Abstract:
A method of recycling a casing for a camera, comprising the steps of:providing a camera with a casing that includes transparent portions disposed in front of at least those parts of the camera which need to be exposed to external light and opaque or semi-transparent portions covering other parts of the camera, wherein the transparent portions and the opaque or semi-transparent portions are formed respectively from a transparent rigid resin and an opaque or semi-transparent rigid resin by two-color injection molding, the opaque or semi-transparent resin having the same composition as the transparent resin except for the presence of a means for coloring in the opaque or semi-transparent resin; melting the two-color injected molded casing as collected without distinguishing the transparent rigid resin from the opaque or semi-transparent rigid resin to produce an opaque or semi-transparent resin; and using the opaque or semi-transparent resin material from the melting step as a material for the opaque or semi-transparent portions when forming a new casing of the same type as the recycled casing by the two-color injection molding process.
