Hello Calldare2000,
What is biofuel?
Biofuel is a generic term for fuels that can be produced from or are made up of a renewable material of plant or animal origin. Often they are substitutes or partial substitutes for fossil or mineral fuels. Biofuels used in transport are typically bioethanol which is used as a petrol substitute and biodiesel which is used as a diesel substitute. These are the biofuels that are most likely to be used in New Zealand in the medium term. Biofuels have the major advantage of not contributing to overall greenhouse gas emissions.

What is biodiesel?
Biodiesel can be produced from any vegetable oil or animal fat and used as a substitute or partial substitute for mineral diesel. To produce biodiesel, these fats or oils are chemically converted to esters that have properties similar to mineral diesel. Biodiesel is often blended with mineral diesel and is available for retail sale in New Zealand in blends of up to 5 percent. Some commercial customers buying fuel in bulk may use higher blends of biodiesel. Blends of up to 5 percent in mineral diesel are suitable for use in diesel engines without modification. Higher blends may be used in dedicated fleets.

What is bioethanol?
Bioethanol is an alcohol made from sugar, starch and products containing sugars and starches, through a process of fermentation and distilling, and used as a substitute or partial substitute for petrol. Bioethanol has properties that are similar to petrol so it is often blended with petrol. In New Zealand bioethanol-blended petrol is available in blends of up to 10 percent, although it has also been introduced at a lower level blend i.e 3 to 5 percent in some petrol. Higher blends may be used in dedicated fleets.
Nice weekend!
The process of making biodiesel occurs as follows:
A) The triglycerides (oil from algae), methanol, and catalyst are placed in a controlled reaction chamber to undergo transesterification.
B) The initial product is placed in a separator to remove the glycerine by-product.
C) The excess methanol is recovered from the methyl esters through evaporation.
D) The final biodiesel is rinsed with water and pH neutralized (Xu et al., 2006).
