  • Extraction of nitrogen from organic materials through ammonification by mixed bacterial populations
    Patent number: 9809795
    Abstract: The invention provides a process for producing ammonia or ammonium from an organic material by fermenting a medium comprising organic material in the presence of a mixed bacterial population 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.

  • Method for recovering phosphorus from organic materials
    Patent number: 8691551
    Abstract: 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.
