Abstract

Abstract The method of this invention comprises the steps of sorting processable and nonpocessable materials from waste materials, sorting ferrous materials from processable materials, shredding processable materials, evaporating and dehydrating processable materials at substantially high temperatures while avoiding burning or incineration of the materials, and pulverizing or grinding the materials into a spreadable grain-size fertilizer and soil conditioner product. The apparatus includes a primary sorting table, a magnetic sorting means for ferrous materials, a material shredder, a substantially high-temperature, enclosed, controlled atmosphere evaporator-dehydrator, and a mixergrinder.
