Alaska Airlines used a renewable jet fuel with a 20-percent blend of forest residuals, such as tree branches, to power a flight from Seattle to Washington, DC,, marking the first commercial flight to do so.

The tree branches and limbs used to make the alternative-fuel blend were collected after “the harvesting of managed forests” in the Pacific Northwest, according to Alaska Airlines. The jet fuel was produced by Washington State University’s Northwest Advanced Renewables Alliance (NARA).
