Smoldering of per- and polyfluoroalkyl substances (PFAS) uses the same energy-efficient, flameless form of combustion that Savron has applied both in situ and ex situ to treat a wide range of contaminated soils and organic wastes.

While it’s true that PFAS have a high thermal stability and do not support smoldering combustion on their own, these challenges can be overcome. In our process, a surrogate fuel is added to sustain smoldering combustion and reach the high temperatures at which PFAS are destroyed.

With a surrogate fuel, smoldering has been demonstrated to reduce PFAS concentrations in impacted soil and spent media to near or below detection limits. By adding small quantities of amendments (for example, calcium oxide), most fluorine can be retained in the treated material in an inert mineral form, rather than being emitted into the air.

With Savron’s advances, smoldering is now a viable and cost-effective way to rapidly destroy PFAS onsite, with minimal treatment residuals.
