  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.
