ABSTRACT:
A system for treating household municipal wastes, and recovering recyclable materials from the waste stream. The process includes feeding the substantially solid waste stream, comprising generally paper or pulp material, glass, metal, plastics, and other solid wastes, into a first vessel, containing heated water; rotating the vessel to intermix the solid wastes with the water under a predetermined pressure; subjecting the vessel containing the wetted materials to a vacuum so as to achieve a desired moisture content to the pulp materials preferably between 20 to 30%; conveying the materials from the vessel to be separated into component parts; providing a second treatment vessel for receiving the material in alternate use; cycling the water from the first vessel into the second vessel so that the water in the system is in a closed loop system; and routing the removed pulp material containing 20 to 25% moisture for further use or disposal.
