Starlinger & Co. GmbH has introduced its recycling plant in a single machine, the Recostar 45 Compact, especially suited to recycling plastic films from rolls and film edge trims, or small injection molded parts.
Material is fed into the grinder using an edge trim cyclone or a reel feeder. The grinder cuts the material and feeds it directly into the extruder. The Recostar Compact, exhibited at NPE 2006, held June 19-23 in Chicago, uses discontinuous manual screen changers for most material, but the firm also offers continuous filters and safety filters.
Starlinger of Vienna, Austria, said a big advantage of the machine is that there is no preheating before extrusion. It can be fully integrated into a film line.
During NPE, Starlinger ran a Recostar 65 Universal at an open house held at its plant in the Chicago suburb of Hanover Park, Ill. The line is designed for processing hard-to-cut waste such as tapes, fibers, lumps, injection molded items, dry films and fleece. A single-shaft cutter is mounted parallel to the extruder, and both are driven independently.
The company also has a new line of Viscostar reactors to crystallize pre-washed, recycled PET flakes and convert them into food-grade pellets. The system pairs Starlinger's Recostar PET recycling machine with a Viscotec Solid State Polycondensation unit.
