Biodiesel is a renewable, biodegradable fuel that is manufactured using a chemical process which converts oils and fats of natural origins into fatty acid methyl esters (FAME). Biodiesel is designed to be used in standard diesel engines and can be blended with petroleum diesel at various levels or used in its pure form. It provides an environmentally friendlier alternative to traditional fossil fuel diesel as it helps reduce greenhouse gas emissions, particulate pollution and dependence on finite oil resources.
The oils and fats used for biodiesel production are typically vegetable oils like soybean oil or canola oil, animal fats, recycled grease, or even algae. The production process involves transesterification, where the glycerin is separated from the fat or vegetable oil, leaving behind methyl esters (the chemical name for biodiesel) and glycerin (a valuable byproduct usually used in soaps and other products).
Biodiesel can be used in any diesel engine when mixed with mineral diesel, and no modifications are necessary for blends of 20% biodiesel (B20) or less. Higher percentages of biodiesel (B100, for example) may require certain engine modifications to avoid maintenance and performance issues due to biodiesel’s different chemical properties.
