CleanTech Biofuels Finalizes Transaction With World Waste Technologies

CleanTech Biofuels, Inc. (OTC Bulletin Board: CLTH), formerly a sublicensee of World Waste Technologies' patent (U.S. Patent No. 6,306,248 and Patent Cooperation Treaty, International Application No. PCT/US01/50049, Method for Transforming Diverse Pulp and Paper Products into a Homogenous Cellulosic Feedstock), announces that it has acquired that patent. CleanTech Biofuels is now able to file new United States and international patents based on the combined technologies described in the patent and those of Biomass North America Licensing.

CleanTech CEO, Ed Hennessey, noted, "We are very excited to have completed this transaction, as this acquisition creates many new opportunities for our company."

The newly acquired patent relates to the proprietary Pressurized Steam Classification process that CleanTech uses for cleaning and separating municipal solid waste into its component parts. This process creates a homogenous biomass that can be used as a renewable feedstock for the production of alternative energy in a variety of different applications. CleanTech is implementing its technology at a commercial site in Chicago, Illinois and is evaluating a number of additional sites for commercial development.
