Abstract
This invention is directed to systems, devices and methods for treating organic-containing sludges and converting such sludges to high value fertilizers containing both inorganic and organic fertilizer components, which creates an inorganically-augmented bioorganic fertilizer. The invention describes methods to create a thixotrophic or paste-like material via the application of mixing energy to the organic sludge followed by an alkaline treatment and a subsequent ammoniation. The invention further describes a method to increase the plant nutrient content in the organic containing product to a level which permits the finished granular fertilizer product to compete in the commercial agricultural fertilizer marketplace. Further, the invention reduces odors associated with said organic-containing sludges.
