A method of treating a process waste stream contaminated with fluorinated hydrocarbons

A method of treating a process waste stream contaminated with fluorinated hydrocarbons, such as per- and / or polyfluoralkyl substances (PFAS), the method comprising: adding a fluoride anion scavenger (e.g. calcium hydroxide) to the process waste stream; adding a base (e.g. sodium hydroxide or lithium hydroxide) to the process waste stream; and heating the process waste stream after addition of the fluoride anion scavenger and the base to defluorinate the fluorinated hydrocarbons liberating fluoride anions which are scavenged by the fluoride scavenger. The heating step may be performed in the presence of a platinum group metal catalyst.
