Abstract

A system and method of forming high nutritional fertilizer form swine feces in a reservoir underneath a swine facility. A pump system has a pump that conveys the feces to a remote location where the swine feces first goes through a filter and then into a treatment tank. The treatment tank has sugars or carbohydrates therein that combine with oxygen provided by a aerating device within the treatment tank and ammonia produced by the swine feces to create byproducts, including proteins having high nutritional value that is used for fertilizing plants and animals.

Claims (14)

1. A method of forming high nutritional fertilizer steps comprising:

providing an aerating device within a reservoir of containing swine feces;

directing oxygen into the feces with the aerating device;

adding a sugar into the feces simultaneously with the oxygen to convert ammonia into proteins to be used as high nutritional fertilizer.

2. The method of claim 1 wherein the sugar is fructose.

3. The method of claim 1 wherein the sugar is glucose.

4. The method of claim 1 wherein the sugar is molasses.

5. The method of claim 1 wherein the sugar has a chemical composition of C12H22O11.
