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 method of processing municipal solid waste includes extracting food waste, inert materials, and ferrous and non-ferrous metals from the municipal solid waste, shredding the municipal solid waste and thereby generating a product feed comprising at least 99.7% by volume cellulose-based materials and plastic. The product feed is conveyed to a forming system and a manufacturing product is created out of the product feed with the forming system.

Solid waste that includes a mixture of wet organic material and dry organic material can be are separated using mechanical separation to produce a wet organic stream enriched in wet organics and a dry organic stream enriched in dry organics. The separated wet organic stream and dry organic stream are separately converted to renewable or recyclable products using different conversion techniques particularly suited for the separated wet and dry organic streams.

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 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 5 millibars. The streams are recombined into a single polymer stream and formed into bulked continuous carpet filament.

A method includes producing recycled products from a plurality of used absorbent articles, each including a top sheet, a back sheet and an absorbent body including absorbent body materials, by recovering a plurality of structural members from the plurality of used absorbent articles. At least one of the top sheet and the back sheet includes a film. The method includes: separating the plurality of used absorbent articles into a plurality of the films and the absorbent body materials; sorting the plurality of films into a plurality of types of recyclable films according to the filler contents of the plurality of films; and forming a plurality of types of recycled resin pellets from the plurality of types of recyclable films.

A modular system and process are described for recycling textile waste of various compositions into new ready to use fibers for garment manufacturing or other uses.

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 system for manufacturing bulked continuous carpet filament that is adapted for providing a polymer melt and dividing the polymer melt into a plurality of streams (e.g., at least six or eight streams) to increase a surface area of the polymer melt. The plurality of streams is then exposed to a pressure that is below approximately 5 millibars. The streams are then recombined into a single polymer stream and formed into bulked continuous carpet filament. In various embodiments, an extruder, such as a multi-screw extruder, is used to divide the polymer melt into the plurality of streams.
