摘要:
The invention relates to a method for separating a waste material including plastic material and metallic material. The method includes the steps: shredding and/or granulating the waste material including plastic and metallic material; mixing and wetting the granulated waste material with process-water; subjecting the granulated waste material to a sink-float process separating the mixture into two fractions having different average densities, the fraction with the lowest average density being designated the light fraction and the other fraction being designated the heavy fraction, removing the light fraction; and subjecting the heavy fraction to treatment on a shaking table separating the heavy fraction into a metallic fraction and a heavy plastic fraction; optionally subjecting the heavy plastic fraction to a second sink-float process.

Systems and methods for providing a quantity of cullet having at least two colors of glass from an input stream of recyclable material and non-recyclable material. In an embodiment, the system includes a sortation station, a screening apparatus, an air classifier, and a crushing apparatus to provide as output substantially pure cullet having at least two colors.

Systems and methods for collecting data pertaining to glass, plastic and/or paper composition within an input stream that includes recyclable material. The data collected can pertain, for example, to the weight and/or volume of the glass, plastic and/or paper within the input stream. The data can be certified for use a third party.
摘要:
A method for waste plastics disposal which comprises immersing inorganic materials-containing waste plastics which contains metals, fibers, wood, glass, halogenated hydrocarbons and the like originating from waste automobiles, electrical home appliances and the like in an organic medium which has a boiling point higher than 400 °C and an aromatic index of 0.2 or more, and has been heated to 200-400 °C or that which has a boiling point of 300 to 400 °C and an aromatic index of 0.2 or more, and has been heated to a temperature of from 200 °C to the boiling point thereof, for example, a coal tar heavy oil, a pitch, a coal liquid, a bottom residue in an ethylene plant and an FCC oil which have been heated as described above. The method allows efficient separation and recovery of a mixture of plastics and inorganic materials, resulting in material recycle.

Procédé de recyclage d'un mélange non trié de piles boutons usagées et récupération de leurs composants métalliques comprenant une dissolution anodique des piles boutons, au cours de laquelle les métaux constituant ces piles sont dissous et redéposés sur une ou plusieurs cathodes, les oxydes métalliques se déposent dans le compartiment anodique et les déchets (plastique, papier, etc.) s'accumulent dans un panier anodique. Les oxydes sont réduits en métaux par décomposition thermique, le mercure est récupéré par distillation et les autres métaux sont récupérés par séparation électrolytique.
摘要:
The invention provides a self-supporting flame resistant composite material comprising at least one layer (1) of lead material and at least one layer (2) of flame resistant fibrous material, the layers (1,2) having been bonded together, e.g., mechanically as by needling, to provide a self-supporting structure.
