1. A method for converting potentially harmful waste material to a less potentially harmful condition, said method comprising:

  • a. providing a glass material in an enclosed horizontally extending conversion chamber, said chamber comprising a rear breakdown area and a forward settling area spaced horizontally from the breakdown area, and maintaining said glass material in a molten condition in a lower portion of said chamber,b. directing said waste material into said conversion chamber at a location proximate said glass material at said breakdown area,c. maintaining said glass material at a sufficiently high temperature to cause the waste material to be broken down into an ash component and a gaseous component, with at least some of the ash component being particulate ash suspended in said gaseous component,d. moving said gaseous component generally horizontally from said breakdown area to a location over said molten glass material in said settling area, with at least part of said suspended particulate ash settling onto the molten glass material in the settling area to form a combined ash-glass material,e. discharging said combined ash-glass material to a cooling zone to form said waste-glass material into a solid waste-glass product.
