Converting plastic waste into jet fuel could support aviation decarbonization, but current approaches are limited by high-pressure requirements and low efficiency. Here the authors present a tandem hydropyrolysis and vapour-phase hydrogenation strategy that uses a Ru/Co-Al oxide catalyst, achieving promising rates and yields at low pressures.
