Boeing and Commercial Aircraft Corp of China (Comac) launched a joint pilot project to turn used cooking oil into jet fuel.
The plant in the Eastern Chinese city of Hangzhou is expected to convert just under 240,000 liters a year of used cooking oil into fuel, according to Boeing, Reuters said.
The two aircraft makers plan to test the viability of producing biofuel using the cheap and widely available form of cooking waste, referred to in China as "gutter oil".
The companies estimate that 1.8 billion liters of fuel could be produced in China a year using that oil.
