HOW DOES THE ETHANOL PRODUCTION PROCESS WORK?

The process of producing ethanol takes many steps. Click here to download our process flow chart.

 

WHAT IS ETHANOL?

Ethanol is an alcohol that is used in gasoline resulting in a cleaner-burning fuel with higher octane. Ethanol is currently blended into more than 50 percent of the nation's fuel supply.

Ethanol has been blended in gasoline for decades, and billions of miles have been driven on ethanol-blended fuels. Learn more on our ethanol information page.

 

WHAT IS WDGS?

In many ways we are a distillers grain plant with ethanol as our co-product. Distillers grains are well known as a good source of “bypass” protein and nutrients, containing over 30% protein compared to approximately 20% in corn gluten feed (dry matter basis) but similarly high in digestible fiber and low in starch. Extensive research has shown the value of feeding distillers grains to growing-finishing cattle as well as lactating dairy cows. When fed to dairy cows, distillers grains are a high-quality, economical source of crude protein, phosphate and net energy for lactation. Learn more on our WDGS page.

 

HOW DOES ETHANOL PERFORMANCE COMPARE TO GASOLINE?

One gallon of pure ethanol contains about 66 percent as much energy as a gallon of gasoline. A gallon of E85, a common blend of 85 percent ethanol and 15 percent gasoline, contains about 71 percent as much energy as a gallon of unblended gasoline.

Drivers who use E85 pure ethanol can expect about 15 percent less fuel economy than they would with gasoline. Other performance factors such as power, acceleration, and cruising speed are essentially equivalent in vehicles burning E85 and conventional fuels.

 

WHAT IS THE SHELF LIFE OF WDGS?

The shelf life of WDGS is very dependant on the ambient temperature and storage condition. If loosely piled in the winter time it can last from 2 to 3 weeks, in the summer time this can be reduced to as little as 3 to 5 days. If the WDGS is packed much the same way as silage and sealed from oxygen, they can last indefinitely (this process could be compared to canning sauerkraut). Calgren has the same concern as area neighbors, if the WDGS is allowed to remain on site and become spoiled, this substantially reduces the feed value of the product through undesirable odor and heating.
