Jet fuel

​Commonly used to make a wide variety of items, low-density polyethylene can be recycled into new plastic, but there's much more waste than recycling facilities can currently handle. With that in mind, scientists have now devised a method of converting the material into something else – jet fuel.

Using jet propellent and a combination of enzymes as catalysts, researchers at the University of Utah have produced a prototype fuel cell that runs at room temperature and without the need to ignite the fuel.
