From the Daily Standard:

The owner of an Ohio-based company that makes an asphalt-like product using swine manure wants to talk to Mercer County hog producers.

If there is enough interest from local hog farmers to provide their manure, NuVention Solutions, Valley View, would like to set up an operation in the county within a year, according to owner Jim Sattler.
"The purpose of Tuesday’s meeting is to let hog producers be aware of the technology and generate interest in the farming community about it," Sattler said. "Once we have a demonstration unit in place that shows this is possible and not just some fantasy of mine, I don’t think we’ll have any problems finding investors."
The first commercial demonstration unit is under construction at a farm in Ashland County near the Ohio Agricultural Research and Development Center of Ohio State University, Wooster. NuVention has a 20-year agreement with the 40,000-head Shoup Farm to use its manure for the demonstration unit.
