Sinopec Zhenhai Refinery of China Petroleum & Chemical Corporation has obtained a bio-jet fuel airworthiness certificate issued by the Civil Aviation Administration of China on 19 September. The first batch of bio-jet fuel will be shipped to the Airbus (China) Tianjin plant this month. The fuel, derived from used cooking oil, will then be used for flights across China. This will mark the first time that large-scale produced bio-jet fuel will serve the aviation industry in China. The airworthiness certificate means that Sinopec can sell the bio-jet fuel produced at Sinopec Zhenhai Refinery to aviation operators nationwide. The refinery, in the Zhenhai District of Ningbo, Zhejiang province, has an annual designed processing capacity of 100,000 tonnes and adopts Sinopec's bio-jet fuel production technology SRJET to produce the fuel. The plant's first batch in June produced around 600 tonnes of bio-jet fuel. The refinery has already obtained Asia's first global RSB sustainable aviation fuel certification issued by Scientific Certification Systems, a key pass for China's bio-jet fuel to enter the international market. Compared to traditional petroleum-based aviation kerosene, bio-jet fuel can reduce carbon emissions by up to 50% throughout the entire lifecycle.
