The red giant is looking to "go green"

The Chinese government has struggled with so-called "gutter oil".  Formed from used cooking oil -- or sometimes from vat-cooked rotten or discarded animal parts -- the low-quality oil is often resold to unsuspecting customers who then use it to cook customers' food.  Gutter oil is hard to identify, but it does come with some dire health effects like diarrhea and abdominal pain.  Worse, some evidence indicates it can cause cancer in adults and developmental disabilities in children.

A joint research institute founded by China's state-owned Commercial Aircraft Corp. of China (COMAC) and the world's largest aerospace company, The Boeing Comp. (BA), is aiming to provide a legal alternative by refining gutter oil into biofuel that can be used to fuel aircraft.

In August the pair founded the Beijing Aeronautical Science and Technology Research Institute (BASTRI) -- an institute that collaborates with Chinese universities on cutting edge aerospace research.  BASTRI's Aviation Energy Conservation and Emissions Reductions Technology Center will be partnering with a Chinese green energy company -- Hangzhou Energy Engineering & Technology, Comp., Ltd., (HEET) -- on its first major project, the jet biofuel initiative.

Dong Yang Wu, vice president of Boeing Research & Technology - China - commented, "HEET is a strong partner for the Boeing-COMAC technology center's 'gutter oil' research project.  We are excited about opportunities to partner with leading research capabilities in China to accelerate the global push for renewable jet fuels and support commercial aviation's growth while reducing its environmental footprint.

Currently, China uses 29 million tons of cooking oil a year, while also consuming 20 million tons of jet fuel.  With demand for jet fuel on the rise, there's a strong impetus to find affordable ways to convert China's massive stock of waste oil to fuel for aircraft.

Qin Fuguang, president of BASTRI, COMAC, comments, "China is the world's fastest growing aviation market and the biggest consumer of cooking oil. There's great potential for converting the waste cooking oil into sustainable aviation fuel. It's a good opportunity for Boeing, HEET and COMAC to work together and make efforts to protect the environment."

China is not alone in pursuing biofuels for use as jet fuel.  The U.S. military has been testing aircraft biofuels, including algal fuels.  Air New ZealandVirgin Airlines, and Lufthansa have all been testing flights powered by biofuel, as well.  The issue of fuel expenses is a particularly sore issue for the U.S. where rampant obesity causes the U.S. airline industry to have to pay $275M USD more per year than their foreign peers.

It has to do with a combination of factors like octane, viscosity, stoichiometric ratio of the fuel, how corrosive it is, and how cleanly it burns that determines whether or not a piston-based ICE can run on it. Jet engines are more flexible on several of those factors and the combustion temperatures can get much higher and they're much more volumetrically efficient, etc. The army does have motorcycles and the like that can run on any hydrocarbon in a certain molecular weight range from gas, diesel, LPG, CNG, butane, kerosene, etc. It's not that piston engines can't do it, it's just easier with better results with jet engines.
