Polyamide Scrap Recovery Service
The treatment considered in this EPD is commonly applied to polyamide 6 and 66 scraps and consists of both pretreatment – cutting and/or grinding – and a final extrusion process that outputs a product in granular form, also called “cips”, suitable for use in compounding.
Grinding, outsourced to authorized companies, is often the only process performed on the material, which then ceases to be legally considered “waste” and becomes commercially available as secondary material, although still needing to undergo extrusion for its complete recovery and reuse as a fi nal product. In this physical form (small irregular flakes of various sizes), the material may not be suitable for processing in all types of extrusion plants. Indeed, the technological characteristics of extruders do not always allow them to process materials having irregular or not perfectly homogeneous sizes and shapes.
Not only does the Radici Novacips plant at Chignolo d’Isola have the right extrusion technology, but it can also perform further processing. The plant can complete the recovery process and produce secondary raw material suitable for use as a replacement of primary polymer for the production of engineering plastics. Recovery extrusion and production compounding can also occur at the same time.
The Radici Novacips case, as described above, is typical and unique at the same time. Typical, because it uses mechanical treatment, which is the most widespread method in the fi eld of plastics recovery, and, unique, because Radici Novacips’ experience, expertise and production chain synergies allow for running its recovery operations and production process even simultaneously (as described in EPD No. S-P-00707).
