Methods, systems and agglomerators for recovering mixed multi-plastic and natural fiber are described. The systems, methods, and the agglomerator operate at low temperatures to avoid degradation of the plastic film. The agglomerator includes cutting discs that are adjustable.

Systems and methods for an automated device that reduces a footprint of a bottle by moving linearly moving and rotating the bottle, while a blade cuts a body of the bottle into a continuous strip.

A method for producing filaments from polyester waste, having the steps of mechanically comminuting the polyester waste, post-condensing the comminuted polyester waste in the solid phase, melting the post-condensed polyester waste and extruding the melt in order to form filaments. Prior to carrying out the melting step for extrusion purposes, the method is completely carried out below the melting temperature of the polyester waste. The solution viscosity of the post-condensed polyester waste equals at least 1.7. Possible applications of the filaments according to the invention are, for example, reinforcement carcasses for vehicle tyres.

A method of manufacturing bulked continuous carpet filament from recycled polymer. In various embodiments, the method includes: (1) reducing recycled polymer material into polymer flakes; (2) cleansing the polymer flakes; (3) melting the flakes into a polymer melt; (4) removing water and contaminants from the polymer melt by dividing the polymer melt into a plurality of polymer streams and exposing those streams to pressures below 25 millibars or another predetermined pressure; (5) recombining the streams; and (6) using the resulting purified polymer to produce bulked continuous carpet filament.
