Abstract: A method for the separation and recovery of foils, in particular aluminum foils, and the other components in waste foil-containing laminates includes subjecting the waste laminates to agitation (7) in a heated polyalkylene glycol polymer solution. The thus heated mixture is cooled to permit density variations to separate (25) the plastic and paper components of the waste laminate from the foil components therein. The separated foil components can be recovered from the polyalkylene glycol polymer solution for recycle or other use. Using a polyalkylene glycol polymer solution permits recovery of the glycol polymer in a heated recovery tank (39) to recycle the polymer to facilitate further foil separation while minimizing adverse effects on the environment.

Abstract: Aluminum can stock is delacquered by treatment with a composition comprising a mixture of a polyalkylene glycol polymer and an aqueous solution of a dicarboxylic acid such as oxalic acid. The cans are cleaned sufficiently for recycling and the solution can be reused to delacquer additional aluminum can stock.
