EPA Proposes New Set of Rules to Regulate PFAS Under RCRA
Policy
15 Feb 2024
The U.S. EPA proposed two regulations that would add nine PFAS to the list of Resource Conservation and Recovery Act "hazardous constituents" and broaden the definition of "hazardous waste" applicable to corrective action at waste facilities, which taken together, would significantly enhance EPA's authority to regulate PFAS.

Smouldering to treat PFAS in sewage sludge
Science
25 Apr 2023 | Waste Manage.
Smoldering combustion completely removed all 4-8 carbon chain length PFAS from sewage sludge under all conditions, though extremely high temperatures and the addition of CaO were needed to mineralize the PFAS completely.

Destroying ‘Forever Chemicals’ is a Technological Race that Could Become a Multibillion-dollar Industry
News
6 Feb 2023 | Inside Climate News
How do you destroy pollution so stubborn, it’s nicknamed ‘forever chemicals’? That’s a question researchers and companies across the country are eager to answer, as regulation tightens on PFAS, or per- and polyfluoroalkyl substances, and the chemicals’ producers face a mountain of lawsuits.

Occurrence and removal of per- and polyfluoroalkyl substances (PFAS) in leachates from incineration plants: A full-scale study
Science
2 Dec 2022 | Chemosphere
Using biological treatment and membrane filtration effectively moved over 95% of PFAS from the leachates from incineration plants, with physical entrapment, not biodegradation, as the main means of PFAS reduction.

Legacy and emerging airborne per- and polyfluoroalkyl substances (PFAS) collected on PM2.5 filters in close proximity to a fluoropolymer manufacturing facility
Science
9 Nov 2022 | Environ Sci Process Impacts
Twelve emerging and ten legacy PFAS compounds were detected in aerosol samples around a fluoropolymer manufacturing facility at concentrations higher than at regional background sites, suggesting the manufacturing facility as the local source for these compounds.

Use and release of per-and polyfluoroalkyl substances (PFASs) in consumer food packaging in US and Canada
Science
11 Oct 2022 | Chemosphere
Most food packaging does not contain intentionally added PFAS, indicating that PFAS are not necessary for food packaging, yet the thousands of tonnes of PFAS still used have the potential to contaminate the environment and waste streams.

Per-and polyfluoroalkyl substances in the atmosphere of waste management infrastructures: Uncovering secondary fluorotelomer alcohols, particle size distribution, and human inhalation exposure
Science
29 Jul 2022 | Environ. Int.
PFAS were prevalent in the air and in particulate matter near landfills and wastewater treatment plants, and modeling demonstrated that fine and ultrafine particles may carry PFAS into the lung alveoli.

The First Quantitative Investigation of Compounds Generated from PFAS, PFAS-containing Aqueous Film-forming Foams and Commercial Fluorosurfactants in Pyrolytic Processes
Science
13 Jun 2022 | J. Hazard. Mater.
Pyrolysis of AFFF and fluorosurfactant samples resulted in the formation of 1,4-dioxane, benzene, and other non-fluorinated compounds, as well as fluorinated volatile compounds, suggesting the uncontrolled heating of PFAS is harmful to the environment and human health.

Critical Review of Thermal Decomposition of Per- and Polyfluoroalkyl Substances: Mechanisms and Implications for Thermal Treatment Processes
Science
2 May 2022 | Environ Sci Technol
This review discusses thermal treatment as a way to destroy PFAS, and highlights that a major weakness of existing studies is that they do not mimic the full-scale thermal treatment systems that are actually used for PFAS incineration.

Levels and Temporal Trends of Trifluoroacetate (TFA) in Archived Plants: Evidence for Increasing Emissions of Gaseous TFA Precursors over the Last Decades
Science
26 Apr 2022 | ES&T
TFA concentrations in plants were found to increase over several decades, likely due to increasing anthropogenic emissions of TFA precursors. The very high persistence and mobility of TFA in the environment mean that TFA and its precursors should be considered for regulation.
