Although considered essential by our modern society, plastics present environmental burdens from their conception to their End-of-Life, including their use. My postdoctoral project aims to develop viable and sustainable mechanochemical processes to recycle two fossil fuel-based polymers: Polyvinyl chloride (PVC) and Polyamide-6 (PA-6, nylon-6).

PVC recycling rate is drastically low due to its high chloride content (67 wt.%), which contributes to generating corrosive/toxic degradation compounds during thermal processes. The mechanochemical dechlorination route of PVC is promising to lower the formation of low-value hazard compounds, while producing a more valuable feedstock.

Regarding PA-6 recycling, the close-ring depolymerization is a promising method to recover a pure monomer. However, the current processes require high temperatures and/or expensive catalysts to promote this reaction. Could the mechano-catalytic route be more viable?
