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.

A method and device for producing piece goods. In order to enable a simple and cost-effective production of piece goods, which have a compact and stable nature and can be admixed to a glass melt in particular during glass production, liquid water glass is mixed with at least one silicate-based solid component, in particular glass powder, to form a mass and is applied in a planar manner to a working surface, whereupon the mass is divided and heated to a temperature below a glass transition temperature, so that piece goods are obtained, in particular one or more dimensionally stable pellets.
