Abstract Handling the waste associated with halogenated polymers is a daunting task due to well‐documented emission of halogen‐bearing toxicants during disposal or recycling operation. According Stockholm Convention treaty, most these products are classified as persistent organic pollutants their potential health hazards. This review aims provide holistic overview recent updates for treating polymeric through physical, chemical and biological approaches. In line inquiry, critical analysis obstacles prospects each degradation technique on polymer has been performed, assessing based efficiency, treatment upscaling, pollution control, feasibility. Though many treatments show promising results, they also entail drawbacks. Thermal exploiting various metal oxides, especially calcium additives, considered executable valorization coupled mineralization/metal extraction its intuitive operational feasibility scalability. Strategies combating soaring wastes summarized herein tap into promoting circular economy approach sustainable

The products of incomplete destruction (PIDs) per- and polyfluoroalkyl substances (PFAS) represent a substantial ambiguity when employing thermal treatments to remediate PFAS-contaminated materials. In this study, we present new information on PIDs produced in both inert oxidative environments from five long-chain PFAS, including three now regulated under the U.S. Safe Drinking Water Act, one cationic precursor compound, C10 PFAS. data did not support generation tetrafluoromethane any studied carbonyl fluoride was found only potassium perfluorooctanesulfonate (K-PFOS) heated air narrow temperature range. Oxidative conditions (air) were observed facilitate PFAS degradation accelerate mineralization K-PFOS. Spectroscopic suggest that is initiated by cleavage bonds form perfluoroalkyl radicals, leading organofluorine (e.g., perfluoroalkenes). air, radicals react with oxygen oxygen-containing PIDs. enhanced adding solid additives, which categorized as highly effective granular activated carbon (GAC) certain noble metals), moderately effective, noneffective. Remarkably, simply GAC, achieved >90% perfluorooctanoic acid at 300 °C ∼1.9 atm within just 60 min without using water or solvents.
