GreenShift Corp. announced that the U.S. Patent and Trademark Office will issue a patent titled "Method of Freeing the Bound Oil Present in Whole Stillage and Thin Stillage" on Oct. 27 to GS CleanTech Corporation, a wholly-owned subsidiary of GreenShift.

According to Greenshift, by extracting the corn oil before the grains are dried, an ethanol plant can realize an added benefit from selling the corn oil. In addition, an efficiency improvement is created by removing the oil, which acts as an insulator during the drying process. GreenShift estimates an ethanol plant's savings at roughly 13 cents per gallon of ethanol.

The second patent award announcement comes just one week after GreenShift announced it had been awarded a patent titled "Method of Processing Ethanol Byproducts and Related Subsystems."
