Geomelting

Geomelting also known as the Amec process) involves mixing nuclear waste with soil or other glass-formers in large, lined metal tanks. The mix - 20% waste and 80% soil - is heated through two graphite electrodes at temperatures of up to 3,000℃. Gases, mostly carbon dioxide and traces of hydrocarbons, are drawn off and treated separately. The molten substance is then allowed to cool and forms a large glass block that is harder than concrete.

The process, known as vitrification, was devised by the Battelle Memorial Institute in Columbus, Ohio.
