What is biodiesel?

Biodiesel is a renewable biofuel that is clean-burning and offers a replacement or supplement to regular diesel fuel. Carbon emissions from biodiesel are 50 to 80% less than diesel fuel. It is produced from a variety of feedstocks from used cooking oil, to animal fats and, as in our case, pure vegetable oil. Learn more about biodiesel here.

Production Process

Through a process called transesterification, our biodiesel is created from a chemical reaction involving our soybean oil, methanol and a catalyst. The result of this process is the production of biodiesel and the by-product crude glycerin. The ratio is nearly 1:1 in regards to soybean oil input to biodiesel output.

Our Products

B100 Biodiesel is a bulk fuel product consisting of 100% unblended biodiesel. B99.9 Biodiesel is a bulk fuel product consisting of 99.9% biodiesel, blended with 0.1% clear diesel fuel. This product is an option relevant to IRS credit incentives. Both biodiesel products meet the requirements of ASTM D 6751 and renewal identification numbers (RINs) are assigned and transferred with each product sale.

Glycerin is a crude bulk by-product of the biodiesel production process.

Flexible Delivery

Our facility is equipped to load Biodiesel by truck and railcar.  Most of our customers lift product at our facilities via their own or 3rd party trucking fleets.  However, we have the flexibility to load customer owned railcars, or we can accommodate delivery via our fleet of Incobrasa tanker railcars.
