Extruded plastic profiles with integrated insulation, the method for extruding such products, and the windows and doors made with such plastic extrusions. The plastic extrusions may additionally include a low heat build-up capstock system comprising an acrylic cap and pigment system that is substantially IR transparent. The extruded plastic profiles with integrated insulation are recyclable using conventional plastic extrusion process and are fully weldable in conventional window and door manufacturing.

A container is formed to include and interior region and a mouth opening into the interior region. The container includes a floor, a side wall coupled to the floor to define the interior region between the floor and the side wall, and artwork on the side wall.

An extruder is disclosed, and more particularly, to an integrated single screw extruder and a twin screw extruder for mixing, compounding, kneading and/or extruding of materials. The integrated extruder includes a first barrel assembly and a second barrel assembly. The integrated extruder further includes a first screw having a first threaded portion and a second threaded portion. The first threaded portion is housed within the first barrel assembly and is configured to provide upstream material processing. The second threaded portion is housed within the second barrel assembly and is configured to provide downstream material processing. The integrated extruder further includes a second screw having a non-threaded shaft portion and a threaded portion. The threaded portion of the second screw is housed within the second barrel assembly and is configured to provide the downstream material processing with the second threaded portion of the first screw.

Disclosed is a system for pelletizing Solid Refuse Fuel (SRF). The system includes: a first crusher that primarily crushes plastic waste; a vibration sieve plate-conveyer that transports plastic waste that is primarily crushed by the first crusher; a second crusher that secondarily crushes the primarily crushed plastic waste sieved by the vibration sieve plate-conveyer; a first rotational shaft equipped with a first screw that fuses and transports the plastic waste which is secondarily crushed by the second crusher; a filter unit that is combined with the first rotational shaft and which removes impurities by filtering the secondarily crushed plastic waste that is fused and transported by the first screw; a second rotational shaft equipped with a second screw that transports impurity-free plastic waste filtered by the filter unit; and a molding machine that molds the plastic waste transported by the second screw.

A container is formed to include and interior region and a mouth opening into the interior region. The container includes a floor, a side wall coupled to the floor to define the interior region between the floor and the side wall, and artwork on the side wall.

A method of recycling PET into PET nurdles, 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 18 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 PET nurdles. In various embodiments, the polymer melt is formed into PET nurdles using any suitable technique such as, for example, any suitable strand pelletizing or melt pelletizing techniques.
