Tomorrow morning, Wednesday, July 18th between 8 and noon, Kum & Go gas stations in 17 locations in Iowa will hold “Biodiesel Appreciation Day”… offering B2 biodiesel for 10 cents a gallon off the regular price.

This article from EarthTimes.org says it is the biggest biodiesel promotion in the Upper Midwest and has gained the praise of politicians, environmentalists, and some folks concerned about your breathing: the American Lung Association:

“While ethanol makes a lot of headlines, especially here in Iowa, biodiesel has become the sleeping giant of biofuels,” said Jessica Zopf, environmental health coordinator for the American Lung Association of Iowa. “Iowa produces 225 million gallons of cleaner-burning biodiesel a year, which can significantly reduce harmful tailpipe emissions when used in higher concentrations. Buying a two percent blend biodiesel may be a small step, but it is a vital beginning on a path toward cleaner air, greener fuels and less dependence on petroleum.”
