system connects Erema’s Preconditioning Unit (PCU) featuring its patented Counter Current technology directly to a twin-screw extruder for the first time. The launch comes after two years of researching, testing and developing the twin-screw extruder concept, in which Erema worked closely with customers. The company said the resulting system is “particularly adept” at recycling multilayer film production waste but also has good potential for improving recycling of thin-walled post-consumer regrind material.

technically optimised the components of our new RecoStar Dynamic Art recycling systems in such a way that production output and system efficiency have increased significantly.” Special features of the new system include its spin-feed technology. Starlinger said: “Technically sophisticated design elements such as the newly conceived ribs in the Smartfeeder, where the input material is prepared for extrusion, and the special geometry of the cone bushing and the feed zone of the extruder ensure that the material is held longer and enters the extruder with more pressure and spin. This so-called ‘spin feed’ leads to a signifi- cant increase in system performance.”


Automated speed A Dynamic Automation Package helps towards production efficiency by detecting fluctuations in the input material due to differences in bulk density, size, or moisture content, and regulates the extruder speed accordingly. It also responds to interruptions in the material feed by automatically putting the system into standby mode and restart- ing it when production resumes. Along with the RecoStar Dynamic Art on its stand,


Starlinger showed a new underwater pelletising unit. Integrated into the highly automated production process, this works particularly efficiently at high throughput rates and allows the processing of a wide variety of input materials, said the company. A number of exhibits on the Erema stand at K2025 showed how the company is innovating in the interests of film recyclers, in both the post-con- sumer and post-industrial areas. The group launched a twin-screw extruder system designed for low bulk density film recycling. The TwinPro

Erema, claimed the TwinPro system “sets new standards for specific recycling tasks. During development, we focused especially on combining our strengths in material processing with the advantages of a twin-screw extruder.”


Multilayer film In the recycling of multilayer film consisting of PE-PA or PE-EVOH, the TwinPro displays highly efficient homogenisation, according to the com- pany. The first stage of homogenisation takes place in the PCU, which shreds, heats, dries, compacts and buffers the input material. Erema said: “Opti- mised material preparation right at the start of the recycling process lays the foundation for consist- ently high-quality end products.” The extruder is continuously filled with heated


and pre-compacted material from the PCU, which can treat a wide range of materials with bulk densities from 30 to 800 g/litre without the need for separate agglomeration, weighing or a stuffing unit. The intensive homogenisation that then takes place in the twin-screw extruder is essential for multilayer film recycling so that the different polymer types are completely mixed. This produc- es recycled pellets with the improved mechanical properties needed for reuse in multilayer films. Although it was originally developed for


complex film waste, the TwinPro now opens up new capabilities for using twin-screw extruders in the recycling of thin-walled packaging, according to Erema. One particular application is low-density PP flakes that have been sorted and hot-washed from very thin-walled packaging such as yoghurt tubs. The TwinPro set-up enables smooth processing of the low-weight, high-volume material which often causes problems in the material feed on conven- tional twin-screw systems. Other new products shown at K2025 that are


relevant to film recycling relate to Erema’s Intarema TVEplus systems based on a single-screw extruder. The group says it new Volex technology delivers
