Duckweed Turns Pig Poop into Biofuel
Researchers from North Carolina State University have shown that Duckweed, a tiny aquatic plant much loved by Ducks can thrive in the effluent waste water produced by large feedlots, such as hog farming operations and potentially in urban sewage water as well. This hardworking little plant not only cleans the waste water of the excess nutrients, but in the process it produces large quantities of valuable starchy biomass. Biomas that can be harvested and used to produce ethonol in the same types of facilities that are currently being used to make ethanol from corn starch.
