Abstract

PROBLEM TO BE SOLVED: To provide a method for recycling a solid thermoplastic resin waste. SOLUTION: A thermoplastic resin is added for melting or softening into an oil produced from a solid thermoplastic resin heated in a container and in a pipe to a melting point or above and to an ignition point or below or to a softening point or above, and a melted material or a softened material which has floated is separated and recovered. The melted material, the softened material, or a thermoplastic resin solid which is solidified by cooling is then molded to a pellet form. The melted material, the softened material, or a thermoplastic resin solid which is solidified by cooling is molded to a pellet by adding and mixing a solid such as a waste material with or without heating, or with or without removing the oil, or with or without deodorization.
