    Abstract: A method for recovering face fiber materials and a backing material from a carpet is provided. The carpet includes the face fiber materials, the backing material, and an adhesive. The method includes applying a first mechanical force to the carpet to break a bond between the adhesive and the face fiber materials. The method includes separating at least 25% of the adhesive from the face fiber materials to form a blend of the face fiber material and the backing material. The method includes heating the blend of the face fiber material and the backing material to a temperature sufficient to melt the backing material and convert the backing material into backing droplets, the temperature less than a melting point of the face fiber materials. The method includes cooling the face fiber materials to cause the backing droplets to solidify into granules.
