The Transesterification Process Explained Simply
From vegetable oils to clean-burning biodiesel — a clear look at how B-100 is actually made at our facilities.
Biodiesel sounds high-tech, but the chemistry behind it is elegantly simple and more than a century old. The process is called transesterification, and understanding it helps explain why biodiesel is such a clean, consistent fuel. Here's the whole journey, minus the jargon.
Step 1: Feedstock preparation
It starts with renewable oils — vegetable oils or collected used cooking oil. The feedstock is filtered, de-watered, and tested. Quality control at this stage matters enormously: clean input is the first ingredient of clean fuel.
Step 2: The reaction
The oil is mixed with an alcohol (usually methanol) and a catalyst, then heated and stirred in a reactor. The catalyst encourages the oil molecules — triglycerides — to swap their glycerin "backbone" for the alcohol. The result: fatty acid methyl esters, which is the chemical name for biodiesel, plus glycerin as a by-product.
Step 3: Separation
Biodiesel and glycerin don't mix, so after the reaction they naturally separate into two layers. The glycerin is drawn off and refined for use in other industries — nothing is wasted.
Step 4: Washing and purification
The raw biodiesel is washed and dried to remove traces of catalyst, alcohol, and soap. What remains is pure B-100.
Step 5: Testing and certification
Every batch is laboratory-tested against fuel standards — density, viscosity, flash point, cetane, sulphur content — before it leaves the plant. Under our ISCC and ISO systems, each parameter is documented and traceable.
Why the process matters
Because transesterification transforms the oil at the molecular level, the finished biodiesel burns cleanly and consistently — it isn't just filtered oil. That is the difference between a genuine engineered fuel and a shortcut, and it's why properly produced B-100 protects engines rather than harming them.
