Sustainable aviation fuel (SAF) is a biofuel that can reduce carbon emissions from air transportation.

 Sustainable aviation fuel (SAF) is a biofuel that can reduce carbon emissions from air transportation. It's made from non-petroleum feedstocks like waste oil, non-food crops, and algae. SAF can be blended with traditional jet fuel at levels up to 50%. 

How is SAF made?

Waste oil and fats: Used cooking oil can be collected and transformed into fuel. 

Algae: These microscopic plants can be grown in polluted or salt water, deserts, and other inhospitable places. 

Non-food crops: Crops that don't compete with food crops or water supplies can be used to produce SAF. 

Carbon capture: Carbon can be captured directly from the air and used to produce SAF. 

Benefits of SAF

SAF can reduce carbon emissions by up to 80%. 

SAF is a drop-in solution that can be blended into existing fuel infrastructure at airports. 

SAF is fully compatible with modern aircraft. 

SAF can be handled in the same way as traditional jet fuel. 

Challenges

SAF is currently more costly than traditional fossil jet fuel. 

Biofuel production, processing, and transport emit greenhouse gases, reducing the emissi

ons savings.
