  • Method of recovering valuable materials from photovoltaic module
    Patent number: 11908969
    Abstract: Provided is a method to recycle valuable materials included in a photovoltaic module having a resin back sheet or the like, for efficiently and easily recovering the valuable materials by removing the resin components from the photovoltaic module. The method of recovering valuable materials from a photovoltaic module, includes: a loading step of loading a photovoltaic module (X) having a resin back sheet and a sealing resin layer on a heat-resistant porous molded body (A) with the back sheet surface facing down; and a heating step of heating a load including the photovoltaic module (X) and the porous molded body (A) in a heating furnace in an oxidizing atmosphere to melt and then combust the resin components.
    Type: Grant
