Boeing and COMAC are sponsoring the China-US Aviation Biofuel Pilot Project, using technology developed by Hangzhou Energy & Engineering Technology Co Ltd to clean contaminants from waste oils and convert it into jet fuel at a rate of 650 litres (160 gallons) per day, a statement of Boeing said.
The two companies estimate that 1.8 billion litres of biofuel could be made annually from used cooking oil in China.
"Strong and continuing teamwork between Boeing and COMAC is helping our industry make progress on environmental challenges that no single company or country can solve alone," said Ian Thomas, president of Boeing China.
