Waste photovoltaic module processing method

Abstract

This waste photovoltaic module processing method is a method of continuously treating a waste photovoltaic module. The method includes a heating step of heating a photovoltaic module having a resin back sheet, etc. in a thermal decomposition furnace to melt and oxidatively decompose resin components included in the photovoltaic module, in which the heating step is performed by moving the photovoltaic module in the thermal decomposition furnace from an inlet of the thermal decomposition furnace toward an outlet in a state where the photovoltaic module is placed on a porous ceramic support (A), and the ceramic support (A) is placed on a porous material (B) carrying a transition metal oxide, and an inside of the thermal decomposition furnace includes a temperature rising section in a stage where a temperature of the photovoltaic module rises, and a combustion section in a stage where the resin components are oxidatively decomposed, and an oxygen concentration in the combustion section is controlled to a range from 6 vol % to less than 15 vol %.
