The C919 aircraft completed maiden test flight with sustainable aviation fuel (SAF) produced by Sinopec earlier this month.

China’s homegrown large passenger aircraft, the C919 made a soft landing on the runway of Dongying Airport in Shandong Province, marking the first time for the domestic commercial aircraft to be fueled with SAF.

On the same day, another homegrown aircraft ARJ21 fueled with Sinopec SAF, completed its test flight at Shanghai Pudong Airport.

Produced from Used Cooking Oil (UCO), Sinopec SAF is able to cut carbon emissions by over 50% throughout the life cycle, compared with conventional aviation fuel.
