“…The organic components in the latex gloves decompose into gas, oil, and char after liquefaction, but the char and inorganic CaCO 3 are retained in the nal solid product, which is more suitable for underground disposal than the latex gloves. The stabilities of solid products in disposal can be further improved by fabricating proper waste forms (e.g., cement and glass) [11][12][13][14]. Consequently, the burden of storing/disposing latex glove waste generated by nuclear facilities may be reduced by using liquefaction to lower the cost of waste management.…”

“…Hence, the liquefaction process may reduce environmental pollution and relieve public concern regarding gaseous product generation and RI release. The liquefaction of latex gloves should produce a CaCO 3 -based solid product, which can be disposed of easily, compared to the latex gloves, because CaCO 3 can be stabilized in cement and glass matrices as waste forms [11][12][13][14].…”

The accumulation of dry active wastes (DAWs) such as latex gloves in nuclear facilities has become a serious issue because of the high cost and limited storage area for their management. In this study, the liquefaction of latex gloves, which mainly comprise rubber and CaCO 3 , was investigated as a waste reduction technique. When liquefaction occurred at > 270°C, the latex gloves decomposed into gaseous, liquid, and solid products. Cs-, Sr-, and Co-contaminated latex gloves were lique ed at 350°C, and the solid product was subsequently recovered via distillation. Notably, the contaminants comprising CaCO 3 and char only remained in the solid product (~ 33.3 wt.%); thus, the gaseous and liquid products could be regarded as non-radioactive, thereby reducing the volume of radioactive waste (~ 92.7% reduction after compression). Liquefaction is favorable compared to conventional combustion because it generates less harmful gases by converting the organic components to condensed phases.
