Abstract
The ability of natural abrasives which were recovered from CRT glass polishing process was evaluated. Comparing the center line average roughness values of a glass polished with new pumice (Ra = $0.039{\mu}m$) and with new garnet (Ra = $0.031{\mu}m$), the glass surface polished with the recycled pumice and the garnet had less pits on the surface with smaller Ra values (Ra = $0.025{\mu}m$ for recycled pumice and Ra = 0.029 for recycled garnet). Recycled rouge contains amorphous glass fragments so that it should be used as a cement replacement rather than recycle into an abrasive. Nnatural abrasives, pumice and garnet powder, which are used in CRT glass polishing process can be recycled into abrasives so that it can help to minimize costs and environmental impact from the production of abrasives and the disposal of waste sludge.
