Miermans, C.J.H. (author), Dijkmans, E. (author), Krystek, P.W. (author)The ability to track & trace materials is a key feature in the entire chain, and it ensures circularity principles. Examples from plastic recycling show the enormous added value that analytical technology can have for the circular economy. During polymer production and recycling processes, pigments can be added for different purposes; e.g. as...article 2020
