NASHVILLE (AP) — Tennessee State University's cooperative extension program is touring the state with its Mobile Biodiesel Education Demonstration trailer.

The university says it will make stops across Tennessee from Monday through March 26 in an effort to provide an up-close look at the biodiesel production process.

Jason de Koff, assistant professor of Agronomy and Soil Sciences, says the production of biodiesel fuel from vegetable oil is a viable process that can replace traditional fuel used in existing diesel engines.

The trailer is scheduled to make stops in Somerville, Sweetwater, Winchester and Dyersburg.
