About
Recycled plastics can retain additives, pollutants and persistent chemicals, limiting their safe reuse and creating risks for human health and the environment. This project treats waste packaging with supercritical water, meaning water held at very high temperature and pressure, where it acts as a powerful solvent. The process removes contaminants to extremely low concentrations while preserving the polymer’s structure so it can be recycled. A purpose-built batch reactor has demonstrated rapid decontamination, and a proposed continuous version could integrate with existing extrusion systems to produce safer, higher-quality recycled plastics at industrial scale.
