The International Civil Aviation Organization launched a carbon offsetting and reduction scheme in 2016 that encourages the use of sustainable fuels in addition to technical and operational improvements. The European Union is also tightening its rules, introducing new requirements that its planes and airports blend in 5% sustainable aviation fuels by 2030, gradually rising to 85% in 2050. That leaves a lot of room for growth, especially as governments and industry regulators tighten rules to meet emissions targets that are key to averting catastrophic global warming. So far, less than 3 million tons of it ends up in the supply chain for biodiesel, a major type of biofuel that’s surged in price amid rising European demand, according to a report by state-owned People’s Daily last year. Originally set up during China’s food safety crisis to stop contaminated “gutter oil” from being filtered and sold back to food vendors, Jinshang began to export the leftover fat for industrial use in 2016, when demand for biofuels from international refiners first took off.Ĭhina consumes more edible oil than any other country - more than 41 million tons a year. Its end product is a biofuel precursor usually called industrial mixed oil, which is then packed on ships that sail east along the Yangtze River to the port of Shanghai, from where it’s exported to Neste Oyj, the world’s largest producer of sustainable aviation fuel, and to global energy giants including BP Plc and Eni SpA, to be further refined into biodiesel or jet fuel. The Chengdu-based company collects used oil, mostly from hot pot restaurants in the Sichuan capital of 16 million, and removes impurities such as sodium and metal particles. “Our mission is to make gutter oil fly to the sky,” said Zhong Guojun, vice president of Sichuan Jinshang Environmental Technology, which is behind the project. And China, with its large population and love for super-greasy hot pots, is already the largest exporter. Waste oil from kitchens is emerging as a major source of sustainable jet fuel because it doesn’t displace food production or encourage deforestation to make way for crops. and Delta Air Lines Inc., have pledged to replace about 10% of their jet fuel with a sustainable alternative by 2030, and more than 50 have begun to experiment with it, but cleaner substitutes are still being developed. Several major airlines including British Airways, Cathay Pacific Airways Ltd. Responsible for around 2% of the world’s total emissions of planet-warming gases, the aviation industry is under pressure to find greener ways to power its jet engines. So in 2016, a startup began exporting some of that leftover restaurant grease to Europe and Singapore, where it gets recycled into fuel pure enough to fly airplanes. It’s a rich delicacy, one that produces about 12,000 tons of waste oil each month in the Chinese city of Chengdu alone. Diners first immerse slivers of meat in a spicy soup rich in molten animal tallow, then dip each morsel in a plate of vegetable oil, before finally devouring it. (Bloomberg) - There’s a ritual involved in creating the perfect Sichuan hot pot and it involves fat - lots of it.
