Vegetable oil fuel States was producing in excess of 11 billion liters (2.9 billion U.S. gallons) of recycled vegetable oil annually, mainly from industrial deep fryers in potato processing plants, snack food factories and fast food restaurants. If all those 11 billion liters could be recycled and used to replace the energy equivalent amount of petroleum (an ideal case), almost 1% of US oil consumption could be offset. Utilizing recycled vegetable oil as a replacement for standard petroleum-derived fuels like gasoline would reduce the price of gasoline by preserving the supply of petroleum. Virgin vegetable oil, also termed pure plant oil or straight
Butter It is rare in Europe as well. Several "spreadable" butters have been developed. These remain softer at colder temperatures and are therefore easier to use directly out of refrigeration. Some methods modify the makeup of the butter's fat through chemical manipulation of the finished product, some manipulate the cattle's feed, and some incorporate vegetable oil into the butter. "Whipped" butter, another product designed to be more spreadable, is aerated by incorporating nitrogen gas—normal air is not used to avoid oxidation and rancidity. All categories of butter are sold in both salted and unsalted forms. Either granular salt or a strong
