Original Abstract Submitted
A system and method for degrading and incinerating a fluorocarbon or fluorinated material, such as per- and/or polyfluoroalkyl substances (PFAS), contained in water, such as ground water or leachate, with reduced emissions of gaseous PFC is provided. The method includes mixing the water, a hydroxide base, and optionally a solvent in a batch reactor to form a suspension. The PFAS and solvent can both be provided by the water, such as ground water or leachate. The reaction mixture is heated to a temperature ranging from about 25° C. to about 400° C. for at least about 0.5 hours to about 240 hours to defluorinate the corresponding PFAS fluorocarbons contained in the leachate water and produce a defluorinated waste product. The method can convert organic fluorine present in the PFAS within the water to inorganic fluoride. Thus, the defluorinated waste product can be incinerated with reduced emissions of harmful gaseous PFCs.
