Abstract
A method for disposal of a thermosetting resin containing a material, at least part of which is affected by an alkaline aqueous solution, is disclosed. It comprises at least two steps of including a step of immersing the molded product in an alkaline aqueous solution and a subsequent step of immersing the molded product in water. This method does not require a high temperature as required in a thermal decomposition and does not generate any exhaust gas, and consumes only small energy.
