Systems and methods are provided for treating, degrading, and incinerating fluorocarbons or fluorinated materials, such as Freon ® with reduced gaseous perfluorinated compound (PFC) emissions. The methods include mixing a fluorinated material with a hydroxide base and optionally a solvent system (e.g., diglyme, polyether, polyether alcohol, polyethylene glycol selected from ethylene glycol and PEG 50 to PEG 3350, N-methyl pyrrolidine, dihydrolevogluton, and / or water ("solvent")) in a batch reactor to form a reaction mixture (also referred to as a suspension). The reaction mixture is heated to a temperature in the range of about 25 °C to about 400 °C for about 0.5 hours to about 240 hours to defluorinate the fluorinated material and produce a defluorinated waste product. More specifically, the methods convert organic fluorine present in the fluorinated material, such as Freon ® to inorganic fluorides. As a result, the defluorinated waste product can be incinerated with reduced harmful gaseous PFC emissions.
