Erema increases efficiency in post-consumer recycling

Large plastics recycling plants need more than simply upscaling the individual components. The larger the size of the extruder screw, the greater the technological challenges. The start-up last summer of the largest Intarema system to date, with a throughput of over four tonnes per hour, confirms that EREMA offers reliable solutions for high throughputs. The next smaller size 2021 has now been further developed. At the K show, Erema will launch the Intarema 2021 TVEplus with a diameter of 2 metres for the preconditioning unit (PCU) and 212 millimetres for the extruder screw, which for the first time features a single end-to-end extrusion unit. With a throughput of up to 3.5 tonnes per hour and a footprint of just 15.1 x 3 metres, this recycling system is over two metres shorter than the previous cascade design, in which two extruders were connected by a melt pipe. The new design also reduces the melt temperature, lowers energy consumption and minimises maintenance requirements.
