NEW YORK -- GS AgriFuels Corporation plans to co-locate integrated corn oil-to-biodiesel production technologies on-site at ethanol production facilities.



GS AgriFuels' biodiesel production technologies, developed by recently acquired NextGen Fuel, Inc., are modular and can be integrated directly into existing and new ethanol production facilities in a plug-and-play manner. The technologies allow host ethanol facilities to quickly and cost-effectively participate in the benefits of corn oil biodiesel production.

An ethanol facility converts 36 million bushels of corn into 100 million gallons of ethanol and 320,000 tons of DDG. DDG has a value of only $0.035 per pound while fuel prices exceed $0.30 per pound, and therefore it is highly advantageous to convert as much as possible of this DDG byproduct into fuel.



GS CleanTech's patent-pending corn oil extraction technology extracts roughly 7 million gallons of the fat in the DDG in the form of corn oil that can then be converted into biodiesel on close to a 1:1 volumetric basis.



GS AgriFuels' patent-pending NextGen biodiesel process technology leverages innovative process intensification techniques to accelerate and enhance traditional biodiesel reaction kinetics, thus decreasing process time, reducing energy and raw material needs, and increasing product quality. These benefits translate to increased capital and operating cost efficiencies at smaller scales as compared to traditional biodiesel process technologies, and much quicker lead times.



Used in concert, both technologies increase the corn to fuel yield by roughly 7 percent and corresponding revenues by more than 6 percent.



GS AgriFuels was founded to produce and sell clean fuels from agriproducts in innovative ways. GS AgriFuels acquired NextGen Fuel, Inc. in October 2006.



GS AgriFuels is about 90-percent owned by GreenShift Corporation, a company devoted to facilitating the efficient use of natural resources.



GS CleanTech provides applied engineering and technology transfer services based on clean technologies and process innovations that make it cost-effective and easy to recycle and reuse resources. GS CleanTech is about 80-percent owned by GreenShift Corporation.



GS CleanTech's Corn Oil Extraction System(TM)



Currently, the majority of the ethanol produced domestically is based on a dry milling technique that converts corn into ethanol. The corn is milled and then mashed with a combination of heat and enzymes that convert the starch in the corn into fermentable sugars. This mash is then cooled and mixed with yeast to create a fermented mash which is then separated into alcohol and stillage.



The alcohol is distilled and dehydrated into 200 proof fuel-grade ethanol. The stillage is sent through series of centrifuges and evaporators and then to a rotary dryer to reduce moisture. The output of the drying stage is a co-product called distillers dried grains ("DDG") which is conventionally sold as a livestock feed.



GS CleanTech's patent-pending corn oil extraction technology intercepts the whole stillage flow in between the distillation stage in the final drying stage. GS CleanTech routes the whole stillage through its extraction technology where up to 75 percent of the total oil within the corn is extracted using safe, non-solvent based extraction methods.



The crude corn oil is then routed to storage for use as a raw material for biodiesel production and the now defatted whole stillage is returned to the drying stage of the ethanol production process where it is efficiently dried into defatted DDG.
