Multiple choice

Which of the following is NOT a common type of biomass feedstock?

  1. Wood

  2. Agricultural residues

  3. Animal manure

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

Fossil fuels, such as coal, oil, and natural gas, are not considered biomass feedstocks because they are not derived from organic matter.

Multiple choice

What is the primary product obtained from the gasification of organic materials?

  1. Biochar

  2. Syngas

  3. Compost

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

Gasification is a thermochemical process that converts organic materials into a gaseous mixture known as syngas. Syngas primarily consists of hydrogen, carbon monoxide, and carbon dioxide and can be used as a fuel or as a feedstock for various chemical processes.
