Making advances with recycling lines


Technology groups are focusing on all process stages to enhance efficiency and quality for recyclers, writes Chris Saunders in this round-up of new machinery developments


The boundaries between plastics compounding and recycling are becoming increasingly blurred. As recyclers are asked to produce materials with tighter specifications, and compounders face grow- ing demand for higher recycled content, equip- ment manufacturers are developing lines that combine feeding, extrusion, filtration, devolatilisa- tion, compounding, and pelletising, into increas- ingly integrated production systems. At the same time, the emphasis is shifting from simply process- ing more volume to processing difficult feedstocks more efficiently while still delivering material quality. New systems increasingly seek to optimise material flow, an approach particularly important for post-consumer recycled (PCR) plastics where contamination, moisture, variable bulk density, and inconsistent polymer composition, can make consistent extrusion difficult. In response to rapidly growing demand for high-capacity polyolefin recycling systems, at K2025 Nordson BKG, part of Nordson Corpora- tion’s Polymer Processing Systems division, and Fimic, announced a strategic collaboration to deliv- er fully integrated solutions capable of processing up to 6 tonnes/hr of PCR plastics. The partners say these solutions address key industry challenges, including material variability, filtration limitations, and costly downtime. By integrating Nordson’s advanced gear pumps, valves, and underwater pelletising systems with Fimic’s high-performance filtration units, the systems ensure consistent pressure, superior filtration, and pellet homogene- ity, even at high throughputs. To meet the diverse demands of high-capacity

polyolefin recycling, the companies engineered a modular system architecture offering exceptional operational flexibility in three configurations, DO (Discontinuous Operation), CO (Continuous Opera- tion), and CFO (Continuous Flexible Operation), each tailored to specific production environments. Key features include: seamless integration from twin-screw adaptor flange to underwater pelletiser; intelligent pump control, modular system design; and minimal operator involvement; which combine to maximise performance and lower Total Cost of Ownership. Meanwhile, the fully automated, intelligent venting process ensures consistent product quality and innovative design strategies, including mobile components and thermal elongation adaptors. In June, Erema held its Edvanced Recycling Days event at its headquarters in Ansfelden, Austria, bringing together industry players from
