Patent ID: 7776243

Claim:
A method of forming a reinforced building product from garbage, comprising the steps of: sorting the garbage by separating the garbage into plastics, fibers, and other materials; shredding the plastics to a size configured to facilitate melting; shredding the fibers to macroscopic lengths no greater than a maximum internal diameter of a venturi; providing sand-sized filler particles; heating the plastics to a temperature sufficient to substantially melt the plastic; forming a slurry by mixing the heated plastic, the filler and the fibers; disposing the slurry within an extrusion cavity, wherein the extrusion cavity includes an extrusion piston and the venturi; extruding the slurry through the venturi by actuating the extrusion piston, thereby causing significant alignment of the shredded fibers within the slurry in an outer region of the extruded slurry; and allowing the extruded slurry to cool and harden, thereby forming the reinforced building product material; and further comprising sanitizing the fibers, wherein the sand-sized filler particles are selected from the group of fillers consisting of sand, rock, and cement and wherein the fibers comprise metal wires.
