PURPOSE: A method for manufacturing a foamed body and the foamed body are provided to obtain foamed glass through a foam-plasticizing process by pulverizing the glass of wasted liquid crystal display and mixing the pulverized glass with a foaming agent. CONSTITUTION: A hydration reaction is implemented with respect to the glass of wasted liquid crystal display in order to extract indium and tin components from the wasted liquid crystal display in the hydration solution. The hydration solution and the wasted liquid crystal display are separated. A washing process is implemented. A foaming agent composition is added to the hydrated wasted liquid crystal display in order to obtain a raw power mixture. A sintering aid functioning as a binder and water are added to the mixture. The mixture is shaped into a spherical shaped product and a massive shaped product.
