To achieve a circular economy in plastics, higher proportions of recycled pellets are required in final products

In order to promote sustainable development in the Plastics Industry, implementing recycled pellets in new products is not a sufficient action. The different segments, such as the Consumer sector, also require high quality recycled pellets and a stable recycling process.

To meet this transformer demand, the QualityOn package, from recycling machine manufacturer EREMA, enables continuous quality monitoring during the ongoing recycling process. This means that the current color values ​​of MVR, IV, and the polymer composition of the input material can be measured directly on the machine.

QualityOn: Polysca is installed in the Preconditioning Unit (PCU) of the recycling extruder, and measures in real time the composition of the polymer and the filling of the input material.

According to Clemens Kitzberger, Business Development Manager at EREMA Group, as soon as the measured values ​​leave the defined tolerance range, the machine operators automatically receive a message and therefore it is possible to take measurements in one stage. early or immediately remove reject material from the ongoing process.

“The measurement is based on RAMAN spectroscopy. The interaction of laser light with the material determines its composition. With the exception of very dark and black input material, this method is suitable for all thermoplastics and fillers. The measured values ​​are displayed on the EREMA machine ”.
