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.
