44 Extrusion International 3/2023 RECYCLING – CASE STUDY „Got It Covered“ Any manufacturing and production process will no doubt produce waste in some form. So does Plastipack Limited in the UK, a producer of high-quality plastic swimming pool covers and water storage systems. By the help of a WEIMA two-stage size reduction system, plastic scrap is recycled directly on-site – for a closed loop. I t all started with an inquiry to the British WEIMA dealer Fer- cell from Aylesford in the county of Kent. Plastipack has already had positive experience with re- cycling its own production waste for many years. In addition, there is an increased demand for pool foils. Consequently, the exist- ing pelletizing system was to be renewed in order to further in- crease efficiency and throughput. After extensive material testing at Fercell's test center, the opti- mum configuration was finally worked out, with Plastipack opt- ing for a two-stage processing solution consisting of a pre- and post-shredder including conveyor technology.
