A process for the recovery of aluminum, or recycling process, is described, which is based on separating the aluminum contained in aseptic carton packs (1), flexible packs (2) and residual aluminum alloy powder (3) used in manufacturing additive, through the selective dissolution of aluminum in a solution known as Bayer liquor and/or caustic soda, with sodium aluminate (liquid) and hydrogen gas (H.sub.2, gaseous) products. Both products can be used in an alumina refinery, the sodium aluminate is used for the production of aluminum hydroxide and the hydrogen can be used as fuel for boilers, furnaces or similar.

Subject-matter of the present invention is a method for removing at least one polymer component from plastic waste film material, wherein the plastic waste film material comprises at least a first polymer to be solved and a second polymer component, wherein the method comprises the steps of moving said plastic film material across at least one solvent bath which is filled with a solvent, wherein said solvent is a solvent for the first polymer component to be solved, and wherein at least the second polymer component is non-soluble in said solvent.

Systems for manufacturing bulked continuous carpet filament from polymer, where the systems are configured for: (1) melting polymer (e.g., derived from post-consumer PET bottles) to create a first single stream of polymer melt; (2) separating the first single stream of polymer melt into multiple streams of polymer melt; (3) exposing the multiple streams of polymer melt to a pressure of between about 0 millibars and about 5 millibars; (4) allowing the multiple streams of polymer melt to fall into a receiving section of a melt processing unit; (5) recombining the multiple streams of polymer melt into a second single stream of polymer melt; and (6) providing the second single stream of polymer melt to one or more spinning machines that are configured to form the second single stream of polymer melt into bulked continuous carpet filament.

A method of manufacturing bulked continuous carpet filament that includes providing a polymer melt and separating the polymer melt from the extruder into at least eight streams. The multiple streams are exposed to a chamber pressure within a chamber that is below approximately 25 millibars, or another predetermined pressure. The streams are recombined into a single polymer stream. Polymer from the polymer stream is then formed into bulked continuous carpet filament.

A method for processing, and gaining value from, waste which is created by recycling paper from used beverage cartons, and a processing line for performing this method are disclosed. In Phase I, the flake size of the input material is reduced, the rough waste and dust waste removed from it, the thus treated input material is separated into fraction, containing mainly non-foil plastic, and fraction containing mainly PE foil and PE+AL foil. In Phase II, fraction containing mainly PE foil and PE+AL foil undergoes washing in a water-based formic acid solution and is separated into fraction, containing mainly polyethylene, and fraction, containing mainly aluminium. During Phase III, fraction is processed into aluminium and in Phase IV, fraction is processed into polyethylene granules, then, in Phase V, fraction has the admixture removed and is processed into regrind or granules.

A polymeric aerosol dispenser that is recyclable. The recyclable polymeric aerosol dispenser including all polymeric components. These components being selectively either fixedly joined or separably joined based on the material composition of the component. Further, components may be selected for their density and, thus, their ability to float or sink during the recycling process. The recyclable polymeric aerosol dispenser is designed to minimize its impact on the PET recycling stream and to align with industry recyclability guidelines.
