<p>Decarbonising aviation sector is imperative for achieving net-zero targets. Biomass-derived sustainable aviation fuel (SAF) represents a carbon-neutral alternative for fossil-based fuels and enables substantial emissions mitigation. This review discusses the advancement of the currently employed Fischer-Tropsch Synthetic Paraffinic Kerosene (FT-SPK) pathway for SAF production through incorporating catalyst-assisted co-gasification. It outperforms conventional gasification by leveraging catalyst and co-feed approaches, reducing energy input while generating high-quality syngas. This comprehensive evaluation examines the interaction among biomass, co-feed, and catalysts, highlighting their pivotal role in enhancing the H₂/CO ratio and FT-SPK selectivity. The role of different catalysts, such as mineral, transition metal, alkali, and alkaline earth metals, carbon-based, and waste-derived catalysts in producing the desired syngas quality (H₂/CO: ~2) are critically reviewed. FT synthesis has been elaborated by emphasizing the catalysts and process mechanism with respect to FT-SPK production. Furthermore, we have explored the economic and environmental challenges associated with FT-SPK production and proposed strategies that align with the circular economy principles, advocating for a transition toward sustainable solutions in aviation fuel production. Eventually, it supports the Sustainable Development Goals (SDG) 7 guidelines on a reliable and energy-efficient solution that could reflect in the aviation sector.</p> Graphical Abstract <p></p>
