Depolymerization of PMMA-based Dental Resin Scraps in Dif-ferent Production Scales
AI summary Read the abstract
This study examines how waste dental PMMA (a common plastic) can be broken down via pyrolysis to recover methyl methacrylate monomer, with viable yields across laboratory and pilot scales at temperatures below 450°C. The work contributes to chemical recycling strategies for plastic waste, important for reducing the volume of plastics that ultimately fragment into microplastics in the environment.
