Waste vegetable oil that has been filtered. Vegetable oil can be used as an alternative fuel in diesel engines and in heating oil burners. When vegetable oil is used directly as a fuel, in either modified or unmodified equipment, it is referred to as straight vegetable oil (SVO) or pure plant oil (PPO).
The following table shows the vegetable oil yields of common energy crops associated with biodiesel production. Included is growing zone data, relevant to farmers and agricultural scientists. This is unrelated to ethanol production, which relies on starch, sugar and cellulose content instead of oil yields.
The German government has a Biofuels Roadmap in which they expect to reach 10% biofuels by 2010 with the diesel 10% coming from fuel made from vegetable oil. [18] From 2005 to 2007 a number of types of vegetable oil have doubled in price. The rise in vegetable oil prices is largely attributed to biofuel demand. [19]
Base-catalyzed transesterification reacts lipids (fats and oils) with alcohol (typically methanol or ethanol) to produce biodiesel and an impure coproduct, glycerol. [6] If the feedstock oil is used or has a high acid content, acid-catalyzed esterification can be used to react fatty acids with alcohol to produce biodiesel.
The IEA estimates that biodiesel production used 17% of global vegetable oil supplies in 2021. [ 26 ] Oils and fats reacted with 10 pounds of a short-chain alcohol (usually methanol) in the presence of a catalyst (usually sodium hydroxide [NaOH] can be hydrogenated to give a diesel substitute.

Bio Energy Resources Ltd. of Malawi announced in May 2011 that it would construct a USD 18 million plant [25] with an annual production capacity of 20 million liters [26] which were to process the seeds of Jatropha Curcas into Straight Vegetable Oils, which were to be blended with diesel to make bio-fuel and with paraffin to make bio-paraffin ...
Total world production of vegetable oil for all purposes in 2005–06 was about 110 million tonnes, with about 34 million tonnes each of palm oil and soybean oil. [86] As of 2018, Indonesia is the world's top supplier of palmoil-based biofuel with annual production of 3.5 million tons, [ 87 ] [ 88 ] and expected to export about 1 million tonnes ...
Diesel for land and sea transport will be a blend of 5% processed palm oil and 95% petroleum diesel. This ‘B5’ would be made available throughout the country. Objective 2: Biofuel for Industry. Supply B5 diesel to the industrial sector, to be used as fuel in industrial boilers, construction machinery, and diesel-powered generators.
