Biodiesel is a renewable biofuel derived from vegetable oils, animal fats, used cooking oil, and algae oils. Chemically, it consists of Fatty Acid Methyl Esters (FAME) produced through transesterification of triglycerides with methanol in the presence of a catalyst.
Unlike fossil diesel, biodiesel is largely carbon-neutral, as CO₂ released during combustion is offset by carbon absorbed by feedstock crops during growth. Biodiesel can be used as B100 or blended with conventional diesel.
Feedstock Sources
Vegetable oils (soybean, palm, rapeseed, sunflower)
Animal fats (tallow, lard, poultry fat)
Used cooking oil (UCO)
Algae oil (next-generation feedstock)
Production Process – Transesterification
Feedstock pretreatment and purification
Transesterification reaction producing FAME and glycerol
Separation of glycerin by-product
Washing and purification
Drying and quality testing to ASTM / EN standards
By-product: Crude glycerin used in pharmaceuticals, cosmetics, and chemicals
