SAN FRANCISCO (CBS SF) — Singapore Airlines officials announced Monday that bio-fuel produced from used cooking oil will help power its Airbus A350-900 on the nearly 17-hour flight between Singapore’s Changi airport and San Francisco International.

Airline officials said they would operate a series of 12 flights over a three-month period powered by a blend of sustainable biofuel and conventional jet fuel.

Over the three-month period, the jets will be powered by a combination of HEFA (Hydro-processed Esters and Fatty Acids), a sustainable biofuel produced from used cooking oils, and conventional jet fuel.
