MIAMI, FL -- (MARKET WIRE) -- 04/23/08 -- Stock Market Alerts' performance stock list includes: CleanTech Biofuels, Inc. (OTCBB: CLTH), Sunoco, Inc. (NYSE: SUN), Pacific Ethanol, Inc. (NASDAQ: PEIX), ConocoPhillips (NYSE: COP).

Having announced last week a licensing agreement with HFTA and the University of California, Berkeley, CleanTech Biofuels, Inc. (OTCBB: CLTH) should have the attention of investors this morning. Yesterday after the markets closed, the company issued a press release announcing that it has engaged Hazen Research, Inc. to construct and operate the pre-commercial stages of our Municipal Solid Waste to Ethanol project at Hazen's eight acre research facility in Golden, Colorado.

More good news for CLTH! In late January of this year, CleanTech Biofuels purchased a reactor system from the Forest Products lab at the University of California at Berkeley and reassembled it at Hazen. This reactor system has successfully demonstrated the effectiveness of our HFTA cellulose conversion technology on wood waste feedstocks at Berkeley. Currently we are utilizing this reactor system at Hazen in the first phase of our project to optimize reaction conditions for our Process Engineered Fuel derived for municipal solid waste as well as other cellulosic feedstocks including corn stover, wood waste, and switch grass.

Hazen Research has an experienced and competent staff supported by the laboratory and pilot plant facilities necessary to apply the most appropriate technology to evaluate any industrial, commercial, and environmental issues we may encounter as our project moves from development to commercialization. They maintain all permits, governmental (Federal, State and Local) permits, licenses, and other approvals necessary to complete this project.

Watch this company very closely! Last week the company reported that it has entered into an exclusive worldwide sublicense agreement with HFTA of Livermore, California to license technology developed by scientists at the University of California, Berkeley. The patented technology utilizes nitric acid rather than sulfuric or hydrochloric acid to hydrolyze cellulosic material for the production of ethanol and other fuels from biomass. Sulfuric or hydrochloric acids are typically used for most thermo-chemical hydrolysis processes. CleanTech believes that the HFTA/University of California Berkeley nitric acid process represents state-of-the-art technology in the cellulosic ethanol industry.

In addition to the company's exclusive rights to utilize municipal solid waste as feedstock for the HFTA technology, CleanTech has also obtained a nonexclusive worldwide license for all other cellulosic biomass feedstocks for the production of ethanol. The licensed technology is described in U.S. Patents No. 5221357, 5366558, 5536325, 5628830, and 6019900. The sublicense agreement is with HFTA, a California corporation formed by the developers of the technology while at the University of California at Berkeley

Before the news was released, CLTH closed Tuesday at $1.10 a share.
