New method converts plastic waste into aviation fuel cheaply using mild conditions and metal catalysts

Researchers from the Shanghai Advanced Research Institute and Fudan University have developed a catalytic process that turns polyolefin plastics, such as polyethylene and polypropylene, into aviation fuel. These plastics make up over 60% of plastic waste and are normally hard to break down. The method uses hydrogenolysis under mild conditions with metal catalysts to selectively produce hydrocarbon chains in the jet fuel range. This approach could lower the cost of sustainable aviation fuel while addressing plastic waste. However, the article does not provide specific cost numbers, catalyst materials, or energy input data. Without those details, it is hard to assess real-world viability or emissions impact. The process is still at the research stage and would need pilot-scale validation before any commercial deployment.
