Triangle Biofuels customer Diamond Surface Inc. (http://www.diamondsurfaceinc.com/) has been contracted by the State of NC to do road work on a stretch of I-95 near Rocky Mount.  Their fuel of choice was Biodiesel. 

Diamond Surface operates three grinders on the project, each running B20 in its diesel engine as it grinds away the road surface.  The workers' initial response was to comment how much cleaner it burned when running on biodiesel, "there's no black smoke like before".

Diamond Surface is based out of Maple Grove, MN.
