Abstract An efficient one‐step extraction method was developed for the recovery of additives and non‐intentionally added substances (NIAS) from polystyrene, performed at room temperature 2.33 h, without grinding to avoid fostering formation NIAS unrelated polymer processing. Solvent use (39.2 mL/g) greatly reduced compared with conditions previously reported. The study is analytically challenging but high importance since their presence a potential threat human health environment while reducing plastic recyclability. For an understanding influence processing parameters, systematic approach taken, using virgin polystyrene mixed known quantities standard as model materials (Irganox_1076, Tinuvin_326, Irgafos_168). degradation one additive identified by NMR GC–MS. Precise multiple‐point quantification internal GC–MS, measuring 5.1 wt% Irgafos_168 degradation, LOD ranging 0.55–0.95 ppm. Evaluation analytical challenges, such matrix effects, discussed quantified. This will help quality control recycled PS materials, including food contact ones, improve knowledge impact on formation.

ABSTRACT Synthetic plasticizers are essential additives widely used in polymer‐based products such as food packaging, toys and medical devices. Despite their functional properties, they present significant environmental human health risks due to toxicity migration behaviour. Growing awareness of these adverse effects has driven interest the development bio‐based derived from natural resources. In recent years, have emerged promising alternatives, offering advantages low toxicity, biodegradability reduced migration. Their application is particularly relevant packaging industry, where transition towards sustainable materials gained great interest, with growing use biopolymers starch, poly(lactic acid) (PLA), chitosan gelatin. Most exhibit limitations barrier, mechanical processing requiring addition improve performance. Natural provide a synergistic solution by enhancing properties while maintaining sustainability resulting materials. Furthermore, compatibility makes them highly suitable for industrial applications. This review explores advancements plasticizers, integration into biopolymer systems challenges associated industrial‐scale adoption
