Scope

This document describes the method of determining the volatile components of polypropylene (PP) materials using headspace gas chromatography-mass spectrometry, constructing a prediction model using the random forest algorithm, and identifying post-consumption mechanically recycled PP plastic materials from virgin PP plastic materials.
This document is applicable to the identification of granular PP recycled plastic materials made from post-consumption PP as raw materials through processes such as crushing, screening, sorting, washing, and melt extrusion granulation.
This document is not applicable to the identification of recycled PP plastic materials obtained through chemical recycling.
