UI researcher makes crude oil from pig manure

ILLINOIS - 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.

That neat trick may sound crude.

But it also sounds good to a pork industry swamped with oceans of swine manure, and it sounds like the national anthem to those looking to reduce America's dependence on foreign oil.

A typical pig produces about 6 gallons of waste a day.

For a hog farmer like Pat Dumoulin of Hampshire, who has about 1,200 sows, that's enough stinky and potentially hazardous fumes that he has a pair of 500,000-gallon tanks to properly store the stuff.

Like most farmers, much of the manure from Dumoulin's hogs winds up as fertilizer.

"Most of the farmers in our area are open to taking the hog manure," says Dumoulin, whose farm has been in his family for more than 50 years. "Sometimes it's done for no cost, sometimes they pay us a fee to spread it on their fields."

Either way, scientists have agreed for years that the chemical and capital potential of pig manure, like almost all organic waste, could have other uses.
