ABSTRACT:
A product is made by recycling a beverage container comprising a PET (polyethylene terephthalate) body having a plastic base cup and a metal cap attached thereto. The base cup is made from a plastic material different from the PET. The method includes grinding the entire beverage container including the PET body, the metal cap and the base cup, into particles sufficiently small to flow into a plastics molding machine. The ground particles are fed into a molding machine which heats and applies pressure to them and forces them into a mold of predetermined shape. The molded material is then cooled whereby the molded material hardens and forms a solid object having the predetermined shape of the mold.
