VitAG Corporation has developed a process to convert digested or undigested dewatered biosolids into a USEPA Class A-Exceptional Quality (EQ), high-value ammonium sulfate granular fertilizer. VitAG's fertilizer process steps include conditioning and deodorization, hydrolysis with ammonia and sulfuric acid, addition of nutrients, granulation, drying, product screening, coating, and cooling. The VitAG process incorporates ammonium salts with conditioned biosolids, to create a granular, organic ammonium sulfate fertilizer from municipal biosolids. In 2008, CDM evaluated the VitAG process for Denham Capital Management, a potential VitAG investor (Reference 1). CDM estimated capital and operating costs, product quality, intended utilization, and the value and opportunity of the product and process in the municipal biosolids service market. This report summarizes that evaluation which determined that VitAG has developed a unique process capable of producing the highest quality value-added product in the industry.
