A system and method for processing a supply of post-consumer scrap linear low density or low density polyethylene film into near-virgin quality blown film product. The method includes tearing the supply of film in a shredder, wherein the surface area of the film is exposed, including delaminating the film. The torn supply of film is washed in a water bath including a surfactant. The film is agitated in the bath containing the surfactant wherein contaminants on the film are removed from the film. The washed film is ground into smaller pieces and additional washing of the ground film in a rotating friction washer and a sink float tank occurs wherein additional contaminants are removed from the film. The ground film is then dried and compacted without addition of water into granulated objects of near-virgin quality blown film product.

A system for comminuting solid waste material including a shredding device disposed within the casing and comprising parallel first and second shredding stacks that include first and second parallel shafts rotatably mounted between an upper shredding device housing and a lower shredding device housing and a rotating screening drum disposed within the casing and mounted between an upper screening drum housing and a lower screening drum housing, the rotating screening drum configured to permit fluid to pass therethrough while capturing solids on an outer surface for delivery to shredding device, an upstream portion of the rotating screening drum disposed upstream of an upstream portion of the shredding device. The upper shredding device housing and the lower screening device housing are separate members from the upper screening drum housing and the lower screening drum housing to permit interchangeability of different sizes of these components to meet system needs.

A method for comminuting kitchen waste and/or food residues includes receiving kitchen waste and/or food residues in a funnel, a base of which is provided with a grinding unit for comminuting the kitchen waste and/or food residues and which is connected by the grinding unit via a product line to a pump for pumping away comminuted kitchen waste and/or food residues, and pumping away the kitchen waste and/or food residues comminuted by the grinding unit. Prior to the pumping-away step, precomminution of the kitchen waste and/or food residues located in the funnel is carried out in the funnel by means of a precomminution unit projecting into the funnel. A correspondingly designed device for implementing the method is also described.

A carpet recycling method is disclosed. In a toroidal flow pulper, pieces of carpet are disintegrated in a quantity of liquid to form a slurry of fibrous carpet materials and carpet ash. At least a portion of the fibrous carpet materials are separated from the slurry, and the separated fibrous carpet materials are dried. At least a portion of the carpet ash is isolated from the slurry, and the isolated carpet ash is dried. Thus, a first output comprising dried separated fibrous carpet materials is produced, and a second output comprising dried carpet ash is produced.

A method for milling flex foil includes providing a web of flex foil including a substrate; a first conductive layer arranged on one surface of the substrate; a second conductive layer arranged on an opposite surface of the substrate; a first insulating layer arranged adjacent to the first conductive layer; and a second insulating layer arranged adjacent to the second conductive layer. The method includes dry milling one side of the web using a first clich pattern including raised portions and non-raised portions to selectively remove at least one of the first conductive layer and the first insulating layer. The method includes dry milling an opposite side of the web using a second clich pattern including upper raised portions, lower raised portions and non-raised portions to selectively remove the second insulating layer.
