Biodiesel is produced by transesterification of animal and vegetable oils with methanol or ethanol. It has a high cetane number, good combustion performance, and low sulfur and aromatic hydrocarbon content, which can reduce particulate matter (PM) and sulfur dioxide (SO₂) emissions. Biodiesel is highly compatible with petroleum diesel and can be used directly or blended with it.
