Abstract: To provide a method for recycling a solar cell module glass, which enables development of other novel applications of a waste glass of a solar cell module while controlling an elution amount of Sb from the waste glass into water. Disclosed is a method for recycling a solar cell module glass, the method comprising: grinding a solar cell module glass into a glass powder; adding at least one foaming agent selected from SiC, CaCO3 and a seashell, and a particular inhibitor to the glass powder to produce a mixture; and heating the mixture to 700 to 1,100° C. to produce a foam glass.

Abstract: Method for treating an incinerated waste material feedstock to obtain a "free-from-ash" ferrous metal product and/or a "metal-free" ash product are disclosed which provide for early separation of the initial feedstock into a predominately ash stream and predominately ferrous metal stream by stepped separation based on size of the material at different stages of the process.
