The Fate of Fluorine Post Per-and Polyfluoroalkyl Substances Destruction during the Thermal Treatment of Biosolids: A Thermodynamic Study
Science
15 Jul 2024 | Energies
PFAS found in biosolids can be partially destroyed and converted to smaller compounds during thermal treatment, with factors like feedstock composition and the addition of minerals significantly affecting the emission and capture of fluorine compounds, offering insights for optimizing thermal treatment processes.

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.
