Extrusion International USA 6-2019

REVIEW 54 Extrusion International 6/2019 cycling value chain, although the material qualities of collected plas- tics from household collections are stagnating at a rather low level. In order to still be able to produce high-quality rPellets, manufactur- ers of sorting plants, washing plants and finally recycling machines are therefore even more challenged in the direction of innovation. The inline measurement of the most important plastic properties offers the rPellets manufacturer the possibility to determine the quality of the plastic melt already during the recycling process and to initi- ate appropriate sorting measures or additive feeds immediately. The automated quality recording of MFI, mechanical and optical prop- erties (colour, polymer defects) and polymer recognition create the necessary confidence in the rPellets processor and provide information on the quality level via data acqui- sition compared to the preliminary processes. The demand for larger recycling machines and automated quality records is a clear sign of increasing efficiency pressure on the recycling industry. “Thanks to the modular design of the NGR systems, we can signifi- cantly reduce development times. In this project, we were able to assemble over 80% of the system components from parts that had already been tested in other ma- chines - this is very much in line with our rapidly changing market and customer requirements,” says Thomas Pichler, Technical Director and co-owner at NGR.

The NGR C:GRAN series has been extended to machines for outputs of 2,200 kg/h and over. This expan- sion follows the market trend of increasing plastic recycling quanti- ties and modernization of recycling plants to satisfy the increased de- mand for high-quality rPellets. The rapidly increasing recycling quantities of plastics are driven by expectations and specifications from European legislation, which will continue to rise in the coming decade. However, the recycling industry is not only facing a quan- titative challenge – the quality of rPellets must also be comparable with that of virgin pellets in order to provide plastics processors with the raw material security they are already accustomed to. “NGR has a broad portfolio of re- cycling machines with very differ- ent, specialized technologies. We recommend shredder-feeder-ex- truder combinations, especially for dry industrial waste – but for high moisture mixed plastics from the post-consumer waste stream, cut- ter-compactor-extruder combina- tions offer advantages,” explains Patrick Steinwendner the strategic and technological access to the market.
