WHITAKERS, N.C. — After years of struggling with the dirty disposal
problem of sludge from hog waste lagoons, researchers have come up with
a possible green solution: poplar trees that suck up the waste like soda
straws.
If the procedure works well enough to be approved by state water quality
officials, it could more than cut in half the cost of closing a waste
lagoon, currently done with bulldozers and dump trunks.
"It is a simple method," said Frank Humenik, coordinator of the animal
waste management program at North Carolina State University.
