  1. Food waste management

  2. Food waste prevention

  3. Food waste recovery

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Food waste management encompasses a range of strategies to reduce, reuse, and recycle food waste. This includes practices such as composting, anaerobic digestion, and using food waste as animal feed.

Multiple choice

What is the term used to describe the process of converting food waste into biogas or other forms of energy?

  1. Anaerobic digestion

  2. Composting

  3. Recycling

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

Anaerobic digestion is a process in which organic matter, including food waste, is broken down by microorganisms in the absence of oxygen. This process produces biogas, which can be used as a renewable energy source.

Multiple choice

What is the term used to describe the process of converting food waste into compost, a nutrient-rich soil amendment?

  1. Anaerobic digestion

  2. Composting

  3. Recycling

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

Composting is the process of breaking down organic matter, such as food waste, into a nutrient-rich soil amendment. This process is carried out by microorganisms under controlled conditions.

Multiple choice

What is the term used to describe the process of converting food waste into a solid fuel source?

  1. Anaerobic digestion

  2. Composting

  3. Recycling

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

Pyrolysis is the process of converting organic matter, including food waste, into a solid fuel source through heating in the absence of oxygen.
