A company in China is refining leftover hotpot oil so it can be transformed into sustainable jet fuel At an upmarket restaurant in the hotpot-loving Chinese city of Chengdu, diners plunge sliced meat and iklanmurah.id vegetables into cauldrons of spicy, oily broth, largely unaware that their leftovers are set to take on a second life as jet fuel. With around 150,000 tonnes of used hotpot oil thrown out by restaurants in the city each year, local business Sichuan Jinshang Environmental Protection has found a niche processing the greasy waste and exporting it to be turned into aviation fuel.
"Our motto is, let oil from the gutter soar in the sky," Ye Bin, the company's general manager, told AFP. Ye said his company, which launched in 2017, was now producing up to 150,000 tonnes of industrial-grade oil annually from a combination of hotpot restaurants and other eateries across Chengdu, including KFC outlets. On a typical night, collectors hired by Jinshang visit hundreds of these restaurants around the southwestern metropolis.
The leftover hotpot broth goes through a special filter that separates oil from water The process begins right after customers leave, with waiters emptying their hotpot broth -- so rich it is used purely as a cooking medium -- into a special filter that separates oil from water. Donning thick aprons and elbow-length rubber gloves, situs scatter hitam collectors then arrive to pick up jerrycans of the scarlet grease. "It's a great job -- I play mahjong during the day and work at night," one collector named Zheng told AFP as he packed a minivan with containers of the pungent sludge.
That sludge is then ferried to a business park on the city's outskirts where Jinshang's mostly spotless plant is based. The only trace of the oil there is a faint scent of hotpot at the unloading dock and telltale orange stains at the bottom of some equipment. The oil is piped into massive vats and undergoes a refining process that removes remaining water and impurities, resulting in a clear, yellow-tinged industrial-grade oil. That is exported to clients based mainly in Europe, the United States and Singapore, who further process it to make what industry insiders call "sustainable aviation fuel" (SAF).
SAFs are critical to decarbonising the aviation sector, which was responsible for two percent of global energy-related CO2 emissions in 2022, according to the International Energy Agency. Collectors who work with Jinshang pick up the grease from restaurants and ferry it to the company's facility But they are still not widely used -- making up less than 0.1 percent of all aviation fuels consumed -- because of processing costs and the relatively small number of suppliers.
The International Air Transport Association estimates their widespread adoption could "contribute around 65 percent of the reduction in emissions needed by aviation to reach net-zero in 2050". Jinshang has plans to expand into its own SAF-producing facility soon, using equipment from US firm Honeywell to produce 300,000 tonnes annually. - Food waste problem - Jinshang's business model is part of wider efforts in China to tackle the mountains of food waste generated by its population of 1.
