"The muddy gutter oil, like soy sauce, transforms into clear and transparent biodiesel and sustainable aviation fuel, doubling its value." Li Jianping, Chief Engineer of Henan Junheng Industrial Group Biotechnology Co., Ltd. (hereinafter referred to as "Junheng Biotechnology"), introduced that compared to traditional petroleum based aviation fuels, sustainable aviation fuel (SAF) reduces carbon emissions by nearly 80%. On January 20th, Junheng Biotech's SAF obtained airworthiness approval from the Civil Aviation Administration of China, marking the first private petrochemical enterprise in China to officially obtain airworthiness approval and put it into commercial use. Xia Zuxi, Director of the China Civil Aviation Aviation Fuel Airworthiness Certification Center, introduced that SAF is a new type of aviation fuel that mixes green aviation fuel made from biological manufacturing with traditional fuel in a certain proportion. It can achieve a reduction of over 80% in net carbon dioxide emissions throughout the entire life cycle and is a feasible alternative to green aviation energy. The return of waste oil (gutter oil) from SAF crab meals to the dining table by private enterprises can harm human health and affect food safety. However, SAF prepared from food waste oil is a high-performance carbon neutral fuel. Zhang Zhenhui, Executive Director of Junheng Biotechnology, introduced that the company's independently developed green and low-carbon biofuel technology, which has lasted for 5 years and ended its fruitful results, has started a new chapter in green environmental protection by using waste oil such as gutter oil and waste oil as production materials, transforming waste oil from "toxic" to "treasure", from harming society to serving society and benefiting humanity. In early January, Junheng Biotech's SAF was still conducting performance and functional tests on the auxiliary power unit test bench, and all test results met the standards, equivalent to jet fuel No. 3. This is also the first 100% sustainable aviation fuel engine test in China. Zhu Liangcai, Mayor of Puyang City, Henan Province, introduced that Junheng Biotechnology's SAF has been approved by the Civil Aviation Administration for airworthiness and has obtained the qualification to enter the civil aviation market. This is a fruitful achievement of Junheng Biotechnology's technological innovation and a successful practice of Puyang's industrial transformation and upgrading. Puyang is the Central Plains Petrochemical City. Currently, Puyang City has planned and constructed a new chemical base covering an area of 65 square kilometers, which is the only new chemical base approved by the provincial government in Henan Province. It is the region with the most complete petrochemical industry system in Henan Province. As a rapidly growing private enterprise in Puyang, Junheng Biotechnology is the world's first to develop high acid and water resistant catalysts and waste animal and vegetable oil hydrogenation treatment processes. Its related products are exported to the European Union, and its operating revenue exceeded 2.2 billion yuan in 2023. Taking a substantial step towards "green fuel" With the rapid development of the civil aviation industry, the demand for aviation fuel has increased rigidly, and the large amount of greenhouse gas emissions generated by its combustion have become a constraint on decarbonization in the civil aviation industry. "Developing SAF to promote green and low-carbon transformation has become a new track of competition in the global aviation industry," said the relevant person in charge of the Airworthiness Certification Department of the Civil Aviation Administration of China. The International Civil Aviation Organization (ICAO) has proposed long-term vision goals for 2050 and launched an international aviation carbon offsetting and emission reduction plan. Under this mechanism, Chinese civil aviation enterprises will pay about 20% of their annual net profit as aviation carbon emissions expenses. In 2023, the European Parliament approved the European Clean Fuel Act aviation regulations, which require at least 2% of aircraft taking off and landing at EU airports to use "green fuel" by 2025, and by 2050
