  1. Anaerobic digestion

  2. Aerobic digestion

  3. Pyrolysis

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

Anaerobic digestion is the process of converting organic waste into biogas, a renewable energy source, in the absence of oxygen.

Multiple choice

What is the term for the process of converting waste into a liquid fuel?

  1. Pyrolysis

  2. Gasification

  3. Hydrothermal liquefaction

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

Hydrothermal liquefaction is a process where waste is converted into a liquid fuel through a thermochemical reaction in the presence of water at high temperatures and pressures.

Multiple choice

What is the term used to describe the process of removing sediment from wine before bottling?

  1. Decanting

  2. Fining

  3. Aeration

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

Filtration is the process of removing sediment and impurities from wine before bottling. This is typically done using a filter made of cellulose or diatomaceous earth, which allows the wine to pass through while trapping the unwanted particles.

Multiple choice

What is the term used to describe the process of removing the cork from a wine bottle?

  1. Decanting

  2. Aeration

  3. Corking

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

Uncorking is the process of removing the cork from a wine bottle. This is typically done using a corkscrew, which is inserted into the cork and twisted to extract it from the bottle.
