Abstract: In a process for recycling waste fabric comprising elastomeric material a polar solvent is flowed through the waste fabric in an extraction chamber to dissolve and remove the elastomeric material; the solvent is evaporated in an evaporation chamber and condensed to be sent to a solvent collection tank or back to the extraction chamber; the dissolved elastomeric material is eventually recovered from the concentrated polar solvent.
