|Biodiesel is a generic name for a diesel replacement fuel that is manufactured from either vegetable oils, animal fats and or recycled cooking oils. Biodiesel is manufactured from naturally occurring fats from plants and animals.|
The manufacturing process converts these oils and fats into chemicals called fatty acid methyl esters (FAME) or more commonly biodiesel. Glycerine is a co-product of the biodiesel manufacturing process.
Replacing petroleum derived diesel fuel with biodiesel offers these advantages:
It can be
used in most diesel equipment with no modifications or, in some instances,
only minor modifications.
Biodiesel can be used as a blend in any proportion with petroleum diesel.
In a blend the number following the “B” indicates the percentage of biodiesel, for example B20 is 20% biodiesel blended with petroleum diesel, B5 is 5% biodiesel blended with petroleum diesel.
Starting in Europe, the production and use of biodiesel has developed and become well established in many parts of the world. Annual consumption in Europe is about 3 billion litres.
Initial production in Europe was from rapeseed oil (canola), whereas manufacturers in the US used soybean oil. Further developments have seen the use of animal fats and used cooking oils. Whilst in Asia, palm oil is the principal feedstock.
In 2001, the Australian Government set an objective that biofuels would
contribute at least 350 million litres to the total fuel supply by 2010.
It is anticipated that biodiesel will be an important component of this
Extending Fuel Supply
Together with measures such as improving vehicle fuel efficiency, ethanol and biodiesel as additives to gasoline and diesel can help offset some of our demand for petroleum and therefore extend the timeframe for new alternate energy sources to be developed. Importantly this is achieved whilst also reducing emissions and greenhouse gas (GHG's).
The Australian transport sector is very heavily dependent on oil and more so than other developed nations.
Transport fuel accounts for 75% of the oil used in Australia today - and between now and 2029 our self sufficiency in oil will go from 80% to 45% (CSIRO, Biofuels: An Issues Paper, July p2-4)
This is also occurring against an international backdrop of declining new oil discoveries whilst growth in oil demand continues, lead by strong global economic growth. The term “Peak Oil” and how best to manage it at a national level will become an increasingly important debate as the gap between demand and new supply continues to widen.
Life-cycle studies have been undertaken to evaluate the reduction of global warming gas emissions, such as carbon dioxide (CO2), when biodiesel displaces petroleum diesel.
Based on figures from the Australian Greenhouse
Office, BPL will generate a gross saving of CO2e of approximately
Data from The Australian Greenhouse Office show a 37%
reduction in the life-cycle greenhouse gas emissions when biodiesel
sourced from tallow replaces petroleum diesel and a 90% reduction for
biodiesel sourced from used cooking oils. BPL uses a combination of
tallow and used cooking oils in its process.
