Naturally Advanced Technologies Signs Amended Agreement with the National
Research Council of Canada to Collaborate on Research for the Production of
Cellulosic Ethanol from Sustainable Feedstock

- Research Intended to Develop New Enzyme Technology for Cellulosic Ethanol Manufacturing -

PORTLAND, OR, Feb. 22 /CNW/ - Naturally Advanced Technologies Inc. (NAT, OTCBB: NADVF, TSXV: NAT) amended its agreement with the National Research Council (NRC) of Canada to include collaboration on cellulose technology research for the production of cellulosic ethanol from sustainable feedstock, such as corn stalks and straws, which is the unexploited byproduct in agri-food production.

    
        -  The NAT - NRC collaboration began in 2004 and was extended in 2007
           for the design and construction of advanced enzyme technology for
           the extraction and cleaning of industrial hemp fiber for the
           textile sector, as spearheaded by Dr. Wing Sung.
        -  As this research is in the final stages, the two parties have
           agreed to divert existing funding commitments to pursue additional
           opportunities for the advanced enzyme technology, namely in
           cellulosic ethanol.
        -  Currently, bio-ethanol is produced by the fermentation of yeast
           with glucose that comes from corn starch, which requires high
           levels of fertilizer and energy use and results in high levels of
           waste materials.
        -  The next research phase will address the inefficient enzymatic
           conversion of cellulose to glucose for the subsequent fermentation
           to ethanol by developing technology via protein engineering and an
           efficient hydrolysis protocol.
        -  The extended agreement expires May 9, 2012, and maintains the same
           parameters for NAT to secure the exclusive rights of the
           intellectual property.
    

"Leading this project will be Jeremy K. Jones of our board of directors," stated Ken Barker, CEO of NAT. "Jeremy has extensive experience with cellulosic ethanol and advanced materials as vice president for Koch Genesis, the venture arm of Koch Industries that includes Koch's operating businesses INVISTA, Georgia-Pacific and Flint Hills Resources. I am confident he will provide excellent direction as we continue collaborating with the NRC to build our advanced enzyme treatment technology portfolio."

"We are thrilled that Dr. Sung will again serve as Principal Research Officer for this project. He has received numerous awards for his leadership and promotion of the life sciences industry and collaboration within the industry on a national scale. His study of proteins and enzymes was pivotal in developing CRAiLAR(R), NAT's organic enzyme bath process that transforms hemp into fiber that can be used in traditional cotton knitting systems, thereby enabling hemp to enter mainstream apparel production. In addition, Dr. Sung designed enzymes that reduce toxic effluent in the pulp and paper industry," concluded Barker.
