Seattle-based Alaska Airlines has made the first commercial flight utilising alternate jet fuel made from forest residuals— the wood that remains after a forest harvest.
The November 14 flight with a Boeing 737-800 - fueled by 1,080 gallons of biofuel - travelled from Seattle to Washington Reagan National Airport carrying 163 passengers.
The flight was fueled with a 20% blend of sustainable aviation biofuel, which is chemically indistinguishable from regular jet A fuel.
The flight, the first commercial passenger flight of its kind, continues to advance viable alternatives to conventional fossil fuels for aviation, Alaska Airlines said.
“Cellulose, the main component of wood, is the most abundant material in nature and has long been a subject of investigation for producing sustainable biofuels,” the U.S. Department of Agriculture said.
Alaska Airlines flew two flights in June using a blend of biofuel produced from non-edible, sustainable corn.
