Claims7
A process for separating and recovering the laminae of a rigid, narrow-necked plastic bottle having laminated walls, the laminated walls including a fluid-barrier lamina of a flexible non-frangible material which is highly impermeable to fluids, and a load-bearing lamina of a frangible plastic material which will delaminate from said fluid-barrier lamina when said bottle is crushed, said process comprising:
- (a) crushing said plastic bottle to separate said flexible, non-frangible, fluid-barrier lamina from said frangible load-bearing lamina to break said load-bearing lamina into chips, and
- (b) separating said chips from said non-frangible fluid-barrier lamina.
