Biodiesel is a renewable, cleaner-burning fuel derived from biological sources like vegetable oils (e.g., palm, soy) or animal fats, reducing greenhouse gas emissions compared to conventional diesel.

It is commonly blended with petroleum diesel (e.g., B7, B10, B15) to operate in existing diesel engines without major modifications.

Key Aspects of Biodiesel:

Production: Produced through a chemical process (transesterification) that transforms oils/fats into Fatty Acid Methyl Esters (FAME).

Benefits: Offers up to 80% fewer greenhouse gas emissions and improves energy security.

Physical Properties: B100 (100% biodiesel) has a flash point of 130°C and a kinematic viscosity between 1.9-6.0 mm²/s.

Quality Standards: Programs like BQ-9000  help monitor quality, ensuring it meets standards like ASTM D6751 .
