Extrusion International 3-2025

35 Extrusion International 3/2025 RECYCLING – CASE STUDY Top Performance in Plastics Recycling Cabka GmbH & Co. KG in Weira is part of the Cabka Group, which became a listed company in 2022. As a pioneer in processing mixed plastics, recycling has been part of the company’s DNA for more than 25 years. Lindner’s Micromat HP supports the innovative company in creating sustainable products and impresses with its performance. T he Cabka Group is an innovative recycling company specialised in producing pallets and large contain- ers made from recycled plastic. As a plastic recycling pioneer, the company has prioritised sustainability and the circular economy for over 25 years. At its Weira site, mixed plastics from a range of different fractions are processed on all its lines. These fractions generally include PE, PP, PS and PET as well as additional materials such as caps and labels. The plastic recycling lines run seven days a week in continuous shifts. After shredding, drying and mechani - cally cleaning, the new raw materials are transformed into the different end products at the very same site. “The choice of the right shredder plays a crucial role in the recycling process,” says Christian Leicht, Techni - cal Manager at the Weira site. “To achieve a high level of productivity, it is especially important to maintain a consistently high throughput together with minimal downtime. The Micromat HP has impressed us in many respects.” “We specifically designed the single-shaft shredder Micromat HP for the heightened demands in plastic recycling. For instance, this sector requires a greater throughput and the plastics being processed have a significantly higher level of contamination,” adds Christoph Gaschnig, Product Manager at Lindner Recy - clingtech. “This is why we’ve equipped the new Micro - mat HP with a powerful direct belt drive and an adjust- able torque. The wear parts are designed such that they can be easily replaced – the rotor is easy to access to en- sure contaminants can be removed quickly without any problem.” Leicht describes their initial reaction: “When Lindner offered us the newMicromat HP for a trial run, we were initially sceptical. However, comparative tests with the existing shredders in our plant surprised us – in a good Lindner’s new Micromat 2000 HP was showcased at K 2022 and started work at Cabka Recycling a short time later. The throughput, ease of maintenance and minimal downtime continue to prove impressive.
