GreenShift has announced that its NextDiesel branded corn oil derived biodiesel has superior cold flow properties compared to biodiesel produced from soybean oil, a conventional biodiesel feedstock.

GreenShift's patent-pending corn oil extraction technology ("COES") extracts inedible crude corn oil from distillers grain, a co-product of ethanol production, for conversion into biodiesel.

GreenShift's extraction technologies have the capability of extracting more than 6.5 million gallons of crude corn oil for every 100 million gallons of corn ethanol produced. According to the Renewable Fuels Association, more than 8.9 billion gallons of corn-derived ethanol were produced during 2008.

This equates to a potential U.S. total annual production of about 580 million gallons per year of inedible corn oil that is recoverable with GreenShift's patent-pending corn oil extraction technologies.

With cloud points ranging between -3C and -5C, GreenShift's NextDiesel branded corn oil biodiesel (corn oil methyl ester, or "CME") consistently achieves superior cold flow properties as compared to biodiesel produced from soybean oil derived biodiesel (soy methyl ester, or "SME").

SME is well known for its benchmark high quality and good cold flow properties in the U.S. markets.

Patrick Bush, GreenShift's vice president of biodiesel technology, commented, "The specifications of NextDiesel CME translate to enhanced quality and reliability for cold weather applications as compared to SME or other conventional biodiesel products."

Mr. Bush heads up GreenShift's biodiesel technology development activities with Phil Bollheimer, GreenShift's director of process design, and other key members of GreenShift's process engineering team.

Mr. Bollheimer continued, "It is easy to assume that the clear, water white biodiesel that is produced by energy and carbon intensive methyl ester distillation technologies has superior quality. While this is generally true as compared to most conventional feedstock-derived biodiesel fuels, the specifications of GreenShift's NextDiesel CME are in fact superior due, in part, to the fact that distillation technologies cannot remove the hidden and unfavorable impurities that have molecular weights close to the saturated and unsaturated components of biodiesel."

Bush concluded, "We are shipping NextDiesel CME today. Our production data demonstrates that the almost 600 million gallons per year of inedible crude corn oil that are recoverable with GreenShift's patent-pending corn oil extraction technologies can make a significant contribution to the renewable fuels industry not just in volume and environmental benefit but in fuel quality, as well."

GreenShift's array of biodiesel process technologies produce an exceptional finished product that meets the cold soak filtration testing requirements of the newest ASTM specification for biodiesel.

Focus on Ethanol Production

GreenShift is the inventor and industry pioneer of corn oil extraction technology. With years of know-how, six modular extraction systems in operation, and over 65,000 hours of operational run time in several different ethanol facilities, GreenShift has proven the reliability of its extraction technology and established its technology leadership.

GreenShift is focused on delivering technologies and process innovations to the existing corn ethanol industry with a view towards maximizing the yield and efficiency of corn-based ethanol facilities to allow production of more cost effective ethanol and biodiesel.

GreenShift's view is that the established first-generation corn ethanol infrastructure is the only practical pathway in North America currently available to cost-effectively increase the production and use of carbon-neutral biofuels on globally-meaningful scales.

To accomplish this in a competitive and environmentally superior way, first generation corn ethanol facilities will need to evolve to achieve significantly improved production efficiencies. GreenShift intends to contribute to that evolution.

GreenShift's currently available offerings include its integral corn oil extraction and biodiesel production systems. GreenShift is also developing new technologies for application at corn ethanol facilities designed to improve food and fuel yields, increase production efficiencies and enhance the economic and environmental benefits of ethanol production.
