  • Method for the purification and recovery of non-gelatin colloidal waste encapsulation materials
    Patent number: 6726841
    Abstract: Method for treating non-gelatin colloidal encapsulation waste materials in which the waste is combined, optionally, with a solvent capable of dissolving the non-gelatin colloidal encapsulation material, and any softening agent contained therein, and then treating the solvent layer to remove contaminants such as residual oils and/or particulates which may be present, to provide a purified and usable encapsulating material containing stream.

  • Method and apparatus for the recovery of non-solvent type fills from gelatin capsules
    Patent number: 6361802
    Abstract: Method and apparatus for recovering non-solvent fills from a gelatin-containing material by adding the gelatin-containing material to a suitable solvent to form a mixture including a solvent phase and a phase containing said non-solvent fill and then separating the solvent phase from the phase containing said non-solvent fill, followed by recovering the non-solvent fill.
