The problem with PFAS waste incineration

The U.S. Department of Defense (DOD) released a memo placing a moratorium on the incineration of materials containing PFAS (per- and polyfluoroalkyl substances). According to the memo, the 2022 National Defense Authorization Act requires the ban until the DOD issues guidance implementing the U.S. Environmental Protection Agency’s (EPA’s) interim guidance on the destruction and disposal of PFAS. And, what does the EPA’s current interim guidance say about incinerating PFAS-containing waste? It is best summarized this way: “More research is needed.”
