Background
Reducing or eliminating chemicals and polymers of concern play a part in mitigating plastic pollution through increasing circularity potential as well as reducing toxic impacts during usage, and when leaked.

Chemicals of concern within plastics include a plethora of substances that are intentionally added (additives, such as chemicals, colourants, fillers or reinforcement) or are Non-Intentionally Added Substances (NIAS), which form as byproducts of processing, degradation and contamination reactions. Here, we specifically focus on the additives as chemicals
