The invention relates to a method for producing foam glass by recycling a waste glass mixture containing screen glass from television sets, computers, or other monitors and glass from fluorescent tubes and/or energy-efficient light bulbs and/or photovoltaic systems, comprising the steps performed in the following sequence: separately grinding individual fractions of the waste glass, which originate from different sources, to form glass powder; mixing a glass sintering mass comprising components of the various glass powder fractions and an inorganic carbon carrier substance as an activator in a dry process without adding water or other liquids; and thermally treating the glass sintering mass, wherein the glass sintering mass is first subjected to a sintering process and later to a foaming process, which occurs at temperatures in a temperature range of 855 °C to 890 °C, and the arising foam glass is subsequently cooled down. According to the invention, the glass sintering mass, which is composed of thermally sintered glass powder and activator, is composed of at least 10 wt% of screen glass when 85 to 90 wt% originate from screen glass and glass from fluorescent tubes and/or energy-efficient light bulbs and/or photovoltaic systems. |
