METHOD FOR MEASURING TRACE CONSTITUENT CONTAINED IN THERMOPLASTIC WASTE PLASTIC, METHOD FOR RECYCLING THERMOPLASTIC WASTE PLASTIC

摘要

PPROBLEM TO BE SOLVED: To provide a method for measuring a content of a harmful material contained in the thermoplastic waste plastic simply crushed, and recycling the thermoplastic waste plastic into a plastic product having a standard for the content of the harmful material contained in the crushed thermoplastic waste plastic. PSOLUTION: The method for measuring a trace constituent contained in the crushed thermoplastic waste plastic has: the process (b) for uniformizing the crushed thermoplastic waste plastic; the process (c) for partially extracting the uniformized and crushed thermoplastic waste plastic, and converting it into a solid particulate material by heating, melting, mixing and kneading it; and the process (e1) for partially extracting the solid particulate material, and analyzing the trace constituent contained in the solid particulate material.
