Scientists at Washington State University have made a key breakthrough in creating jet fuel from plant waste , a major step toward using renewable energy in aviation . Using agricultural waste such as lignin, the team developed a continuous process to convert these byproducts into an efficient biofuel.
Jet fuel from lignin
The process, known as “simultaneous depolymerization and hydrodeoxygenation,” allows lignin to be broken down and oxygen removed in a single step , transforming this plant polymer into fuel. Lignin comes from materials such as corn stover and other crop residues, making this technology sustainable and environmentally friendly.
This biofuel has the potential to replace fossil-derived compounds, known as aromatics, which are still needed in commercial aviation. The advantage of this new fuel is that it could reduce condensation trails and improve efficiency in jet engines, making it a promising alternative.
Significant environmental impact
The global demand for aviation fuel is constantly growing, and this new development could play an essential role in reducing the industry’s carbon footprint . With this type of innovation, it is expected that aircraft will be able to use 100% renewable fuels in the future , without the need to modify engines or infrastructure.
The research team is now looking to refine the process to increase efficiency and reduce costs, a crucial step toward its large-scale commercialization. In addition, this technology has been backed by major institutions such as the U.S. Department of Energy.
Sustainable fuel derived from lignin could be the complement that the industry needs to achieve cleaner and more sustainable air transport .
