Integrated waste treatment and fertilizer and feed supplement production methods to be implemented at organic waste source sites, at remote treatment sites, or partially at the organic waste source site and at a remote location, whether in small or large scale operations. The methods are suitable for retrofitting existing organic waste sources and for treating the organic waste generated by a single source or by a plurality of sources. These methods provide: reduction or elimination of emissions of acrid and greenhouse gases; effluents that meet discharge standards and that can be used in wetland and irrigation projects; organic based, granular, slow release NPK fertilizer of standard composition and size that can be supplemented with micronutrients and soil amendment materials and whose composition can be adjusted to meet demands and needs of specific markets; methane-rich biogas recovery for its subsequent use for heating, for power generation or for catalytic and synthetic processes, and feed supplement including feed supplement for cattle. The methods comprise steps for thoroughly separating suspended and dissolved materials, preventing gas emissions and capturing gases, and minimizing waste disposal. Fertilizer base may be produced by mixing waste with at least one of a phosphate precipitating agent, a base, a flocculant, and optionally with an ammonia retaining agent and a densifier, subsequently separating and drying the precipitate. Pathogen-free, odor-free and dust-free fertilizer may be obtained by temperature controlled incineration or combustion.

1. A fertilizer derived from animal wastes, comprising:a dust-free, odor-free, and pathogen-free material, derived from animal wastes, that has a nitrogen content of at least about 5% expressed as N, a phosphorous content of at least about 5% expressed as P2O5, and a potassium content of at least ab
1. A fertilizer derived from animal wastes, comprising:a dust-free, odor-free, and pathogen-free material, derived from animal wastes, that has a nitrogen content of at least about 5% expressed as N, a phosphorous content of at least about 5% expressed as P2O5, and a potassium content of at least about 5% expressed as K2O, wherein said material is devoid of compounds that would decompose or ignite at a temperature below about 300° F. 2. A fertilizer as recited in claim 1, wherein at least one of said nitrogen content, phosphorous content, or potassium content is at least about 10%.3. A fertilizer as recited in claim 1, wherein at least one of said nitrogen content, phosphorous content or potassium content is at least about 12%.4. A fertilizer as recited in claim 1, wherein said material has a nitrogen content of at least about 10% expressed as N, a phosphorous content of at least about 10% expressed as P2O5, and a potassium content of at least about 10% expressed as K2O.5. A fertilizer as recited in claim 1, wherein said material is in the form of pellets.6. A fertilizer as recited in claim 5, wherein said pellets have a friability that does not exceed about 5%.7. A fertilizer as recited in claim 5, wherein said pellets have a friability that does not exceed about 2%.8. A fertilizer as recited in claim 5, wherein said pellets have a friability that does not exceed about 1%.9. A fertilizer as recited in claim 1, wherein said material further comprises at least one of a calcium-based nutrient, a magnesium-based nutrient, or a sulfur-based nutrient.10. A fertilizer as recited in claim 1, wherein said material further comprises at least one of an iron-based micronutrient, a manganese-based micronutrient, a copper-based micronutrient, a zinc-based micronutrient, a boron-based micronutrient, or a molybdenum-based micronutrient.11. A fertilizer as recited in claim 1, wherein said material is derived from hog wastes.12. A fertilizer as recited in claim 1, wherein said material is derived from cattle wastes.13. A fertilizer as recited in claim 1, wherein said material is derived from chicken wastes.14. A fertilizer derived from hog wastes, comprising:a dust-free, odor-free, and pathogen-free material, derived from hog wastes, that has a nitrogen content of at least about 10% expressed as N, a phosphorous content of at least about 5% expressed as P2O5, and a potassium content of at least about 5% expressed as K2O, wherein said material is devoid of compounds that would decompose or ignite at a temperature below about 300° F. 15. A fertilizer as recited in claim 14, wherein said material is in the form of pellets.16. A method of manufacturing a fertilizer, comprising:obtaining a non-pathogen-free fertilizer product derived from animal wastes and in pellet form; initiating combustion in said fertilizer product by heating said fertilizer product at a temperature that does not exceed about 540° F.; allowing partial combustion of said fertilizer product, while said fertilizer product remains in pellet form, so that said fertilizer product is rendered pathogen-free; and quenching the combustion of said fertilizer product in pellet form. 17. A method of manufacturing fertilizers as recited in claim 16, wherein said fertilizer product in pellet form has a nitrogen content of at least about 5% expressed as N, a phosphorous content of at least about 5% expressed as P2O5, and a potassium content of at least about 5% expressed as K2O, wherein said material is devoid of compounds that would decompose or ignite at a temperature below about 300° F.18. A method of manufacturing a fertilizer as recited in claim 16, further comprising cooling said fertilizer product after said quenching.19. A method of manufacturing a fertilizer as recited in claim 16, wherein said temperature is in the range from about 290° F. to about 450° F.20. A method of manufacturing a fertilizer as recited in claim 16, wherein said temperature is in the range from about 300° F. to about 400° F.21. A method of manufacturing a fertilizer as recited in claim 16, wherein said temperature is in the range from about 320° F. to about 350° F.22. A method of manufacturing a fertilizer as recited in claim 16, wherein said obtaining a non-pathogen-free fertilizer product in pellet form comprises obtaining wet animal waste solids, agglomerating said wet solids, and drying said wet solids to form pellets.23. A method of manufacturing a fertilizer as recited in claim 16, wherein said combustion of said fertilizer product comprises reducing the mass of said fertilizer in an amount that is in the range from about 20% to about 70% of the dry mass of said non-pathogen-free fertilizer product.24. A method of manufacturing a fertilizer as recited in claim 16, wherein said heating said fertilizer product at a temperature that does not exceed about 540° F. is performed by exposing said fertilizer product to flameless combustion products.25. A method of manufacturing a fertilizer as recited in claim 16, wherein said fertilizer product is derived from hog wastes.26. A method of manufacturing a fertilizer as recited in claim 16, wherein said fertilizer product is derived from cattle wastes.27. A method of manufacturing a fertilizer as recited in claim 16, wherein said fertilizer product is derived from chicken wastes.28. A method of manufacturing a fertilizer, comprising:obtaining a non-pathogen-free fertilizer product derived from hog wastes and in pellet form; initiating combustion in said fertilizer products by heating said fertilizer product at a temperature that does not exceed about 500° F.; allowing partial combustion of said fertilizer products, while said fertilizer product remains in pellet form, so that said fertilizer product is rendered pathogen-free; and quenching the combustion of said fertilizer product in pellet form, said fertilizer product having a nitrogen content of at least about 5% expressed as N, a phosphorous content of at least about 5% expressed as P2O5, and a potassium content of at least about 5% expressed as K2O, wherein said material is devoid of compounds that would decompose or ignite at a temperature below about 300° F.
