ABSTRACT:
Multimaterial containers are composed of layers of different materials. Plastic containers are each composed of single resin material. These containers may be granulated and mixed together, heated and moulded, to form new and useful objects. The containers with residue inside and labels outside are granulated to form a material resembling multicolored sawdust. A small amount of sugar is added and the mixture is placed in a mould. Heat is applied to caramelize the sugar and melt the granulated plastic encasing the multilayer particles within the plastic melt. Pressure is applied to remove air from the mould cavity. The mould and contents are cooled and the useful object removed from the mould.
