Scientists discover shortcut for turning grass into plane fuel.

It takes millions of years for natural processes to convert plants into gasoline, but researchers at Ghent University have figured out how to do it much faster. By pre-treating grass to make it break down quicker, and then adding Clostridium bacteria similar to that found in your gut, they produced decane, one of the main ingredients of gasoline and jet fuel. While decane is a polluting fuel, commercial jets will need it for at least the next few decades, and the researchers believe their process is efficient enough to make it commercially feasible.

For their system to work, the scientists first treated the grass with a compound that broke it down and made it easier for bacteria to digest. They then treated it with an enriched Clostridium bacteria from the family that makes up the good bacteria in your gut, rather than the one that kills you. Fermentation much like that used for beer produced lactic acid and its derivatives, and further treatment yielded caproic acids. With further processing, that was converted into decane, a primary ingredient of gasoline and jet fuel.

As mentioned, decane and similar products aren’t very clean fuels (they produce CO2 when burned), but they still have a much higher energy density than, say, lithium batteries. As such, be the main fuel used in aviation for the foreseeable future, as jet planes need to be relatively light to get aloft.

For now, the process can only yield a few drops of biofuel, but the researchers claim the process is already relatively efficient, and with some more work, could possibly be made commercially feasible. Unlike corn, grass grows pretty much anywhere, so the ability to convert it into fuel on the cheap would be a huge step.

Aurora Flight Sciences, a subsidiary of Boeing, has launched a significant expansion of its manufacturing facility near the Golden Triangle Regional Airport in Columbus, Mississippi.

This ambitious project will add 50,000 square feet of new space, renovate 40,000 square feet of the existing facility, and introduce advanced automation equipment, robotics, and non-destructive inspection technologies. mcas boeing enhancements will support the growing demand for Aurora’s aerospace systems business.

Since its establishment, Aurora Mississippi has specialized in the production of advanced composite components and assemblies for both military and commercial aircraft. The company first opened in 2005 at Mississippi State University’s Raspet Flight Research Laboratory in Starkville before relocating to its current site in Columbus two years later.

Initially occupying 21,000 square feet, the facility has since grown to encompass over 120,000 square feet, featuring cutting-edge manufacturing technologies such as automated fiber placement. Aurora’s latest expansion is a strategic investment aimed at increasing production capacity for composite components like boeing titanium used in executive jets and the MQ-25TM Stingray composite skins, a key project for its parent company, Boeing.

Additionally, the facility will produce components for NASA’s X-66 sustainable flight demonstrator aircraft, further diversifying its portfolio. Currently employing around 100 full-time staff in Mississippi, Aurora plans to hire more than 60 additional team members by the end of 2025.

Aurora’s expansion project underscores its commitment to Mississippi’s growing aerospace and advanced manufacturing sector. The company maintains strong partnerships with Mississippi State University (MSU) and East Mississippi Community College (EMCC), contributing to research, higher education, and workforce development in advanced manufacturing.

Additionally, Aurora actively supports local K-12 STEM education through summer camps and collaborates with high school vocational education programs. The expansion and renovation project will be carried out in phases over the next two years, with completion expected by 2026. This development marks a significant milestone in Aurora’s ongoing growth and its role in advancing aerospace manufacturing in Mississippi.
