GeoMelt® technologies are a group of vitrification processes that are configured in a variety of ways to meet a wide range of radioactive and hazardous waste treatment and remediation needs. GeoMelt® vitrification destroys organic wastes and immobilizes radionucludes and heavy metals in an ultra-stable glass similar to obsidian and typically 10 times stronger than concrete.
• Joule heated melting technology for hazardous radioactive waste treatment and immobilization• Commercially proven on radioactive heavy metals and organic wastes in the US, Japan, UK, and Australia• Invented by Battelle for US DOE; we own exclusive world-wide rights• GeoMelt® In-Container Vitrification (ICV)™ treats radioactive wastes in
single-use containers; the melter is the disposal container• GeoMelt® ICV™ has treated a wide variety of mixed radioactive waste
chemistries at scales ranging from ½-tonne to 50 tonnes melts
The GeoMelt® vitrification process offers significant advantages for radioactive and hazardous waste treatment and site remediation:
• Commercially proven at large scale• Produces a superior chemically and mechanically durable wasteform• Scalability, flexibility, simplicity, and high waste loadings improves
project economics and reduces lifecycle costs• Simultaneous processing of mixed organic, inorganic, and radioactive wastes• High radionuclide retention• Permitted by the US EPA for treatment of PCBs (99.9999% proven destruction and removal efficiency)• Operating plants in the UK and Japan
