Swedish innovation company RenCom AB announced the start of production of RENOL®, an innovative thermoplastic biomaterial that can be used to replace fossil-based plastics. Following comprehensive studies in Coperion’s extrusion test lab in Stuttgart, Germany, RenCom and Coperion have developed the innovative extrusion process of RENOL®, a lignin-based material. Using Coperion’s ZSK twin screw extruder technology lignin can be transformed into durable, reusable biomaterial.
ZSK 18 MEGAlab with new features for battery
– In October last year, Coperion GmbH supplied a ZSK 18 MEGAlab twin screw extruder and two high accuracy gravimetric Coperion K-Tron feeders to the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) in Ulm/Germany, a leading international institute for research into energy technologies. The Coperion extruder has been specially equipped with new functions for research in the field of battery production, which enable highly flexible use for development work. The extruder also allows for safe handling of the hazardous materials used in the manufacture of battery masses.
Plastic Compounds Out of Packaging Waste
For its innovative, solvent-based plastic recycling process Newcycling®, APK AG in Merseburg, is relying on the high-performance ZSK extruder technology and technical process expertise from Coperion. Using the Newcycling® process, multi-polymer and multi-layer plastic packaging, that previously could not be recycled, can now be separated and processed into homogeneous regrind using ZSK twin screw extruders. In contrast to chemical recycling, the polymer in this process remains unchanged and does not require energy- and cost-intensive re-polymerization. Newcycling®, therefore, is highly efficient from a cost and from an environmental perspective.
Fast Track ZSK Extruders
Italian compounder Sirmax goes forward to invest in technological innovation, continuing strongly in the direction of a sustainable business. The company from Padua (Italy) has expanded its production capacity for sustainable plastics, relying upon Fast Track ZSK extruders from Coperion. These new models stand out for their especially short lead times and subsequent rapid ROI. In Sirmax’s case, Coperion designed two ZSK 70 Mc18 twin screw extruders especially for processing bioplastics. Only five months after placing the order, both Fast Track ZSK extruders have commenced production

After a major fire in their production area in 2017, Aurora Kunststoffe decided once again to rely on ZSK twin screw extruders from Coperion. Those three ZSK 45 Mc18 twin screw extruders have been in successful operation since early 2019, and with their high throughputs and their reliability, they have fulfilled every requirement that Aurora Kunststoffe needs for their innovative business plan.
Visionary Multi-Layer Film Recycling
Coperion GmbH is implementing a closed-loop concept for the production of flexible multi-layer film. Recycling multi-layer film has long posed a challenge since such films can only be reclaimed in very complicated ways and not without residues. Now, however, Coperion has developed a closed-loop approach solution in which up to 100 percent of multi-layer film production waste can be re-processed and fed back into the production process in a closed-loop. For a concrete project Coperion will deliver a recycling system, including bulk material handling, high-accuracy feeding from Coperion K-Tron, and the heart of the system, a ZSK Mc18 twin screw extruder.
