An ARJ21 regional aircraft and C919 passenger aircraft completed their first demonstration flights with Sustainable Aviation Fuel (SAF) in Shanghai and Dongying, respectively. The demonstration flights showed a sound flight performance.

SAF is a liquid aviation fuel alternative to traditional jet fuel. Made from renewable materials, it can reduce carbon emissions by up to 80 percent over the fuel’s life cycle compared to conventional jet fuel. So far, a number of Chinese airlines have conducted commercial test flights using China-made SAF, with a dozen domestic enterprises and institutes working on the research, development and production of SAF.

Making full use of green resources, the SAF used in the demonstration flights was made from waste oil from meals. The oil is recycled and processed in China’s first bio-aviation fuel industrial plant built by Sinopec, before it is transformed into bio-jet fuel. The SAF  was granted airworthiness approval by the Civil Aviation Administration of China in February 2024.
