NOVELTY - Manufacturing (M1) fertilizer comprises creating a thixotrophic paste from a composition containing biosolids, adding an oxidizing agent to the paste; adding an alkaline agent to the paste to produce a pH of at least 10; exposing the paste to ammonia at a concentration of at least 1000 ppm; adding an acid to the paste to produce heat and a pH upto 7, adding a granulating agent to the paste, extruding or granulating the paste and drying the extruded or granulated paste to a dryness of at least 90% of solids.    USE - Used for producing fertilizer, such as dry fertilizers, liquid fertilizers, ammonium sulfate, ammonium nitrate, mono-ammonium phosphate, di-ammonium phosphate, urea, urea ammonium nitrate (UAN), liquid urea, liquid N-P-K fertilizers, 16-4-8, 10-8-8 and/or 6-14-6 from biosolids such as municipal biosolids and sludges, manures and animal residuals, lagoon sludges, organic-containing sludges produced from food fermentation, sludge waste products and/or pharmaceutical fermentation waste industrial fermentation products (claimed).    ADVANTAGE - The method converts organic containing materials into safe and valuable nutrient fertilizers that are marketable in commercial agriculture. The method enables use of a combination of high concentration of inorganic plant nutrients with an unusually high concentration of organics in the same fertilizer granule and enables binding of the organics with the inorganic ammonium ions and production of a safer biosolids or organic sludge containing product, reduction of odors of the dried fertilizer product (i.e. it emits little or no odor) and increase nitrogen, phosphorus, iron, sulfur, calcium, potassium and/or other mineral content in the product (i.e. it contains at least 8 (preferably 10, especially 14)% nitrogen by dry weight and contains plant nutrient levels of iron and sulfur). By using aqueous ammonia instead of anhydrous ammonia as a disinfectant and simultaneously as a source of nitrogen, the process avoids the restrictions and prohibitions from transporting or working with the potentially hazardous anhydrous ammonia material. The thixotrophic paste is treated with an oxidizing agent, which reduces odorants emission simultaneously with increasing plant nutrient concentration. The method incorporates an alkaline treatment and ammonia exposure to create a strong antimicrobial stress on the microorganisms present immediately prior to an acidification of the material, which captures or fixes the ammonia present into ammonium salts, which are components of plant nutrient fertilizers. The process may be established close to or at existing or new wastewater treatment plants if processing municipal biosolids.
