The expectations that Nosoplas placed on the retrofit with a Gneuss Rotary Filter have been completely fulfilled. Immediately after commissioning the units, a drastic reduction in in material loss due to back flushing was observed and, at the same time, the quality of the rPET granulate produced was noticeably improved.

The processing of PET Bottle Flakes presents particular challenges for Melt Filtration Systems. On the one hand, the post-consumer material source typically has a relatively high contamination level, on the other hand, the quality requirements (fine filtration) are very high – especially when the material is to be put back into transparent bottles for beverages.
