NATCHEZ, MS -- (MARKET WIRE) -- 10/17/2006 -- U.S. Sustainable Energy Corp., A Mississippi Corporation ("US Sustainable," "USSEC" or "the Company") (PINKSHEETS: LFZA), announced today that USSEC has patent pending technology related to gaseous and liquid biofuels made from a natural feedstock, such as soy, corn, their by-products, or any combination thereof. It is believed that the unique chemical composition resulting from USSEC's proprietary process results in the inventive gaseous biofuel, which has been shown to exhibit higher thermal energy than natural gases, with a minimum of 1800 BTU/standard cubic foot.

With respect to its liquid biofuels, like its gaseous biofuels, USSEC has independent laboratory tests verifying unexpected and surprising physical properties, such as a heat capacity of at least 120,000 BTU/gal, which is greater than traditional biodiesel. USSEC's inventive liquid biofuel also exhibits extremely low pour and cloud points, such as less than at least -70°F.

In addition to the previously described biofuels, USSEC's inventive process allows even the resulting, solid by-products to be used in potentially viable commercial applications. As a result, patent applications have been filed to cover methods of making these solid by-products, which include an organic fertilizer containing organic nitrogen, potash (K2CO3), and orthophosphate, as well as vegetable pigments made from the previously described natural feedstocks.

Mr. John Rivera, CEO of USSEC, stated, "With this broad patent protection and our proprietary knowledge of the process, we own the molecular structure of this totally unique fuel. We are extremely grateful for the detailed work that has been done by our law firm Finnegan Henderson (www.finnegan.com). Every day we are bringing America one step closer to energy independence."

About U.S. Sustainable Energy

USSEC holds patent pending technology for a new breakthrough biofuel and carbon based fertilizer. USSEC has successfully demonstrated the most cost effective method of producing biofuel estimated at $.50/gallon according to exhaustive studies and independent Lab confirmation. The company has developed the process, units and catalyst that will transform agricultural biomass into biofuel and fertilizer. This technology offers a solution for foreign oil dependence, balancing industrial and agricultural concerns with environmental issues and stabilizing and eventually reversing global greenhouse gas emissions. USSEC's research and development has successfully demonstrated the core technology in its fully functional facility located in Port Gibson, MS. The company is currently pursuing fully scalable implementation and deployment at further locations. Unlike other biomass gasification, the USSEC process can operate at a variety of scale, converting even waste biomass into fuel and fertilizer. The fuel produced will ultimately be more valuable than ethanol or methanol, and the USSEC process can convert biomass materials at an efficiency that cannot be matched by currently planned operations. In addition, unlike virtually all other approaches for biomass to energy, which deplete soil nutrients, the USSEC process restores and enhances soil mineral and carbon content. As a direct result of this revolutionary approach to integrated energy and fertilizer production from biomass, the USSEC process effectively removes Greenhouse Gases from the atmosphere, and can do so profitably before the value of Green Certificates and Carbon Credits are considered.
