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.
Claims6
A method for recycling a solar cell module glass, the method comprising:
- grinding a solar cell module glass into a glass powder;
- mixing the glass powder with at least one foaming agent selected from SiC, CaCO3 and a seashell, and an inhibitor containing a combination of Fe2O3 with CaSO4 or an inhibitor containing Al2 (SO4)3 to produce a mixture;
- and
- heating the mixture to 700 to 1,100° C., thereby melting and foaming to produce a foam glass, and wherein a content of antimony in the glass powder of the solar cell module glass is 5 to 5,000 ppm.
