High value organic-enhanced inorganic fertilizers

A process for manufacture of a fertilizer with a predetermined content of one or more of nitrogen, phosphate and potassium comprising:

• providing an organic material containing biosolids wherein the organic material has a solids content of at least ten percent;
• adding an odor control agent to the organic material to create a mixture;
• heating the mixture under a first pressure to a first temperature for a first period of time;
• adding an amount of a predetermined acid to the heated mixture, thereby creating an exothermic reaction and forming a liquefied mixture;
• adding a predetermined amount of ammonia to the liquefied mixture under a second pressure and heating the mixture to a second temperature for second period of time, wherein the amount of ammonia added is determined from the composition of the organic material;
• and
• processing the liquefied mixture to form the fertilizer with a predetermined content of one or more of nitrogen, phosphate and potassium.

A system for the manufacture of a fertilizer comprising:

• a mixer that blends biosolids with an odor control agent;
• a first reaction or pressure vessel wherein the blended biosolids are mixed with an acid and heated to a first predetermined temperature and pressurized to a first predetermined pressure for a period of time forming a liquid;
• a second reaction or pressure vessel wherein the liquid is mixed with ammonia from an ammonia source and heated to a second predetermined temperature and pressurized to a second predetermined pressure for a second period of time;
• and
• a granulator wherein the ammoniated liquid is mixed with preformed granules and heated to form dried granules of the fertilizer.

A method for manufacture of a product comprising:

• providing an organic material wherein the organic material has a solids content of at least ten percent;
• adding an acid to the organic material under a first pressure and elevated temperature for a first period of time forming a liquefied mixture;
• adding ammonia to the liquefied mixture under a second pressure and elevated temperature for a second period of time;
• and
• processing the liquefied mixture to form the product.
