Nexam Chemical is about to recycle black plastic


 The demand for sorting different fractions of polymers for recycling is increasing rapidly. Today, FT-IR and NIR* technology is used to detect and sort polymers, but so far it has been impossible to sort carbon black polymers.

Recently, however, other black pigments that can replace carbon black color and at the same time be detected with NIR spectroscopy have been developed. With the help of these new solutions in NIR technology, Nexam Chemical has conducted successful tests for the detection and sorting of black polymer articles.

The tests were executed at TOMRA’stest facility in Germany. Read more about recycling of black pigments in the next newsletter.
