INTRODUCTION Due to increasing environmental awareness, Biodiesel is gaining recognition in the United States as a renewable fuel which may be used as an alternative to diesel fuel without anymodifications to the engine. Biodiesel fuels can be produced from ethanol and vegetable oil, both agriculturally derived products. As such, they provide several advantages: they are renewable, they are safer, they are biodegradable, they contain little or no sulfur and they reduce engine exhaust smoke. Currently, the cost of this fuel is a primary factor that limits its use. One way to reduce thecost of Biodiesel is to use a less expensive form of vegetable oil such as waste oil from a potato processing plant. Idaho produces approximately 120 million cwt of potatoes from over 152,000 ha annually. Nearly 60 percent of these are processed., the vast majority being made into French tied potatoes. These operations use mainly hydrogenated soybean oil, some beef tallow and canola It is...
