct answer
Explanation

Composting is a biological process that involves the decomposition of organic waste by microorganisms, resulting in a nutrient-rich soil amendment.

Multiple choice

Which type of recycling technology involves the separation of different materials from a waste stream?

  1. Mechanical recycling

  2. Chemical recycling

  3. Sorting

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

Sorting is a mechanical process that separates different materials from a waste stream, such as paper, plastic, metal, and glass, for further recycling.

Multiple choice

Which type of recycling technology involves the use of heat to break down waste materials?

  1. Mechanical recycling

  2. Chemical recycling

  3. Pyrolysis

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

Pyrolysis is a thermochemical process that involves the decomposition of waste materials through the application of heat in the absence of oxygen.

Multiple choice
