Additive boosts biofuel use

Sydney, Oct 27 (IANS) An additive developed by Flinders University could significantly boost biofuel use following its commercialisation.The additive lowers the temperature at which tallow-based biodiesel solidifies - a problem which causes fuel flow difficulties and has constrained the take-up of biofuels made from the waste products of abattoirs.

Leader of Flinders Materials and Bio-energy Group, Stephen Clarke, said there “is a huge potential market for tallow-based biofuels, with the current consumption of petroleum diesel being around 15 billion litres annually in Australia”.

“The additive that Flinders has developed removes one of the major impediments to the use of tallow-based biofuels and this market could expand considerably, perhaps to around one billion litres a year, when our product can be added to biofuel blends,” Clarke said.

Flinders’ industry partner, Meat and Livestock Australia, has secured a provisional patent over the university’s additive which can lower the solidification temperature of tallow-based biodiesel or diesel blends by about five degrees celsius, to around minus six degrees celsius, according to a Flinders release.

The temperature difference will boost the potential to use tallow-based biofuel in colder parts of Europe and elsewhere.
