Methods and apparatuses recycle glass from used solar modules. Particular embodiments combine optical interrogation such as X-Ray Fluorescence (XRF) with computer-controlled dispensing, in order to obtain refined glass having substantially uniform properties. Such glass properties can include but are not limited to one or more of: elemental content (e.g., Iron), optical transmittance, physical resilience (e.g., resistance to weather damage), and texturee.g., to assist in forming an anti-reflective coating (ARC) and/or encapsulant adhesion. Such optical interrogation is combined with computer-controlled dispensing that regulates the release of glass material through a gate, until one or more specific criterion are met.

The present invention relates to a method for manufacturing glass beads using waste glass and to the glass beads themselves, and more specifically, it pertains to a method for manufacturing glass beadsparticularly glass beads for road markingsby recovering waste glass such as waste automotive glass, waste solar panel glass, and general broken glass. To achieve the above objective, the method for manufacturing glass beads using waste glass according to the present invention includes the step of: a) separating waste glass from a waste solar panel. In this method for manufacturing glass beads using waste glass, step a) includes the process of heating the waste solar panel to a predetermined temperature and cutting the adhesive surface between the waste glass and the backsheet of the waste solar panel using a knife heated to a predetermined temperature.
