Delta Air Lines is pursuing a plan to convert shuttered pulp mills across Georgia into sustainable aviation fuel biorefineries, with the dual aim of securing local feedstock and keeping commercial timberland in production, according to Atlanta News First.

The concept, framed by the outlet as "from shuttered mills to jet engines," would repurpose decommissioned wood-processing facilities rather than build greenfield plants, leveraging existing rail spurs, power interconnections, and mill-experienced workforces.

What does Delta actually propose?

Atlanta News First's report does not name specific sites, identify partners, cite capacity figures, or confirm a commissioning date. The headline points to a mill-conversion strategy that would repurpose existing industrial assets, an approach that compresses the permitting and construction timeline typical of new biofuel capacity.

Delta has previously signaled broader SAF ambitions through offtake agreements with conventional producers. A Georgia woody-biomass project would mark a geographic and technical departure from those arrangements, which have historically drawn on Midwestern ethanol and coastal waste-oil streams.

Why shuttered mills, and why now?

Georgia's pulp and paper sector contracted sharply over the past two decades as global demand for graphic papers fell and producers consolidated. The resulting inventory of idled sites carries unusual value for a biorefinery developer: zoned industrial land, established utility connections, and host communities familiar with process-plant operations. Repurposing these assets sidesteps the greenfield permitting timeline that typically slows biofuel capacity additions.

Can forestry economics carry the project?

Atlanta News First's headline — "Can Delta's green fuel plan keep Georgia forests profitable?" — puts landowner returns at the center. Southeastern timber operates on 20-to-30-year rotations, and prices for sawtimber and pulpwood move with housing starts and export demand. A contracted fuel buyer paying for low-grade fiber could stabilize landowner income during downturns, but only if the offtake price covers gathering, chipping, and hauling across rural road networks.

Forest economists have long flagged a structural challenge in the U.S. South: as paper demand fell, pulpwood markets thinned, pushing more low-grade fiber into pellet export channels. A domestic SAF buyer would create a third bid for that material, tightening supply for existing pellet exporters while raising delivered-cost pressure on the biorefinery.

The economic case hinges on whether mill-conversion capital costs and delivered feedstock expenses stay inside Delta's SAF procurement budget, a figure the carrier does not disclose.

What regulatory pathway applies?

Any SAF produced from this feedstock would need ASTM International qualification for drop-in jet use, a multi-year process that includes specification review, fit-for-purpose testing, and quality-control auditing. Producers also need credit recognition under the Carbon Offsetting and Reduction Scheme for International Aviation and the U.S. Renewable Fuel Standard, both of which require third-party-verified lifecycle emissions accounting.

Lifecycle carbon accounting for forest biomass remains contested in international climate frameworks, and any methodology Delta adopts will shape both eligibility and the price premium the fuel commands.

Where Delta's prior SAF deals point

The carrier's existing SAF portfolio includes long-dated agreements with producers using agricultural and waste feedstocks. Adding a forest-biomass stream would diversify that portfolio and reduce exposure to any single feedstock's price cycle. It would also expose Delta to a different risk profile: wildfire, drought, and timber-market swings that do not affect corn or cooking-oil contracts.

What to watch

Delta has not announced facility partners, capacity, or financial terms. The plan's credibility will rest on three checkpoints:

• A binding offtake price that satisfies landowners
• An ASTM-certified fuel pathway
• A delivered-cost figure that fits within the carrier's SAF budget
