Copolon Debuts at K 2025: Innovative Synergy in Plastic Recycling Technology

Coperion will jointly exhibit with Herbold Meckesheim at the K Trade Fair to be held in Düsseldorf, Germany, from October 8 to 15, 2025. At booth 9B34 in Hall 9, the focus will be on showcasing Herbold Meckesheim’s mechanical processing technologies for plastic waste, including the new T 150-300 mechanical dryer and the SMS 80-200 granulator. In the open-air area FG/CE07, visitors can witness the seamless collaboration of Coperion’s full range of recycling technologies, with exhibits including:

• Herbold Meckesheim Hydraulic Cyclone Classifier
• ZSK FilCo Filter Mixing Extruder
• ZS-B MEGAfeed Side Feeder
• Kobelco Kaichuang K3-V200 Vibrating Feeder
• S60 Single Screw Feeder
• MechaTron® Flat Bottom Feeder
• Mobile Deodorization Device (for Removing Odors from Recycled Materials)

In addition, Copelon will showcase its core capabilities in plastic compounding technology at Booth 14B19 in Hall 14.

The open exhibition area FG/CE07 will demonstrate the new ZSK FilCo filter-compounding extruder, which can complete the recycling material filtration and compounding in one step. Compared to traditional two-step production lines, the ZSK FilCo handles materials more gently and significantly reduces energy consumption while improving product quality when recycling post-consumer waste plastics and other highly contaminated polymers. Waste plastics (such as recycled pellets, fiber scraps, film fragments, or untreated agglomerates) are melted, homogenized, and degassed through the ZSK twin-screw extruder. After impurities are removed by a screen, additives are injected before granulation.

To fully leverage the performance of ZSK FilCo, a stable supply of raw materials without feeding restrictions is required. Traditional granulation or compaction processes have high energy consumption and increase costs, whereas the showcased ZS-B MEGAfeed side feeder can reliably convey lightweight materials with bulk densities as low as 20 kg/m³ (such as fibers and flakes), enabling high-throughput recycling.

Coperion's high-precision feeding technology representative exhibits include:

• PK3-V200 Vibratory Feeder: Suitable for precise metering and feeding of challenging materials such as small granules or flakes.
• Mecha Tron FB flat-bottom feeder: specially designed for lightweight and difficult-to-feed materials such as polypropylene/PET films.
• S60 Single Screw Feeder: Renowned for High Reliability

In addition, the ZRD rotary valve, developed by Coperion specifically for plastic recycling, ensures reliable discharge of flakes through new drive technology and rotor-to-housing gap design.

The K-Tron K3 vibratory feeder is equipped with a unique drive system, suitable for high-precision feeding of recycled materials.

At K 2025, Coperion will demonstrate the synergistic effects of its technology through 3D simulations. The audience will gain an in-depth understanding of the operation of complete systems and the functions of each individual component. All components and technologies from Coperion feature high output, high-quality end products, and exceptional efficiency. For instance, Coperion recently successfully commissioned chemical plastic recycling production lines at two customer plants, each with a processing capacity of up to 6,000 kg/h.
