How It’s Made

Used Cooking Oil Processing

All of the used cooking oil (UCO) collected in our trucks is shipped back to our facility where it undergoes further processing.  All UCO contains a significant amount of impurities such as water, food particles, and other debris which must be separated and filtered before it can be used for biodiesel production.

Free Fatty-Acid Reduction

All used cooking oils contain free fatty-acids (FFA) which are detrimental to the biodiesel conversion process.  When the catalyst reacts with the FFA, soap is instantly formed which hinders conversion and lowers biodiesel yield.  To mitigate this, a pretreatment reaction is required to lower the FFA before it moves further into biodiesel production.

Biodiesel Production

Biodiesel is produced by reacting vegetable oil and methanol, with the aid of a catalyst, to produce fatty-acid methyl ester (biodiesel) and glycerin.  The biodiesel is further refined to meet stringent ASTM D6751 standards while glycerin can be used in soap-making, cosmetics, and other high-value products.
