Laboratory Introduction
In 2005, we started research on decomposition of microwave PET bottles using Green Motif I, µ-reactor, etc., and clarified hydrolysis and ester decomposition of titanium oxide catalyst. Recently, it has been clarified that the pressurization condition using Discover, Monowave300, Initiator, etc. proceeds as a non-catalytic reaction comparable to the subcritical condition.
