Phosphate-enabled mechanochemical PFAS destruction for fluoride reuse
Here researchers disclose a protocol that converts multiple classes of PFAS, including the fluoroplastics polytetrafluoroethylene and polyvinylidene fluoride, into high-value fluorochemicals. To achieve this, PFASs were reacted with potassium phosphate salts under solvent-free mechanochemical conditions, a mineralization process enabling fluorine recovery as KF and K2PO3F for fluorination chemistry.
Biobased Hydrophobic Solutions for Natural Textiles—Moving Beyond PFAS
PFAS are widely used in textiles for their hydrophobic properties but pose environmental risks due to their persistence and toxicity. This review explores natural-based hydrophobic coatings, such as waxes, fatty acids, and natural polymers, assessing their potential as sustainable PFAS alternatives.

New Fluorine-Free Low Surface Energy Surfactants and Surfaces
This article explores the design of PFAS-free low surface energy (LSE) additives as alternatives to hazardous perfluoroalkyl substances. It highlights chemical principles for developing non-fluorinated surfactants and polymeric coatings for applications like microemulsification, firefighting foams, and hydrophobic surfaces. With the phase-out of PFAS, research is advancing toward sustainable, effective substitutes to maintain low surface tension and energy in industrial applications.

PFAS Destruction and Near-Complete Defluorination of Undiluted Aqueous Film-Forming Foams at Ambient Conditions by Piezoelectric Ball Milling
This study reports a novel piezoelectric ball milling approach for treating AFFF with a total organic fluorine concentration of 9080 mg/L and total organic carbon of 234 g/L. Near-complete defluorination (>95% conversion of organofluorine to fluoride) of undiluted AFFF was achieved by comilling with boron nitride.
A state-of-the-art review on green synthesis and modifications of ZnO nanoparticles for organic pollutants decomposition and CO2 conversion
The review covers the exploitation of ZnO-based photocatalysts for the decomposition of diverse organic contaminants, like dyes, pharmaceuticals, phenolic compounds, pesticides, herbicides, PAHs, and PFAS. The mechanisms involved in these degradation processes are elucidated, providing insights into the factors influencing photocatalyst efficiency.
