Only <br />one of these, the Utashinai City plant, can be considered commercial; the others have been only <br />operated as pilots or intermediately operated for testing purposes. A pilot plant in Ottawa, <br />Canada is currently being tested by Plasco Energy and has only been intermediately operated <br />with a maximum continuous runtime of 36 hours using a pre - sorted, post - consumer waste stream <br />as feedstock. Plasco is currently in the process of converting this plant to commercial <br />operations, having successfully negotiated an operating contract with the City of Ottawa. <br />Exhibit 12 -12.
