Methods for producing a solid ammonium bicarbonate product that includes preparing an organic feedstock that contains at least one nitrogen compound by causing organic animal manure and/or organic food waste to undergo anaerobic digestion, removing solids from the organic feedstock to produce an organic liquid effluent that contains at least one of ammonium and ammonia, performing a distillation process on the organic liquid effluent to strip and concentrate a vapor mixture therefrom that contains ammonia, carbon dioxide, and water and cool the vapor mixture to produce a condensed solution containing ammonium bicarbonate and/or ammonium carbonate, contacting the condensed solution with carbon dioxide to cause an ammonium bicarbonate precipitate to form from the condensed solution, and performing an evaporation process on the ammonium bicarbonate precipitate to remove water therefrom and produce the dry, solid ammonium bicarbonate product.

The invention is directed to organic fertilizers having commercial levels of nitrogen reacted with organic substances. The scalable process comprises adding an organic processing center to a fertilizer granulation plant specifically for the treatment of organics with an acid that acidifies, heats and liquifies a mix resulting in the hydrolysis of most or all organic material and polymers. For ammonium sulfate-based fertilizer this mix is only reacted with concentrated sulfuric acid. For ammonium phosphate fertilizers, this mix is reacted with both concentrated sulfuric acid and a concentrated phosphoric acid. The acidified organic mixes are piped to an existing or new granulation plant where it is injected with anhydrous ammonia in a tee mixer/reactor that results in a partially neutralized melt. Subsequently a sterilized and liquefied organic melt is sprayed over recycled bed material for production of granules before drying. Fertilizers made as disclosed provide a “green”, dual nitrogen-release profile when applied to crops releasing a bolus of nitrogen over one to two weeks following application followed by a slow or enhanced efficiency release of nitrogen over weeks of the growing season.

The present disclosure is related to a pipe reactor. In its broadest aspect, the present disclosure is related to a method for producing a urea ammonium sulphate-based composition in a pipe reactor comprising a first and a second mixing zone. The method comprises the steps of: a) directing a liquid stream comprising ammonium bisulphate to the first mixing zone of the pipe reactor; b) directing a first stream of ammonia to the first mixing zone of the pipe reactor for reacting with the liquid stream comprising ammonium bisulphate, provided in step a), to obtain a liquid stream comprising ammonium sulphate; c) directing the liquid stream comprising ammonium sulphate, provided in step b), to the second mixing zone of the pipe reactor; and d) directing a liquid stream of urea to the second mixing zone of the pipe reactor for mixing with the liquid stream comprising ammonium sulphate.
