Consider the following materials:

1. Agricultural residues
2. Corn grains
3. Wastewater treatment sludge
4. Wood mill waste

Which of the above can be used as feedstock for producing Sustainable Aviation Fuel?

1. 1 and 2 only
2. 2 and 4 only
3. 1, 2, 3 and 4
4. 1, 3 and 4 only

Explanation

All are correct

• Also known as Bio-Jet Fuel, Sustainable Aviation Fuel (SAF) is a carbon-reduction solution that is available for use in aircraft and helicopters. It is a “drop-in” fuel that can be blended up to 50% with traditional jet fuel. Its chemical and physical properties are similar to conventional jet fuel. It can be used in existing aircraft engines without modifications and can be blended with conventional jet fuel, making it relatively easy to integrate into existing aviation infrastructure.
• Feedstocks for SAF:
  • Corn grain
  • Oil seeds
  • Algae
  • Agricultural and forestry residues
  • Wood mill waste
  • Municipal solid waste streams
  • Wet wastes (manures, wastewater treatment sludge)
