How does SVO compare with biodiesel?
SVO and Biodiesel are quite different fuels however they are often confused as biodiesel is produced from SVO. Biodiesel is made when vegetable oil molecules are split four ways by a chemical reaction called transesterification. Since biodiesel is produced from SVO it also has low net CO2 emissions. However, since the transesterification reaction requires energy and some of the chemicals needed to carry out the reaction generally come from fossil fuels this means that biodiesel has higher net CO2 emissions than SVO. In short, SVO is the better of the two fuels for reducing CO2 emissions.
