This developed upcycling process enables the waste-free recycling of heavily printed plastics materials. It works via a multiple step process, supported by reactive additivation in dependence of color and printing ink system of the input materials. Finally a homogenous grey regranulate, fully compatible with REACH, is leaving the upcycling process. This regranulate can be dosed for 100 %, so without any use of virgin polymers, into a new sheet production process or just used to create other circular plastics products.
All additives were developed in several research projects done and are produced as masterbatches at the strategic recycling partner Walter Kunststoffe GmbH itself. These masterbatches follow a new nomenclature starting with "WK UP®", an again registered trademark for innovative compound and masterbatch products (i.e. WK UP®sorb O 2965, WK UP®cycle DUO 9181, ... ).
These products are commercially available via signing a licence of use (-> licence request).
