摘要： A system comprising: (1) a grinding unit configured to receive and grind recycled PET bottles into a group of polymer flakes comprising up to about ten percent colored polymer flakes and balance substantially clear polymer flakes; (2) a washing unit configured to wash the group of polymer flakes; and (3) an extruder configured to extrude material in a plurality of different extrusion streams. The extruder may be further configured to: (1) receive a concentrate-polymer mixture comprising a mixture of the polymer flakes and a color concentrate; (2) melt the concentrate-polymer mixture to produce a polymer melt; (3) reduce a pressure within the extruder; and (4) pass the polymer melt through the extruder so that the polymer melt is divided into the plurality of extrusion streams. The system may then filter the polymer melt through at least one filter and form the polymer melt into bulked continuous carpet filament.

摘要： A method for recycling powdered paint waste is provided in which, the powdered paint waste is being treated with the aid of a reactant in such a way that its adhesion to surfaces and especially to metal surfaces is reduced or eliminated. The treatment of the powdered paint waste allows the powdered paint waste to be additionally processed under the influence of heat and to use it as a starting material in various recycling processes or in other processes.

摘要： A color 3D printer and its method of use are disclosed. The color 3D printer uses a number of chambers to dye a filament to a given color. This colored filament is then extruded, pursuant to an associated 3D model of an object, to produce varying colored physical objects, on demand, with the use of a single filament and a single print head. Further, the color 3D printer features a waste management apparatus which provides a number of ways to dispose of waste fluid.

摘要： A method of manufacturing a film includes forming a blend containing a renewable content starch, a renewable content mineral, and polyethylene, operating a mass flow hopper to maintain a consistent mass flow rate of the blend to a feed throat of an extruder, and operating the extruder with a screw speed and melt temperature based on the amount by weight of the starch and mineral within the blend. The melt is passed through a screen pack with a mesh rating based on the amount by weight of the starch and mineral within the blend, is passed through a die, and is cooled into a film. The film is nipped to a gauge such that the film can be formed into a bag.
