Abstract:
Die vorliegende Erfindung betrifft die Verwendung von Flüssigkristal-Displays (LCD's = Liquid Crystal Displays) sowie Verfahren zu deren Verwertung. Die erfindungsgemäßen Verfahren sind dadurch gekennzeichnet, dass die LCD's zumindest teilweise als Ersatz für andere Rohstoffe eingesetzt werden. Im allgemeinen werden die LCD's dabei in einem Temperaturbereich von 900 bis 1700°C thermisch behandelt.
Abstract:
This invention pertains to a method and apparatus for reclaiming gypsum from waste paper laminated gypsum wallboard. The invention is directed to an apparatus that is useful for separating paper laminate (14, 16) from gypsum wallboard comprising: a roller (2) and a plate spatially disposed from the roller (2). The aperture between the roller (2) and the plate is sized to be slightly less than the wallboard thickness thereby creating a fracturing action between the gypsum (18) and the paper laminate (14, 16). The first roller (2) can be driven by a power source. A roller (6) can be substituted for the plate and can be undriven or driven independently of the first roller (2).
Abstract:
A method of forming a reinforced building product from garbage, comprising the steps of sorting garbage, shredding plastics within the garbage, shredding fibers within the garbage, heating the shredded plastics, forming a slurry from the plastics and fibers, disposing the slurry within an extrusion cavity, extruding the fluid through a venturi, and allowing the extruded materials to cool. Garbage is separated into plastics, fibers, and other materials. Plastics are shredded to facilitate melting. Fibers are shredded to macroscopic lengths no greater than a maximum internal diameter of a venturi. The plastics are melted. The melted plastics are mixed with fibers and other material to form a slurry that is extruded from a cavity through a venturi, thereby causing significant alignment of the shredded fibers within the slurry in an outer region of the extruded slurry. Cooled, there is reinforced building material.
Abstract:
The use of comminuted, recycled glass powders as a filler in molded plastic parts is disclosed. The recycled glass preferably has rounded edges, which is a distinct advantage over conventional ground glass which has extremely sharp edges. Suitable comminuted glass is free from contaminants such as grinding compounds. The comminuted recycled glass filler can be used with a variety of different thermoplastics commonly used in injection molding, rotational molding, and blow molding of plastic parts.
Abstract:
A disposal method for entirely recycling solid refuse includes the following steps: sorting, crushing, drying, pressing with high pressure to shaped articles, producing charcoal from combustible refuse in high temperature and firing incombustible refuse in high temperature, at last cooling high temperature articles to obtain solid fuel with various shapes and bricks or board used for building. The method achieves entirely recycling house refuse, especial solid refuse. The method recycles solid refuse to obtain fuel and building material with economic value. The method is simple and its processing cost is low.

Abstract:
A process for activating vulcanized waste rubber particles by treating the waste rubber particles with a rubber latex and a curing system and drying the treated waste rubber particles. The waste rubber particles are preferably treated with 1 to 4 % by weight of rubber latex (calculated as dry substance) and 0.5 to 3 % by weight of sulfur as vulcanizing agent, both being calculated on the waste rubber particles. The treatment is carried out conveniently by mixing the waste rubber particles with the vulcanizing agent, adding the latex at a temperature of from 70 to 90 DEG C and stirring the obtained mixture for 5 to 10 min. so as to evaporate the water. Also disclosed are processes for producing a rubber-like article by molding the activated waste rubber particles, whether or not mixed with a non-vulcanized rubber compound, while applying heat and pressure.
