GS CleanTech to produce biodiesel from corn ethanol co-product
GS CleanTech Corporation announced its execution of an agreement with Northeast Biofuels (NEB), to extract about 10 million gallons per year of crude corn oil from the distillers grain co-product from NEB’s new 114 million gallon per year dry mill ethanol plant scheduled to commence operations later this year.
Traditional ethanol processing converts each bushel of corn, which weighs about 54 pounds, into about 18 pounds of ethanol, 18 pounds of carbon dioxide, and 18 pounds of distillers dried grains (DDG), which contain about 2 pounds of fat. This corresponds to about 2.8 gallons of fuel production per bushel of corn. GS CleanTech's ambition is to increase this efficiency as much as possible by converting DDG into an additional stream of biodiesel.
The abundant DDGs have a low value as an animal feed (previous post). But scientists have been looking at potentially more interesting uses, and found applications as an organic fertiliser and herbicide, a solid biofuel for co-firing with coal, or a feedstock for biogas production. Others take the research a step further and see DDGs suitable for making green chemicals like polyhydroxyalkanoate (PHA) used for the production of biodegradable plastics (earlier post).
GS CleanTech thinks extracting the oil from the dried grains offers a commercially interesting opportunity for the production of biodiesel. It developed patent-pending 'Corn Oil Extraction Systems' (schematic, click to enlarge), engineered to help ethanol producers increase cash flows through the introduction of the new revenue stream. GS CleanTech provides extraction systems to participating ethanol producers at no cost to the ethanol producers in return for the long-term right to purchase the extracted corn oil at a per pound premium to its value when trapped in the distiller’s grains. GS CleanTech says its extraction technology also reduces overall plant emissions and utility costs by upwards of $1 million per year for a 100 million gallon per year ethanol plant that dries 100% of its distiller’s grains.
GS CleanTech has now partnered with NEB to demonstrate the technology. NEB is building its ethanol facility on the site of a former brewery at the 420-acre Riverview Business Park in Volney, NY, about 25 miles north of Syracuse. When the plant opens, it will annually produce 114 million gallons of corn ethanol and become the first large scale operating ethanol plant in New York State and the Northeast.
NEB and its on-site project participants, BOC Gases, and now GS CleanTech, will directly and indirectly employ approximately 100 workers, with an estimated 1,500-plus spin-off jobs created in agriculture, transportation and other sectors of the Upstate New York economy. Because of its strategic Upstate New York location, NEB will have low cost access to markets representing more than 2.3 billion gallons of potential ethanol demand in the Northeast US and Eastern Canada.

GS CleanTech’s affiliated fuel production company, GS AgriFuels Corporation, previously announced its intention to finance, build and operate a 10 million gallon per year biodiesel facility adjacent to the NEB facility. This facility will be designed to convert corn oil into biodiesel, which GS AgriFuels intends to sell locally in New York. The New York State Energy Research and Development Authority ('NYSERDA') previously awarded a $250,000 grant to support the construction of this biodiesel production facility.
GS CleanTech and GS AgriFuels have partnered in the full scale commercialization of their technologies. GS CleanTech provides technology-centric services in return for process engineering and plant construction sales, ongoing technology royalties and selected feedstock sales. GS AgriFuels provides all of the capital for the construction of the extraction and biodiesel production facilities and generates revenues through its ownership of the biodiesel production assets.
GS CleanTech and GS AgriFuels are both majority owned by GreenShift Corporation, a company devoted to facilitating the efficient use of natural resources.

The best way to [defray risk] is to implement 'plug and play' technologies that enhance the yields and operating efficiencies of the traditional ethanol production process. Our corn oil extraction technology is the first of several technologies that meet that goal that we are bringing to market to meet that objective. - David Winsness, GS CleanTech’s President and Chief Executive OfficerGS CleanTech has commenced work on the NEB extraction systems and is targeting an early 2008 commissioning:

Cattle Feeders in Nebraska have found that they get about 10% "Greater" weight gain from DDGS than from Corn. Just thought you'd like to know.
Also, removing the fat will, likely, increase the value of distillers grains as it will make them more flowable, and easier to digest.
The source of this information is an article linked in Domesticfuels.com.
Thanks Rufus, that's interesting info. I don't know much about the nutritional value of corn versus DDGs, let alone about the effects of low-fat DDGs on digestion. Will check it out!
