The invention relates to a method for the dry separation of unsorted garbage that contains packaging waste, said packaging waste including plastics of various polymer groups. The inventive method comprises the following steps: separating the materials on the basis of differences in size; separating the materials on the basis of differences in grain shape, grain size and/or specific weight; separating the materials on the basis of differences in their magnetic properties; separating the materials on the basis of differences in their electric properties; and separating the materials on the basis of differences in their spectroscopic properties. Every separation step is carried out at least once and the separation of components of the unsorted garbage results in a remaining mass flow that contains non-recyclable remaining garbage and plastic articles. The plastic articles are collectively removed from the mass flow as a mixed plastic fraction and said mixed plastic fraction is selectively separated into substantially polymer-specific fractions using polymer-specific separation methods. The invention also relates to a device for carrying out the inventive method.

The invention relates to a device and a method for blowing out metal fractions from a stream of bulk material that is conveyed by bulk material conveying means (10). The device comprises blow-out nozzles (20) which are located on a drop section and which are arranged along a widthwise extension of the stream of bulk material, for blowing against individual particles of bulk material in order to modify the trajectory in such a way as to produce a second sub-stream that branches off. The blow-out nozzles (20) can be controlled according to the sensor coil scanning results relating to the bulk material particles. A plurality of sensor coils (18) is provided underneath an essentially horizontal section of the stream of bulk material in the form of an LC oscillating circuit. Said sensor coils are provided for detecting the eddy currents that are induced. Optoelectronic means (14) are also provided for determining the blow-out position and for determining the location of each of the particles of bulk material.

A recycling system is proposed which can retrieve reusable articles at a low cost. For example, a maker of welding wires ship the wires to a user with the wires wound on bobbins. The user sends a request for taking back empty bobbins to a center after consuming the welding wires. The center notifies a forwarder of a request for retrieval. The forwarder retrieves the empty bobbins from the user and bring them to a recycler. When the maker gives an order for empty bobbins to the center, the center notifies this to the recycler and the recycler ships the recycled bobbins to the maker.

There is provided a method for recycling synthetic wood materials, transformed into materials through a relatively simple method without performing elimination of encrusted concrete from a previously used sheathing board for use in a concrete form having synthetic wood materials as raw materials. The method consists of a step wherein a sheathing board 1 (1a) which had been previously used as a concrete form 50 and formed from synthetic wood materials with a moisture content of less than 15 wt %, wherein between 20 and 75 wt % of cellulose crushed materials, such as wood meal with particle diameters of between 50 and 200 µm, and between 25 and 80 wt % of thermoplastic resin molding materials, are mixed, is crushed into numerous coated particles 82, and a step wherein a scraping impact force is applied to each individual coated particle 82, concrete and other encrusted materials encrusted on the previously mentioned coated particles 82 are peeled or separated, and at the same time as the synthetic wood materials constituting the coated particles 82 and the encrusted materials are classified, the particles of the synthetic wood materials are granulated, and the granulated synthetic wood meal materials 83 for which the particles have been granulated are recycled.

Die Zerkleinerungseinrichtung dient in erster Linie dem Recycling von Kühlgeräten. Zu der Aufbereitungseinrichtung gehört eine Zerkleinerungseinrichtung und eine Ausgaseinrichtung. Letztere dient dazu, von der Zerkleinerungseinrichtung abgegebenes Materialgemisch unter inerten Bedingungen abzukühlen, so dass das abgegebene Material zunächst nicht weiter ausgast. Auf diese Weise werden in den angeschlossenen Prozessstufen ungewollte Verluste flüchtiger Substanzen vermieden. Sowohl die Zerkleinerungseinrichtung als auch die Ausgaseinrichtung einschl. Kühlfördereinrichtung sind an eine Auffangeinrichtung für die flüchtige Substanz angeschlossen. Durch die Inertisierung einer Abkühlstrecke, auf der das durch die Zerkleinerung und/oder nachfolgende Beheizung erwärmte Material unter inerten Bedingungen abkühlt, werden Verluste oder ungewollter Austritt von flüchtigen Substanzen aus dem System vermieden.

The invention concerns a method for selectively separating predetermined materials contained in mixtures of materials, in particular mixtures formed by waste and containing other materials with characteristics similar to said predetermined materials. The method is characterised in that the mixtures of materials are subjected, according to a known operation, to at least a process of automatic separation by density, the materials whereof the mass density is within a first range of values being separated from those within a second range of values. Before or while they are being treated, the predetermined materials are enriched with at least an additive providing them a with mass density within the first range of values. Said method enables simple and economical separation for example of high value or biodegradable synthetic materials contained in waste mixtures, such that they can be subsequently treated in accordance with prescribed rules or upgraded during removal.

A system for recycling reusable resin mold products recovered from discarded apparatuses is disclosed. This recycling system includes a crushing system for crushing resin mold products one kind by one kind into crushed resinous pieces and packing the same in a bag, a classification system for irradiating a light beam to the resin in the bag and classifying the bags into respective kinds of resins based on a reflected beam therefrom, a cleaning system for separately cleaning the respective kind of crushed resinous pieces taken out of the bag to remove foreign matters adhered onto the surfaces of the crushed resinous pieces therefrom, and a recovery system for recovering the cleaned crushed resinous pieces.

Die Erfindung betrifft ein Verfahren zum Sortieren einer Kunststofffraktion innerhalb einer Abfallsortieranlage, bei der das technische Problem, eine im wesentlichen aus einer Kunststoffart bestehenden Kunststofffraktion bezüglich höherwertiger Anteile besser aufzubereiten, dadurch gelöst ist, daß mindestens eine im wesentlichen aus einer Kunststoffart bestehenden Kunststofffraktion aus einem Ausgangabfallgemisch aussortiert wird und daß die Kunststofffraktion mit Hilfe eines Ballistikseparators (26) in eine im wesentlichen harte Kunststoffobjekte aufweisende Hartfraktion und eine im wesentlichen weiche Kunststoffobjekte aufweisende Weichfraktion getrennt wird. Die Erfindung betrifft auch eine Abfallsortieranlage mit mindestens einer Sortierungseinrichtung zum Erzeugen einer Kunststofffraktion, mit Transportmitteln und mit einem Ballistikseparator (26) zum Abtrennen einer harten und weichen Fraktion.
