The Vitrification process utilises a glass furnace having a refractory lined bath containing molten glass and heated by an oil / oxygen flame at temperatures in excess of 1600°C.
Blended waste materials are fed into the furnace and are effectively destroyed. Inorganic compounds dissolve into the molten glass bath fusing all the components together, toxic and non-toxic. Carbon based compounds undergo complete combustion due to the temperature of the furnace and asbestos minerals melt and dissolve into the molten glass, never to reform. A furnace glass residence time is greater than 6 hours and a gaseous phase residence time greater than two seconds. This offers maximum opportunity for the fusion of hazardous components into the glass and complete combustion of carbon compounds.

Analysis of all waste materials, processes, flue gases and products is essential for a process integrity, material audit, consistent product and customer satisfaction.
