N-Viro International Corporation Announces N-Viro Fuel Trial Burn Agreement in Pennsylvania

TOLEDO, Ohio, July 2 /PRNewswire-FirstCall/ -- N-Viro International Corp. (BULLETIN BOARD: NVIC.OB) ("N-Viro" or "the Company") announced today it has entered into a Memorandum of Understanding agreement (the "Agreement") with a significant electrical generating company which operates a facility in Pennsylvania. Under the terms of the Agreement, which outlines regulatory approval, testing and permitting requirements, N-Viro will supply sufficient quantities of its patented N-Viro Fuel(TM) to be blended with waste coal that will in turn be utilized in boilers owned by this energy company. The blend is expected to be tested for multiple days and different percentage mixtures. N-Viro believes the mixture of waste coal and N-Viro Fuel(TM) can be utilized as a renewable and sustainable fuel source within one or more circulating fluidized bed boilers (CFB) configured to produce steam for electric power generation.

This test is equivalent to one performed last year at Michigan State University's T.B. Simon Power Plant in East Lansing, Michigan. N-Viro anticipates similar, positive results in Pennsylvania.

The Agreement anticipates entering into a definitive arrangement once the successful test burn and permitting is completed, and would call for N-Viro to construct a facility in Pennsylvania specifically to produce N-Viro Fuel(TM).

Special Cautionary Note Regarding Forward-Looking Statements

The Company cautions that words used in this document such as "expects,""anticipates,""believes" and "may," as well as similar words and expressions used herein, identify and refer to statements describing events that may or may not occur in the future. These forward-looking statements and the matters to which they refer are subject to considerable uncertainty that may cause actual results to be materially different from those described herein. For example, while the Company expects to achieve certain revenues under the contractual arrangement with the significant electrical generating company, actual results will depend on, among other things, the amount of N-Viro Fuel(TM) used for treatment. Further, the success and profitability of the project would depend on the actual revenues and expenses of the Company, which may differ from the Company's estimates. Factors that may cause expenses to differ from the Company's expectations include, fuel and transportation costs, labor costs and costs relating to the treatment and processing of the biosolids and creation of the N-Viro fuel. In addition, while the Company believes that trends in sludge treatment are moving in favor of the Company's technology, such trends may not continue or may never result in increased sales or profits to the Company because of the availability of competing processes. All of these factors, and other factors, will affect the viability and profitability of the development, construction and operation of new facilities utilizing the Company's technologies. Additional information about these and other factors that may adversely affect these forward-looking statements are contained in the Company's reports, including its Annual Report on Form 10-KSB, and other filings with the Securities and Exchange Commission. The Company assumes no obligation to update forward-looking statements to reflect actual results, changes in assumptions or changes in other factors affecting forward-looking information except to the extent required by applicable securities laws.
