The findings of the studies reviewed in this report are encouraging concerning the ability of today’s U.S. WTE facilities to effectively treat solid waste that contains PFAS and not emit detectable levels of PFOA in the process. For the formation of PICs, the pilot-scale investigation conducted at the Karlsruhe Institute of Technology is encouraging in its findings that the combustion of PTFE did not create any of the 31 types of PFAS suspected of being potential PICs produced during the combustion process.
In conclusion, based on this research, SWANA is cautiously optimistic regarding the role of WTE facilities in the destruction of PFAS in MSW. The thermal destruction of PFAS in high-temperature combustion systems such as WTE facilities may represent one of the few commercially proven options available to society to destroy these problematic, forever chemicals.
The full report, PFAS Fate and Transport in Waste-to-Energy Facilities, is currently only available to SWANA ARF subscribers. SWANA members receive free access to ARF industry reports one year after publication; the abstract is available online and worth reading.
