The present application relates to systems and methods for processing organic material. The methods may include extraction of biochemical nutrients from organic material, such as food scraps. The method can include comminuting the organic material to form a slurry from components comprising liquid and organic material; combining the slurry with microorganisms, such as a yeast, under aerobic conditions to form a mixture of the slurry and yeast; aerating the mixture; and forming a biomass and a nutrient-rich broth, in which the biochemical nutrients are stabilized and anabolized. The systems may, in some embodiments, be configured to perform the methods of processing organic materials.

1. A system for stabilizing biochemical nutrients extracted from organic material, the system comprising: a comminution device configured to comminute the organic material into a slurry, the slurry containing liquid and particles of organic material, the biochemical nutrients from the organic material being extracted into the liquid;a liquid source fluidly coupled to the comminution device, configured to supply an amount of liquid to the comminution device;a biological tank configured to receive the slurry, wherein the biological tank contains a yeast in aerobic conditions, the yeast and the slurry forming a mixture and the yeast stabilizing the biochemical nutrients in the mixture; andan aeration system operably coupled to the biological tank to provide oxygen to the mixture and maintain an oxygen content in the mixture at approximately 0.5-3 ppm, the aeration system comprised of a blower coupled to a bubbler, the bubbler being comprised of a tube extending vertically through the mixture and having a distal end located in proximity to the bottom of the biological tank, the tube having an opening at the distal end through which the oxygen bubbles into the mixture, wherein the aeration system maintains the mixture in the biological tank in a non-turbulent quiescent state while providing oxygen to the mixture. 2. The system of claim 1, wherein the aeration system is configured to homogenously mix the mixture while the mixture is maintained in the non-turbulent quiescent state. 3. The system of claim 1, wherein the particles of organic material in the slurry have a particle size of less than approximately 3 mm. 4. The system of claim 1, further comprising a pump fluidly coupled to the comminution device and the biological tank, wherein the pump is configured to transport the slurry from the comminution device to the biological tank. 5. The system of claim 1, further comprising a processing tank fluidly coupled to the comminution device, configured to receive the slurry from the comminution device. 6. The system of claim 5, wherein the processing tank is configured to heat the slurry in order to pasteurize harmful microorganisms in the slurry. 7. The system of claim 5, wherein the processing tank is configured to receive hydrolytic enzymes to hydrolyze particles of organic material in the slurry. 8. The system of claim 1, wherein the yeast in the in the biological tank comprises Saccharomyces cerevisiae. 9. The system of claim 1, wherein the yeast is maintained in the mixture with a concentration of at least approximately 100,000 organisms per ml of mixture. 10. A method of stabilizing biochemical nutrients in organic material, comprising: receiving the organic material;extracting the biochemical nutrients from the organic material by comminuting the organic material in the presence of water;mixing the biochemical nutrients with yeast in a biological tank to form a mixture, the biological tank comprising a blower coupled to a bubbler, the bubbler being comprised of a tube extending vertically through the mixture and having a distal end located in proximity to the bottom of the biological tank, the tube having an opening at a distal end; andbubbling oxygen into the mixture in the biological tank by passing oxygen through the tube to exit the tube at the opening in the distal end and enter the mixture near the bottom of the biological tank, thereby maintaining the mixture in the biological tank in a non-turbulent quiescent state while providing oxygen to the mixture, and maintaining an oxygen content in the mixture at approximately 0.5-3 ppm. 11. The method of claim 10, wherein extracting the biochemical nutrients comprises forming a slurry of liquid and particles of organic material. 12. The method of claim 11, further comprising adding hydrolytic enzymes to the slurry to hydrolyze the particles of organic material. 13. The method of claim 11, further comprising heating the slurry to pasteurize harmful microorganisms in the slurry. 14. The method of claim 10, wherein the yeast is Saccharomyces cerevisiae. 15. The method of claim 10, further comprising monitoring the oxygen content of the mixture. 16. The method of claim 10, wherein comminuting the organic material comprises comminuting the organic material to a particle size of less than approximately 3 mm to extract the biochemical nutrients. 17. The method of claim 10, wherein mixing the biochemical nutrients with a yeast comprises anabolizing the biochemical nutrients to form a biomass, and wherein the percentage of biochemical nutrients that are stabilized as compared to biochemical nutrients that are anabolized is greater than approximately 85%. 18. The method of claim 10, wherein the mixture of yeast and biochemical nutrients is maintained in a stable state in aerobic conditions for at least 14 days. 19. The method of claim 10, further comprising maintaining the yeast in the mixture at a concentration of at least approximately 100,000 organisms per ml of mixture. 20. The method of claim 10, further comprising operating the biological tank at ambient temperature and ambient pressure.
