Missouri project ‘a new level’ in manure biogas production

By Karen Uhlenhuth, Midwest Energy News.

This summer, one of the country's largest producers of biogas from animal manure is expected to begin operations in northwest Missouri.

It's a large-scale example of technology that has been slow to take off in the United States, but new federal policy may be changing that.

In 2013, St. Louis-based Roeslein Alternative Energy reached an agreement with pork giant Smithfield Foods to build and operate a system to capture and purify methane from the manure produced by about two million pigs. Smithfield's confinement barns comprise one of the largest hog-feeding facilities in the country, according to Roeslein.
