Converting Manure, Food Wastes and Agricultural Production Wastes into Bio-Secure Fertilizer, feed, and/or beeding


To find a way to completely eliminate bio-hazards in manure, food wastes, municipal sludge, and agricultural production wastes.

What did we do? 

We adapted existing dry extrusion technology to bio-hazard agricultural wastes. To test the hypothesis we developed [ Dry Extrusion Technology can be adapted to convert bio-degradable hazardous wastes into Bio-Secure class “A” fertilizer, feed, and/or bedding more economically, with less environmental impact, greater sustainability, and in less time with a smaller foot print]

Once we proved our Hypothesis we further developed the process to allow the technology to be utilized in a large stationary plant suitable for a large waste generator and in a portable plant that can be used to assist smaller waste generators, such as, most agricultural producers and smaller municipalities.

What have we learned? 

Our tests showed that we could validate our hypothesis by:

1) utilizing finely ground dry agricultural production wastes, mixed with the wet food and manure to reduce the moisture content of the wet wastes to a level compatible to the requirements of the dry extruder,
2) The Dry extruder effectively sterilized the wastes by high temperature, high pressure inside the extruder, and sudden drop in atmospheric pressure inside the cell walls of all the materials when exiting the Dry Extruder, thereby destroying the cell walls of not only the bio-mass materials but also of all micro organisms ova, and pathogens inside the final product.

Future Plans 

Develop new niche markets for agricultural waste generators by adding additional value to their wastes.
