Coperion, together with Herbold Meckesheim, will present their expertise in recycling applications at K 2025.

At the joint booth, the focus will be on Herbold Meckesheim’s technologies for mechanical processing of plastics waste. On display will be the new T 150-300 Mechanical Dryer and the SMS 80-200 Granulator.

In the Open Area “The Power of Plastics Forum” by VDMA, the seamless interplay of all Coperion recycling technologies will be displayed, including a Herbold Meckesheim Hydrocyclone Stage, the ZSK FilCo filtration compounder, the ZS-B MEGAfeed side feeder, a Coperion K-Tron K3-V200 vibratory feeder, an S60 single screw feeder and the MechaTron flat bottom feeder.

High performance using ZSK FilCo with ZS-B MEGAfeed

Coperion’s new ZSK FilCo filtration compounder enables recyclate filtering and subsequent compounding in one step. In comparison to two-step production lines, the ZSK FilCo handles the product very gently and provides higher quality at significantly reduced energy consumption when recycling post-consumer waste and other highly contaminated polymers.

ZSK Filco filtration compounder in combination with the ZS-B MEGAfeed side feeder will be on display at K 2025.

Waste plastics in the form of regrind, fiber pellets, film flakes or agglomerate with no pre-treatment are introduced into a ZSK twin screw extruder where they are melted, homogenized and devolatilized.

The melt is then fed through a filter, removing any contaminants. In the subsequent compounding process additives are introduced into the melt prior to pelletizing the compound.

To fully exploit the ZSK FilCo’s high performance, raw materials must be supplied at a constant rate with no intake limits. While this can be accomplished either by pelletizing the waste plastic or regrind, or by using a compacting process, these are very energy-intensive processes.

The ZS-B MEGAfeed side feeder reliably feeds recycled materials with a bulk density as low as 20 kg/m³ into the ZSK FilCo and other ZSK extruders. This allows for recycling and compounding of lightweight, high-volume fibers and flakes at high throughputs.

Seamless connection of bulk material handling and feeding technology

For feeding technologies with high accuracy and easy handling, Coperion will display a Coperion K-Tron K3-V200 vibratory feeder that excels in providing high-accuracy gravimetric feeding particularly for challenging materials, for example where smaller recyclates or flakes are being fed into the extrusion process.

Coperion K-Tron K3 vibratory feeders are equipped with a unique drive system and are suitable for high-accuracy feeding of recycling materials.

For light and fluffy, hard-to-feed materials such as polypropylene or PET plastic film, Coperion will also showcase the MechaTron FB (flat bottom) feeder, a gravimetric feeder ideal for high-capacity recycling operations. Also on display is the Coperion K-Tron S60 single screw feeder, another feeder the provides very high reliability.

Complete line from single supplier

At K 2025, Coperion will also demonstrate how its various technologies work together through an all-encompassing 3D simulation. Visitors can gain insights into the operation of a complete system as well as the function of each individual component, such as for chemical recycling, recycling PET, deodorizing process during recycling, and more.
