Method for separation of beverage bottle components

摘要: A method for separation of beverage bottle components including high density polyethylene (HDPE) basecup; poly ethylene terephthalate (PET) body; aluminum cap; paper/plastic labels and adhesives, disjoining, isolating separating the various components. The essentially involves steps of: bisecting bottles into two halves to disengage cap from heating bisected so as cause thermal softening adhesives; mechanically thermally loosened assemblage; subjecting isolated a flotation tank; collecting light (floating fraction) heavy (sunk fractions separately; air classifying HDPE fraction remove labels; (aluminum PET) due their size differential.
