Extrusion International 3-2024

38 Extrusion International 3/2024 RECYCLING – CASE STUDY collected within the Loacker Group and delivered to Wonfurt for processing. The focus is on extracting pure materials to maximise the recyclables recovery. Matthias Köhler has been Managing Director at the Wonfurt site since 2012. In recent years, a great deal of energy and expertise has been invested in expand- ing the recycling plant to achieve the best possible re- cycling results using the latest technology. In a three- shift operation, up to 100 tonnes of end-of-life cables are transformed into valuable recyclable materials ev- ery day. „We mainly recover copper from old cables, around 40 to 45 tonnes a day, but also PVC and ferrous metals. While the copper is turned into copper sheets in copper smelters, we deliver the PVC to a company lo - cated on site. There, the plastics are turned into barrier products. Ferrous metals are sent for metal process- ing. The way our plant is equipped, we achieve a par - ticularly high degree of purity. That’s what makes us unique and gives us the ability to return almost 100% of the recycled material back into the cycle,“ explains Matthias Köhler. The Lindner Polaris 2800 with rotor cooling has been part of the plant at Loacker in Wonfurt since July 2023 and shreds copper cables to a final output size of <15 mm. „We are more than happy with the through- put rate and are particularly pleased that the shredder handles non-shreddables with ease, which do show up from time to time,“ says Köhler happily. In buying a Po - laris, a conscious decision was also made in favour of the screwable and quadruple-use blade cutting system. „We change the knives every seven to eight days, which is extremely easy thanks to the screwable system. It is also easy to access the rotor, knives and knife holders,“ says Matthias Köhler. „Furthermore, the Polaris 2800 has the necessary drive power. Equipped with a coun- tershaft drive and flywheel energy storage, the machine makes light work of shredding even difficult materials such as end-of-life cables with a high content of copper wire. The consistent throughput rate and high uptimes speak for themselves,“ states Jan Rosenmeyer, Sales Manager at Lindner. „We are extremely happy with the Polaris and would choose a Lindner shredder again. Output, rotor cooling and ease of maintenance convinced us. Using a Lindner, you also realise that the company has decades of expe- rience in shredding technology. The overall package is just right,“ adds Köhler. Lindner-Recyclingtech GmbH Manuel-Lindner-Str. 1, 9800 Spittal/Drau, Österreich www.lindner.com Lindner’s Polaris 2800 Is equipped with a cutting system consisting of blade knives that can be used 4 times. Knives and knife holders are easily accessible. The screwable system makes it easy to change the individual knives Since July 2023, Lindner‘s Polaris 2800 with an output of 5 tonnes per hour has been helping Loacker Recycling in Wonfurt to efficiently recycle end-of-life cables. Matthias Köhler, Managing Director of Loacker Recycling at the Wonfurt site since 2012, is more than happy with the output, maintenance and Lindner’s exceptional quality
