Abstract: The internal phase and paper fibres of waste capsule-coated paper is reclaimed by disposing in a container a batch of the paper the density of which is such as to permit the flow of a solution between strips forming the batch, removing the internal phase by pumping into the container a solvent capable of penetrating the walls of the capsules and which has a boiling point lower than that of the internal phase thereby to form an internal phase/solvent solution, then displacing the solution, distilling the solution to recover the solvent and the internal phase, and then removing the treated batch from the container.
