In the production of ethanol, a valuable by-product of the spent grain is produced. Whether the spent grain is from corn, wheat, barley or rye, it has a high value once dried. The main use of the DDG or the DDGS is in the animal feed industry where the product is used in e.g. ruminant diets. 
 
Haarslev Industries supplies driers, evaporators, and complete installations for dewatering and drying. Applications include waste streams from the grain processing industry such as distilleries, breweries, gazohol plants, corn wet milling and the starch industry.
