CleanTech Biofuels, Inc. Announces First Phase of its Municipal Solid Waste to Ethanol Project Is Now Operational

ST. LOUIS--(Business Wire)--
CleanTech Biofuels, Inc. (OTCBB: CLTH) has announced today that
the equipment purchased from the University of California at Berkeley
is now in place and operational. Testing of cellulosic feedstocks has
begun.

CleanTech is excited to begin this testing and about the potential
impact of our technologies for the reduction of garbage being disposed
of in landfills worldwide. It is estimated that Americans produce 4.4
pounds of waste per day, or 229 million tons of trash annually
nationwide. This waste represents a virtually endless source of
cellulosic feedstock for the production of biofuels that potentially
will be available to CleanTech at almost no cost, and in some
locations at a profit.

The waste disposal crisis in this Country, coupled with the Energy
Independence and Security Act of 2007 which dictates that production
of ethanol in the United States reach 36 billion gallons per year by
the year 2022, of which 20 billion gallons per year is required to be
produced from feedstock sources other than corn, positions CleanTech
Biofuels to be a leader in the cellulosic ethanol industry.

CleanTech Biofuels, Inc.

CleanTech Biofuels, Inc. is a development stage company that is
developing cutting edge waste to clean fuel technologies. We have
licensed and are developing our core patented technologies which, when
combined, can be used to convert the cellulosic material in municipal
solid waste, green waste, and other cellulosic waste materials into
fermentable sugars for the production of ethanol.

Our unique technology package positions us to be the industry
leader in using municipal solid waste (MSW) as the primary feedstock
for energy production. Municipal biorefineries developed using our
technology have the potential to:

-- Reduce the costs of transporting waste long distances for
disposal.

-- Dramatically reduce pollution released into the environment by
the disposal of municipal solid waste.

-- Reduce the amount of material going into landfills by as much
as eighty five percent.

-- Increase the amount of recyclable materials that can be
recovered from municipal solid waste.

-- Generate biofuels and other usable energy products at
competitive prices.

We believe that our combined technologies will enable the
production of ethanol from cellulosic waste streams at a lower cost
than from grain or other agricultural feedstocks. Our combined
technologies will avoid the immense consumption of water and farmland
that plague grain ethanol producers, with the added benefit of
recycling garbage and reducing the amount of waste disposed of in
landfills by as much as ninety percent.

By focusing on cellulosic biomass produced from curbside garbage
where an existing collection and disposal infrastructure has existed
for many years, our business model presents substantial economic
advantages relative to other models dependant on agriculturally
derived feedstocks or wood waste for the production of cellulosic
ethanol.
