Tiny Flower Turns Pig Poop into Fuel

Duckweed, they discovered, has an appetite for animal waste, quickly converting it to leafy starch that can then be converted into ethanol. The current source for most U.S. ethanol is industrial-scale corn farming, which requires large amounts of toxic pesticides and dead zone-feeding, fuel-intensive fertilizers. When the costs are added up, corn-based ethanol may prove little cleaner than gasoline.

Duckweed could help solve both problems at once.
