repeated sorting cycles until optimal separation and sorting is complete. The vision inspection and sorting technology enables the recovery of high value polymers by separating by contamination, colour, size, and shape. Finally, the company introduced its new Raw Material Inspection Lab Model leveraging the same vision inspection technology but as a more compact desk top system.
Even flow At K2025, granulating machine manufacturer Hellweg Maschinenbau presented Smart Flow, an online flow measurement system, and announced it will be integrated into its products to complement the existing Smart Control system. Combined, the tools will provide a solid basis for the integration of self-learning artificial intelligence (AI) modules, considered the next step in the evolution of quality control, and calculate the optimum ratio between material properties, feed, and required power during granulator operation. The system will then regulate the machine parameters to maximise energy efficiency without human intervention. At Smart Flow’s core is a sensor positioned in the riser pipe that measures the flow rate (bulk flow) without contact. The data is transmitted to the Smart Control system, where it is processed, extrapolated, and displayed. Statistical values such as the grinding performance can also be called up and made available automatically for customer MES and planning tools. The reliability, precision and repeatability of the data is based on the sensor’s operating mode, which uses microwave technology to measure bulk flow and requires no maintenance. “Thanks to Smart Flow, we and our customers have access to a valuable additional option for planning maintenance work and avoiding unforeseen downtime, beyond the display of data,” said Managing Director Mark Hellweg.
Future beckons AI is creating a buzz in the industry, but we are yet to see many clear-cut, practical applications. Quality control and equipment monitoring, however, are two areas where its influence is being felt. Pellenc ST, the French producer of optical sorting solutions, is launching AISEE, an AI-based quality control analyser. Unlike traditional sorters, AISEE focuses on monitoring, analysing, and improving the quality of recyclable fractions, while reducing material losses. According to Vincent Castaignède, Director of ValcopIA, Paprec Group, “the AISEE is becoming a real tool for speeding up commissioning phases and aiding decision-making.” The system improves the quality of sorted

material through fine-tuning of optical settings and reduces recyclable material losses, identifying errors in feedback loops and providing detailed insights into waste composition. Its native OPC UA connectivity with Pellenc ST Mistral+ Connect optical sorters allows faster adjustments and simplified fine-tuning while on-site support from technicians ensures that data-driven insights translate into actionable improvements. Data collected by AISEE is securely presented via
the Smart&Share application, which is ISO 27001 certified and allows operators to access dashboards and reports remotely. By combining AI-powered quality control with advanced sorting technology and dedicated expert support, Pellenc ST said it is positioning AISEE as a key tool for maximising recovery and furthering a circular economy. Sesotec says it is intensifying its cooperation with long-standing distribution partner Popgro in Hungary and Slovakia with the aim of providing customers with more targeted support in the form of solutions for product inspection and sorting. As a regional contact, Popgro will support customers in the selection and implementation of Sesotec solutions for foreign object detection, material analysis, and sorting, and is expanding its product portfolio with various Sesotec products including a Flake Scan analysis system, a Re-Sort unit for recovering separated materials, and a Pre-Sort system for sorting and processing regrind. “In Popgro, we have gained a partner who shares our values and understands our mission,” said Joachim Schulz, CEO of Sesotec. “Together, we are developing solutions that not only increase quality and productivity, but above all create the conditions for realizing a true circular economy in the plastics industry.”
