ColorIn & ColorOut
- Packaging waste is the largest "raw material reservoir" for polyolefin recycling. The three main obstacles to the widespread use of the recyclates produced from it are odor, NIAS and color.
- The largest proportion of polyolefin waste is colored. So, what good is the most pleasant-smelling recycled material if it is still grey, brown or black at the end?
- Decolorization of recycled materials therefore has both a high economic as well as ecological potential. This potential is leveraged by combining a suitable coloring process with an innovative decoloring process.
- Decoloring by solid-liquid extraction simultaneously eliminates unpleasant odors and removes NIAS from the plastic, so that all 3 major challenges for the use of recyclates are addressed at the same time.
