Summary:PROBLEM TO BE SOLVED: To provide a method for reclaiming a scorch-progressed unvulcanized rubber that is capable of recovering flowability and scorch resistance of the scorch-progressed unvulcanized rubber which can not be used in an ordinary use and application due to the progress of the scorch and that is capable of obtaining a vulcanized matter having the characteristics such as hardness and elastic modulus as it is planned, by using the vulcanization condition according to the first plan. SOLUTION: The method for reclaiming a scorch-progressed unvulcanized rubber comprises blending an unvulcanized rubber composition containing 50 wt.% or more of a scorch-progressed natural rubber, with at least one kind of a compound selected from the group consisting of N-(cyclohexylthio) phthalimide, sulfur, N,N'-m-phenylenedimaleimide and a sulfur-releasable type vulcanization accelerator.
