ABSTRACT:
Solid animal excreta, such as solid livestock excreta, solid human excreta and solid poultry excreta, is converted to useful products by particulating the excreta and heat treating it in a closed heating zone at about 200.degree.C to about 1000.degree.C for a time sufficient to volatilize a portion thereof and provide the solid residue with a carbon content of about 1% to about 80 weight percent. The volatilized portion can be withdrawn from the heating zone and separately recovered by condensing the condensibles. This consists of an aqueous and a non-aqueous portion. The non-aqueous portion of the condensate is oleaginous in the form of an oil, grease or wax containing nitrogenous substances and is useful for a variety of purposes. The aqueous portion is rich in nitrogen and is useful as a fertilizer. The solid particulate residue can be employed as a foaming agent or filler for glass products and as a coloring agent or pigment in inks, paints and rubber products.
