We were incorporated in Delaware in April, 1993, and became a public company in October 1993. We own and license the N-Viro Process, a patented technology to treat and recycle wastewater sledges and other bio-organic wastes, utilizing certain alkaline and mineral by-products produced by the cement, lime, electric utilities and other industries.

Our business strategy went from being a low cost provider of a process to marketing the N-Viro Process, which produces an "exceptional quality" sludge product, as defined in the 40 CFR Part 503 Sludge Regulations under the Clean Water Act of 1987 (the "Part 503 Regs"), with multiple commercial uses. In this strategy, the primary focus is to identify allies, public and private, who will build and operate an N-Viro facility. To date, our revenues primarily have been derived from licensing the N-Viro Process to treat and recycle wastewater sludge generated by municipal wastewater treatment plants and from the sale to licensees of the alkaline admixture used in the N-Viro Process. We have also operated N-Viro facilities for third parties on a start-up basis and currently operate one N-Viro facility on a contract management basis. At the end of 2006 we acquired and now manage a merchant facility which accepts wastewater sludge from several sources in the Orlando area.
