Can the other white meat's manure make black gold?
They say you can't turn a sow's ear into a silk purse, but University of Illinois researchers are working some interesting magic at the other end of the animal.
"We are the first to actually do this," professor Yuanhui Zhang says proudly of his team's ability to turn swine manure into crude oil. He's a bio-environmental engineer at the University of Illinois Urbana-Champaign who has led the 10-year research project that recently announced a breakthrough in porcine petroleum.
