Food waste oil becomes airplane fuel

 

Food waste oil becomes airplane fuel: At an upscale restaurant in Chengdu, China’s hot pot capital, diners plunged slices of meat and vegetables into a large pot of spicy, greasy broth, mostly unaware that the hot pot soup base was being prepared for a new life as aviation fuel. Second spring.

Restaurants in Chengdu throw away about 150,000 tons of used hot pot oil every year, and local company Sichuan Jinshang Environmental Protection Company discovered this business opportunity and processed the greasy waste into aviation fuel for export.

Ye Bin, the company’s general manager, told AFP that his company’s motto is, “Let gutter oil soar into the sky.”

150,000 tons of industrial-grade oil are extracted from gutter oil every year
Ye Bin said his company, founded in 2017, now produces up to 150,000 tons of industrial-grade oil annually from hot pot restaurants and other restaurants in Chengdu, including KFC fast food restaurants.

On a typical night, collectors hired by Jinshang visit hundreds of restaurants in the southwestern metropolis. As soon as customers leave, waiters pour their hot pot soup into a special filter that separates oil and water.

The collectors then put on thick aprons and elbow-length rubber gloves to collect jars of the scarlet grease.

The grease was then transported to a business park on the outskirts of the city, where Jinshang’s factory is located, and the premises are largely spotless. The only traces of oil in the factory were the faint smell of a hot pot on the loading dock and the obvious orange stains on the bottom of some equipment.

The grease is piped into vats, where it undergoes a refining process that removes remaining moisture and impurities, eventually becoming a clear, yellow, industrial-grade oil.

Export to Europe, America, and Singapore to refine aviation fuel
The oil is exported to customers mainly in Europe, the United States, and Singapore, who further process it into what industry insiders call “sustainable aviation fuel” (SAF).

According to the International Energy Agency, the aviation industry will emit 2% of total global energy-related emissions in 2022.

However, due to processing costs and a relatively small number of suppliers, recycled aircraft fuel is still not widely used, accounting for less than 0.1% of all aviation fuels.

Recycled fuel is still not widely available
The International Air Transport Association estimates that the widespread use of recycled aviation fuel can contribute about 65% of the emissions reductions required for the aviation industry to achieve net-zero emissions in 2050.

Jinshang plans to expand its SAF production facilities shortly, using equipment from the American Honeywell Company, and the annual output will reach 300,000 tons. The company’s business model is part of China’s broader efforts to tackle the vast amounts of food waste generated by its 1.4 billion people.

According to a 2021 study in Nature, about 350 million tons of agricultural products are discarded by restaurants, supermarkets, or consumers in China every year.

The EPA says that in landfills, rotting food waste emits atmosphere-warming methane gas faster than most other materials.

China continues to tackle the food waste problem
This is a huge headache for Chinese cities and a major threat to global climate goals. The Chinese government has vowed to tackle the problem in a recent methane emissions plan that calls for the construction of innovative food waste treatment projects across the country in the next few years.

In Shanghai, city waste facilities have turned to the humble black soldier fly to turn tons of food waste into fertilizer and animal feed each year.

According to Wu Yuefeng, deputy director of the plant, 500 million maggots are living in a sealed cave at the Laogang garbage treatment plant, which eats up to 2,500 tons of food waste every day.

The maggots are destroyed at their fullest, with the grubs expelling a black, earthy substance that is reused as livestock feed.
