As the importance of sustainable energy production increases, so too does the global commitment to using fuels from renewable biological sources. Biodiesel is one such renewable fuel. Consisting of fatty acids of methyl esters (FAME), it is produced from plant crops by transesterification – a reaction in which natural triglycerides are cleaved and reacted with methanol, producing glycerol and FAME. Rapeseed, soy, sunflower, palm and jatropha are just part of the range of feedstocks used globally in the production of biodiesel.
