Abstract

This invention discloses systems and methods for conversion of manure to novel fertilizer and/or soil builder products useful as input for organic farming operations. The equipment systems comprise a gas turbine generator unit (preferred heat source), a dryer vessel and a processing unit, wherein the connection between the gas turbine and the dryer vessel directs substantially all the gas turbine exhaust into the dryer vessel and substantially precludes the introduction of air into the dryer vessel. The dryer vessel receives the manure for contact with the turbine exhaust gases to convert the manure to a dry material, which is passed to the processing unit where it is formed into granules, pellets or other desired form for the final dry fertilizer product. The method comprises drying, heating and converting the manure to form novel self binding fertilizer and soil builder type products for organic farming and other uses.

Claims

1-23. -23. (canceled)

24. A fertilizer material or soil builder material comprising a manure feedstock thermally treated at sufficient temperatures, without significant oxidation and for a sufficient period of time to provide a self-binding manure material suitable for forming into granules, pellets or prills suitable for conventional dry application in a crop growing operation.

25. A fertilizer material or soil builder material according to claim 24 comprising less than about 15% by weight moisture.

26. A fertilizer product or soil builder product comprising a manure feedstock thermally treated at sufficient temperatures, without significant oxidation and for a sufficient period of time to render the manure self-binding and formed into granules, pellets or prills suitable for conventional dry application in a crop growing operation.

27. An organic fertilizer material or soil builder material according to claim 26 comprising less than about 15% by weight moisture.
