NOVELTY - Receiving animal waste from animal confinements and other concentrated animal waste resources and converting waste into usable form, the waste containing liquids and solids, comprises separating liquids and solids into separate waste streams; and controlling an amount of moisture in solids waste stream such that amount of moisture in solid waste stream is compatible with selected energy conversion process.    USE - For receiving animal waste from animal confinements and other concentrated animal waste resources and converting waste into usable form, e.g. fuel for heat, transportation or direct conversion to power by engine or combustion turbine.    ADVANTAGE - The method does not contribute to odor released into the atmosphere, providing a more desirable approach to the problem of animal production waste.    DETAILED DESCRIPTION - Receiving animal waste from animal confinements and other concentrated animal waste resources and converting waste into usable form, the waste containing liquids and solids, comprises separating liquids and solids into separate waste streams; controlling an amount of moisture in solids waste stream such that amount of moisture in solid waste stream is compatible with selected energy conversion process; and feeding moisture controlled solid waste into the energy conversion process. An INDEPENDENT CLAIM is also included for a system for processing a waste stream from animal production confinements and other sources of concentrated wastes, comprising solids/liquids separator receiving the waste stream and separating into solid and liquid waste streams; water treatment apparatus for treating the liquid waste stream; control system for selectively controlling an amount of moisture in the solid waste stream; energy conversion processor receiving the moisture controlled solid waste stream and converting the solid waste stream into energy source; and power generator configured to utilize the energy source.    DESCRIPTION OF DRAWING(S) - The figure is an overall conversion process diagram of a system for converting a waste stream into a fuel source, including a solids/liquids separator.
