Abstract:
A process for recovering protein from animal manure for use as a sterilized animal feed which comprises the steps of:collecting the animal manure and forming an aqueous manure slurry therefrom; subjecting the manure slurry to anaerobic fermentation as an aqueous slurry at a temperature of from about 35Â° C. to about 65Â° C. for a sufficient length of time to cause a biogas to be produced from the slurry to yield a biogas stream and a feed compost slurry; sterilizing the feed compost slurry by exposing it to radio waves of sufficient intensity and for sufficient time to kill pathogens in the compost and render a feed compost safe for consumption by animals as a source of protein; drying the sterilized feed compost; and recovering the sterilized animal feed compost for use.
