Recycling sorter UniSort Black

Effective diversity: reduction of sorting residues, increased plastic ratio, higher plastic extraction, removal of black PVC and cleaning of green waste We have developed the UniSort Black as a further stage of expansion of the proven UniSort PR line. And all materials detectable using NIR are reliably recognised because the UniSort Black also operates with our in-house HSI camera technology. The UniSort Black can additionally detect dark or even black objects due to its special arrangement and adapted classification system. The latter otherwise remain invisible to standard NIR sorters. The main field of application for this technology therefore lies in the accumulation of dark objects. As an additional post-removal stage in a post-consumer packages system, for example, the UniSort Black can positively sort all previously undetected dark objects and convert them into a product. This also applies to the remaining losses from upstream sorting technology. From an annual perspective, the input into a post-consumer packages system consists on average of around 3% black packaging, which is not separated out by conventional NIR separators. Examples of this packaging are primarily cosmetic products for men, dark fabric detergents or PP plant pots. Consequently this packaging, generally made of PP or PE, passes through the entire processing and inevitably ends up in the plant's sorting residues. The PP and PE plastics that are so important for the sorting system's overall extraction and related plastic ratio cannot be detected and require expensive disposal.
