ABSTRACT:
Plastics having coatings are reused by first removing the coatings as by shaving or treatment with solvents or jets of hot liquid or vapor that melt the coatings and blow them away. Thin plastic pieces like compact discs are passed through surface milling apparatus which shaves off the coatings. After the shaving, the discs are brushed while rotating around their centers.
