Sustainable Jet Fuel from Lignin
A new process developed by scientists at Washington State University converts lignin, a waste product from trees, into a sustainable jet fuel. This innovation aims to reduce the environmental impact of aviation, which is responsible for approximately 2.5% of global CO2 emissions. By replacing fossil fuel-derived aromatics in traditional jet fuel with lignin-based compounds, the new fuel not only decreases waste but also leads to fewer contrails, which are known to trap heat in the atmosphere. Furthermore, this method is not only more affordable but also viable for commercial-scale production, allowing for easier integration into existing aircraft engines.
