A method of manufacturing bulked continuous carpet filament which, in various embodiments, comprises: (A) grinding recycled PET bottles into a group of flakes; (B) washing the flakes; (C) identifying and removing impurities, including impure flakes, from the group of flakes; (D) passing the group of flakes through an MRS extruder while maintaining the pressure within the MRS portion of the MRS extruder below about 1.5 millibars; (E) passing the resulting polymer melt through at least one filter having a micron rating of less than about 50 microns; and (F) forming the recycled polymer into bulked continuous carpet filament that consists essentially of recycled PET.

A system and method for post-processing of polymeric items having a liquid component and a predetermined heat deflection temperature is provided. The system includes a washing station to spray water at elevated temperature and pressure on the items while maintaining the temperature of the item below the heat deflection temperature. Then using a water distillation system to separate the water from the water mixed with the liquid polymer component by evaporating the water using heating coils with surface that is not conducive to adhesion of the liquid polymer component and then condense the water vapor into liquid water. The system may further include a spin station to separate the liquid polymer component by spinning the item. The system may further include one or more processing stations to rinse the item, dry the item, cure the item, remove the item from a tray to which the item may be attached and clean trays after removing the item. A conveyor system may be used to automate the post-processing of the items.

In a method for reprocessing film waste material, the film waste material is comminuted into recycling material by means of a comminuting device. The recycling material is fed by means of a feeding device in a multi-shaft screw machine. In the multi-shaft screw machine, the recycling material is plasticized into a material melt and processed into raw material. The raw material may again be fed to a production installation for the production of films.

A method and a device for removing a coating on a coated plastic article allow highly efficient removal of a coating from a coated plastic article and recovery of a base after coating removal and a remover. A method for removing a coating on a coated plastic article with a remover includes shredding the article into pieces, immersing the pieces in the remover heated to a second temperature, heating the remover to a first temperature, and stirring the pieces with the heated remover. The remover includes at least one monohydric lower alcohol selected from methanol, ethanol, propanol, and 1-butanol, and swells the base, the coating, or both. The first temperature is not lower than 25° C. and not higher than a temperature 10° C. lower than a boiling point of the remover. The second temperature is not higher than an upper limit of the first temperature.
