ing moisture from sorting systems on a large scale to produce agglomerates with high bulk density that can be used as a feedstock for chemical recycling and other applications. “It’s our job to build machines that support chemical recyclers in the recovery of low-grade waste fractions,” said Klaus Lederer, business development manager for chemical recycling at Erema. Agglomera processes contaminated waste
streams with a low bulk density (from 30 kg/m³) and moisture contents of up to 12% – by combin- ing the Erema preconditioning unit (PCU), its Counter Current technology and a special extruder screw. Even when the composition of the feed material varies – such as in terms of polymer, geom- etry and moisture – the combination ensures stable process control. Material is homogenised, de- gassed, preheated and fed into a short extruder without upstream drying. “Conventional agglomeration systems quickly
reach their limits if the feed material has a low bulk density or fluctuating parameters, but this is not a problem for Agglorema,” said Lederer. From the extruder, the partially melted material strand is fed through a melt pipe into the water-
cooled melt mill. Here, it is formed into agglomer- ates with bulk densities of 280 to 380 kg/m³ and a defined particle size. Agglorema can be used to prepare feedstock
materials for chemical recycling and mechanical recycling. Agglomerates derived from mixed polyolefin fractions can be used to make simple components, he said. Erema will also show its PredictOn system, which monitors and record changes in the plasticising unit. It allows early detection of potential issues to prevent unscheduled downtime. Integrated into the machine display (HMI) and the BluPort digital customer platform, it raises the overall efficiency and productivity of recycling systems, says Erema. Ultrasonic sensors detect wear to the extruder
screw and barrel in real time without direct contact with the melt. Dimensional changes are displayed on the machine HMI using a traffic light colour system, and long-term data can be viewed online on the BluPort platform. PredictOn will be demonstrated on an Intarema TVEplus DuaFil Compact, processing different input materials. �
