Abstract
Hazardous waste is formed into non-hazardous non-leaching aggregate by introducing particulate noncombustible material into at least one oxidizer beneath the surface of an accumulation of molten noncombustible material. It is preferred that the walls of a portion of the apparatus be comprised of a layer of refractory material containing metal pins over a metal-walled, water-cooled vessel.
