Cooking oil, palm oil biodiesel can reduce emissions relative to diesel mongabay.com November 28, 2007
The report, The greenhouse and air quality emissions of biodiesel blends in Australia, also assesses emissions and environmental impacts of biodiesel produced from other sources including used cooking oil, tallow (rendered animal fat), and canola. It finds that highest savings -- an 87 per cent emission reduction -- are achieved by replacing conventional diesel with biodiesel from used cooking oil. Imported palm oil from long established plantations produces an 80 percent savings. "Palm oil can produce up to an 80 per cent saving in emissions provided it is sourced from pre-1990 plantations," said lead author Dr Tom Beer of CSIRO. "The palm oil source is critical as product from plantations established on recently dried peat swamps or cleared tropical forest will in fact have higher greenhouse gas emissions than regular diesel due to factors such as land clearing."
"The results of this study show biodiesel has the potential to reduce emissions from the transport industry," Dr. Beer added. The transportation sector is Australia's third largest source of emissions after electricity generation and agriculture. The Report (PDF) Credit: Thank you to Biopact for the tip on the report
