To provide a method for recycling an automotive ceiling material whereby an automotive ceiling material comprising a laminate of different materials can be recycled easily, quickly, and separately.
In recycling an automotive ceiling material 1 comprising a ceiling base material 2 made of a foam of a polymer blend of polyphenylene ether and polystyrene, a surface layer 3 laminated to the base material 2, and an abnormal noise prevention layer 4, the ceiling material 1 is immersed in limonene 8; then, external force (centrifugal force) is applied to the ceiling material 1 immersed in limonene 8 to separate the surface layer 3 and the abnormal noise prevention layer 4 from the base material 2; thus, the surface layer 3 and the abnormal noise prevention layer 4 are separated from the base material 2 without fail and recovered, e.g., even when the ceiling material 1 has strongly bonded parts or intertwined parts.
