Study suggests more cost-efficient method for SAF production

In Georgia, The University of Georgia (UGA) reported that a new research from the UGA noted that biofuel generated from logging residues could make switching to sustainable aviation fuel more cost-efficient and carbon friendly than previously thought.

In a recent journal article Puneet Dwivedi, a professor of sustainability sciences in the Warnell School of Forestry and Natural Resources, proposed developing SAF from logging residues generated during forest harvests and thinning operations in Georgia, the largest forestry state in the country.

This study focuses on the environmental and economic impacts of SAF production from logging residues in Georgia. By analyzing two production methods, Ethanol-to-Jet (ETJ) and Iso-Butanol-to-Jet (Iso-BTJ), the study estimates the life cycle carbon emissions and unit production costs associated with SAF.

UGA noted that most logging operations in Georgia take place on private land in partnerships between landowners and companies. Dwivedi noted the environmental concern of cutting down trees, but he pointed out that after the trees are harvested, the landowners would replant the harvested area for starting the next round of forest management.

With a large forestry base and home to Hartsfield Jackson Airport, the busiest airport in the world, Georgia could be the perfect place to begin SAF operations, Dwivedi said.
