Plastic recycling is the process of recovering scrap or waste plastic and reprocessing the material into useful products. Since the vast majority of plastic is non biodegradable, recycling is a part of global efforts to reduce plastic in the waste stream, especially the approximately 8 million tons of waste plastic that enters the Earth's ocean every year.

PMMA coatings are useful as a protective bond and release layer for the front surface in wafer thinning. PMMA also affords protection during the subsequent dicing and handling steps. Its thermal and mechanical stability as well as the ease of application, spin coating, and later removal in solvent make PMMA a good candidate for this application.

The mass ratio of PMMA: CeO 2 in the mixed system was 61%: 39%, which was determined by the TGA analysis of the PMMA/CeO 2 hybrid particles. The slurries containing solid ceria particles or (PMMA+CeO 2) mixed particles were prepared with the same procedures, and the polishing tests were performed under the same conditions.
