Dedini and Vaperma Team Up to Improve Ethanol Production in Brazil

    PIRACICABA, Brazil, Dec. 3 /CNW Telbec/ - Dedini S/A Indzstrias de Base
and Vaperma Inc. signed a cooperation agreement to introduce Vaperma's
Siftek(TM) dewatering and dehydration systems in Brazilian ethanol market. The
agreement involves the construction of a first commercial plant in an
operating ethanol plant in Brazil by Q3- 2008.
    This relationship was developed following many months of collaboration
between both Dedini and Vaperma to validate the technology and its benefits to
the Brazilian market. The application of Siftek(TM) technology is especially
beneficial for the Brazilian sugarcane to ethanol producer as it provides a
cost effective method for the alcohol production in order to increase power
production from the significant steam savings. Vaperma has developed a
breakthrough solution to remove water from ethanol blends by entirely
replacing rectification column and/or dehydration unit such as molecular sieve
and cyclohexane. Conventional alcohol distilleries are known to consume huge
amounts of steam which might be more wisely used to produce additional revenue
from the sale of bio-electricity.
    "To find new technologies to improve the efficiency of the transformation
of sugarcane into ethanol is one of the great challenges for maintaining
Brazilian competitiveness in the international market", said Mr. Jose Luiz
Olivério, Senior VP Technology of Dedini. "Being the world's largest producer
of fuel alcohol from sugarcane, Brazil possesses cutting edge technologies at
the lowest manufacturing cost and is also the largest exporter of fuel-grade
    "Vaperma's Siftek(TM) system is being tested successfully for over a year
in an operating corn-based ethanol plant in Canada and offers Brazilian
sugarcane ethanol producers an immediate return on investment with additional
bio-electricity revenues generated by the significant reduction of steam
consumption" said Claude Létourneau, President & CEO of Vaperma.
    Dedini continues to evolve and expand as one of the leading global
technology providers in the ethanol market. This latest partnership with
Vaperma confirms Dedini's commitment to stay at the forefront on innovation in
the sugar/alcohol sector.
