Iowa DNR still eager to control hog odors
January 17, 2008

The State of Iowa is in the midst of some tight budgetary days, but among the priorities the DNR still intends to see carried out is a project to manage odors at livestock confinements across the state. One of the best ways to do so is by installing geomembrane covers over hog-waste lagoons, which not only capture the odor-causing gases but turn them into a potential source of profit, since most of the gasses being released can be recovered for use as natural gas. The payback period can be surprisingly short -- just a couple of years, in most cases.
