Clean Energy Chemical Breakthrough Turns Plastic Waste Into Potent Jet Fuel
A new path to cleaning up the world’s plastic waste might start on the runway. Researchers from Nanjing Forestry University and Tsinghua University have developed a tandem reactor system capable of converting discarded plastics directly into aviation-grade fuel, potentially providing a double solution for the global waste crisis and the aviation industry’s struggle to decarbonize.
The process addresses the selectivity problem that has long plagued plastic-to-fuel research. Currently, chemical recycling methods often produce a messy cocktail of chemical byproducts, making it difficult to refine them into high-performance jet fuel. By employing a specialized two-stage reactor, the Chinese research team managed to exert precise control over the molecular transformation.
In the first stage, the plastic waste is fed into a reactor operating at 460°C (860° F), where it is broken down into smaller, intermediate molecular compounds. The latter is then passed into a second reactor operating at 160°C (320° F). Here,...
