Four Rivers Signs Lease Agreement with Grean Technologies for STT(R) Reactor System

Four Rivers Signs Lease Agreement with Grean Technologies for STT(R) Reactor
System

CALVERT CITY, KY, Nov. 30 /PRNewswire-FirstCall/ - Four Rivers BioEnergy Inc.
(OTCBB: FRBE) ("4Rivers" or "Four Rivers" or "the Company") today announced
that the Company has entered into a lease agreement with purchase options with
Grean Technologies of Hamilton, Ohio for a Four Rivers STT(R) Reactor System.
Grean Technologies will be using the system for process intensification
research for their flavors and fragrances business. The 4Rivers STT(R) Reactor
System to be supplied is a 100ml volume system and was part of the assets
acquired by 4Rivers from Kreido BioFuels, Inc. in March 2009.
Gary Hudson, Managing Director of the STT Business and Senior Vice President
of Operations for Four Rivers stated, "This is another significant step in the
commercialization of the STT(R) Reactor System. We are in the process of
establishing a world wide network of agents to bring this technology to
market."
David Moats, Principal of Grean Technologies stated, "We are excited to
enhance our flavor and aroma productions with cutting edge technologies like
the STT system. Having seen the bench-top Magellan STT system at the US EPA
labs in Cincinnati, OH, we have leased the larger Innovator STT system.
This system will be utilized to provide sampling and small production runs
before moving to full commercial scale quantities. The Innovator SST system
will allow Grean Technologies to supply our clients with quality products
while passing along cost efficiencies and reducing the environmental impact of
chemical production."
STT(R) Reactor Systems are based on extensively tested and proven cutting edge
process intensification technology developed over the past 10 years. The
system has a myriad of industrial applications for the bioenergy, chemical,
pharmaceutical, food, flavors, fragrances, nanotechnology, and other
industries.
STT(R) technology creates significant increases in reaction rates where
momentum, heat or mass transfers are involved. A significant benefit of the
STT(R) technology is that optimization can be determined on the bench scale
(Magellan(R) series), which then easily scales up through the pilot production
(Innovator(R) series) and then into the commercial scale.

Some of the advantages that the STT(R) reactor technology brings include:
- Rate enhancement
- Improved conversion
- Selectivity enhancement
- Continuous processing versus batch
- Improved temperature and reaction environment control
- Reduced catalyst consumption and solvent use
- Reaction of normally immiscible materials
- Mixing of materials with large relative viscosities
- Improved safety in handling toxic and explosive materials
- Rapid and efficient cleaning
- Small reactor foot print compared to conventional reactors

The STT(R) Reactor System is based on 4Rivers' own intellectual property and
relies on technology and a combination of 12 issued patents, additional
patents pending, copyright, trade secret laws, and know-how.
