Aviation fuel blending combines conventional petroleum-based jet fuel (ATF) with Sustainable Aviation Fuel (SAF)—derived from renewables like waste oils, fats, and alcohols—to reduce carbon emissions. SAF is blended up to 50% under ASTM D7566 standards, acting as a "drop-in" fuel compatible with existing aircraft engines. Recent regulations in India are allowing ethanol-to-jet (ATJ) pathways, while global mandates, such as in the UK and Japan, are increasing, targeting 5% SAF by 2030.

Key Aspects of Aviation Fuel Blending: SAF Composition: - SAF can be produced from waste fats/oils, municipal solid waste, and alcohol-to-jet (ATJ) conversion. Blending Ratios:- Certified to be blended up to 50% with conventional jet fuel, ensuring necessary aromatic levels for safety. Benefits: - Reduces lifecycle carbon emissions by up to 80% compared to conventional fuel. Key Trends (2026): - India now allows synthetic components in ATF to lower import dependence and align with internationa...
