Towards Safer Recycling: A Novel Framework for Identifying Chemicals of Concern in Plastic Waste

We present a framework to identify chemicals of concern (CoCs) in plastic waste by combining polymer–sector usage with literature‑based concentration ranges and hazard scoring, then ranking substances via a Concern Rating Indicator (CRI) to highlight those most likely to reappear in recycled plastics and merit regulatory prioritization.

How to reproduce
See README.md for exact steps to set up the environment and run the workflow end‑to‑end (data prep → computation of potential presence → hazard scoring → CRI ranking → export of tables/figures). The pipeline is deterministic and tied to this archive’s versions of code and data.
