University of Bath Develops New Method for Acrylic Plastics Chemical Recycling
A novel chemical recycling technique from the University of Bath enhances PMMA recovery, achieving over 95% conversion rates. This method, which operates at lower temperatures, could improve the economic viability of acrylic recycling and contribute to sustainability goals.

Researchers at the University of Bath have developed a chemical recycling process for polymethyl methacrylate (PMMA) that operates at temperatures between 120°C and 180°C, achieving conversion rates exceeding 95%. This innovative technique allows for the recovery of over 70% of the material as usable monomer, suitable for repolymerisation into new acrylic products of comparable quality to virgin materials.
The method addresses limitations of conventional mechanical recycling and pyrolysis, which suffer from energy intensity and contamination issues. If scaled effectively, this technology could enhance the circular economy for acrylic plastics, reduce reliance on virgin materials, and lower emissions associated with production.
