KyBiofuels

Griffin Industries, a subsidiary of Darling Ingredients, is located in Butler, KY. They utilize natural, renewable resources such as vegetable oils, animal fats and recycled cooking oils to make biodiesel for use by private companies and in the local retail fuel supply. They collect and repurpose billions of pounds of inedible materials annually into useable and specialty ingredients.

 

Biodiesel is produced across North America and the world. There are three plants in Kentucky and three plants in Indiana producing Biodiesel.

The United States, Germany, Brazil, Argentina, France, and Indonesia are the leading Biodiesel-producing countries.

Who Makes Biodiesel

in Kentucky?

How It's Made


Biodiesel is made through a chemical process called transesterification whereby the glycerin is separated from the fat or vegetable oil. Most biodiesel is made from soybean oil or used cooking oil from the restaurant industry, but it can be made from most any renewable plant or animal fat. 

The process of transesterification leaves behind two products -- methyl esters (the chemical name for biodiesel) and glycerin (a valuable byproduct usually sold to be used in soaps and other products).

Biodiesel

Owensboro Grain Company produces a vast array of products from soybeans in western Kentucky. They began refining biodiesel in 2008 and have the ability to produce 45 million gallons per year. Because of their location on the Ohio River, they are able to respond quickly to market demands by being able to ship by truck, rail, or river and can supply to the world marketplace.
