Fermentation

The process by which complex organic compounds, such as glucose, are broken down by the action of enzymes into simpler compounds without the use of oxygen. Ethanol fermentation also referred to as alcoholic fermentation, is a biological process in which sugars such as glucose, fructose and sucrose are converted into cellular energy and thereby produce ethanol and carbon dioxide.

Biorefining takes cereal grains such as wheat and breaks down the starch stored in each grain to sugars. These sugars are then fermented into alcohol and carbon dioxide. This process is very similar to what happens in a whisky distillery. The protein and other parts of the grain are converted into a high protein animal feed. Crop Energies (formerly Ensus) operates one of the world’s largest cereal grain biorefineries at Wilton in the Tees Valley in Northeast England. They refine locally grown animal feed wheat to produce over 400 million litres of bioethanol, 350 thousand tonnes of high protein animal feed and 300 thousand tonnes of carbon dioxide for use in the food and beverage industry. The biorefinery at Wilton uses electricity and steam supplied by a combined heat and power (CHP) plant.
