The invention provides a process for producing phosphate from an organic material, the method including the steps of (a) fermenting an organic material in a medium in the presence of at least one microorganism, wherein the fermenting is under conditions, and for a sufficient period of time, to produce a fermentation product; (b) treating the solids of the fermentation product with acid, in a medium, e.g., aqueous medium, to solubilize phosphates from the fermentation product; wherein the organic material, and thus the solids of the fermentation product, includes bone suitable for extraction of phosphates.

Method for recovering phosphorus from organic materials

The invention provides a process for producing ammonia or ammonium from an organic material, the method by contacting the organic material with at least one hydrolytic enzyme, in a medium, to produce a medium including hydrolyzed or partially hydrolyzed organic material suitable for microbial fermentation. The hydrolyzed or partially hydrolyzed medium with organic material is then fermented in the presence of at least one microorganism capable of ammonification, wherein the fermenting is under conditions, and for a sufficient period of time, to produce a fermentation product that comprises ammonia or ammonium. The organic material includes nitrogenous compounds suitable for conversion to ammonia or ammonium.
