Volatility and leachability of heavy metals and radionuclides in thermally treated HEPA filter media generated from nuclear facilities

► Thermally treated HEPA filter media was transformed into glassy bulk materials. ► Main radionuclide and heavy metal were Cs-137 and Zn. ► Cs and Zn were transformed into stable form without volatilization and leaching. ► The proposed technique is simple and energy efficient procedure.
