Biodiesel could reduce greenhouse gas emissions
Using pure biodiesel or blending the energy source with standard fuel could reduce the transport sector's impact on climate change, a new report has claimed.
The Australian study, undertaken by the Commonwealth Scientific and Industrial Research Organisation, looked at the carbon emission levels and environmental impacts of biodiesel produced from sources including cooking oil and imported palm oil.
While the researchers found emissions were reduced by various forms of biodiesel, the most significant savings came from using cooking oil in place of conventional base diesel, while palm oil also offered significantly benefits.
"The results of this study show biodiesel has the potential to reduce emissions from the transport industry," said the report's author, Dr Tom Beer.
"The greenhouse gas savings do however depend on the feedstock used to produce the biodiesel. The highest savings are obtained by replacing base diesel with biodiesel from used cooking oil, resulting in an 87 per cent emission reduction," he added.
According to Reuters, the European Union recently announced that all biofuels used in Europe must produce at least ten per cent less emissions than fossil fuels.
