Consider the following materials:
- Agricultural residues
- Corn grain
- Wastewater treatment sludge
- Wood mill waste
Which
of the above can be used as feedstock for producing Sustainable Aviation Fuel ?
(a). 1 and 2 only
(b). 3 and 4 only
(c). 1, 2, 3 and 4
(d). 1, 3 and 4 only
Explanation:
All of the listed materials can be used
as feedstock for producing Sustainable Aviation Fuel (SAF).
●
Agricultural residues: These
include materials like corn stalks, wheat straw, and rice husks, which can be
converted into biofuels.
●
Corn grain: While corn is often
used for food and ethanol production, it can also be a feedstock for SAF.
●
Wastewater treatment sludge: This material
contains organic matter that can be processed into biofuels.
●
Wood mill waste: Sawdust and other
wood byproducts can be converted into biofuels, including SAF.
The use of these materials as feedstock
for SAF contributes to reducing greenhouse gas emissions and promoting
sustainability in the aviation industry
Therefore, the answer is option (d).
