Near infrared masterbatch for recycling black and coloured plastics

Plastics' recycling in the EU has increased by almost 80 % since 2006*. During the same period, landfill disposal has significantly declined by 43 %. The problem when it comes up to recycling is the fact that some black and coloured plastic items do not get recognized by detecting/sorting machines. That is why these pieces are still disposed as landfill or incinerated to produce energy. So the common use of carbon black still issues the big challenge with it.

The masterbatch can be extruded, blown or moulded by injection, compression, etc. Solutions made with Gabriel-Chemie’s NIR masterbatch have no lower mechanical properties than products made by carbon black-based products.
