The most promising ways to destroy ‘forever chemicals’

🗞️ Driving the news: Scientists are advancing multiple technologies to destroy PFAS, or “forever chemicals,” notorious for their persistence in the environment and links to serious health risks
• New destruction methods — including supercritical water oxidation, ultraviolet light, plasma, and sound wave treatments — are now being tested or deployed, with several already licensed for real-world use
• These developments arrive amid regulatory uncertainty, as the EPA reconsiders its stance on recent PFAS drinking water rules

🔭 The context: PFAS are a class of over 12,000 chemicals used in non-stick cookware, firefighting foams, and industrial products
• Their strong carbon-fluorine bonds resist degradation, making them widespread in soil, water, and food packaging
• Traditional methods of removal often concentrate but do not eliminate the compounds, raising concerns over toxic by-products
• Until recently, the lack of scalable and complete destruction options has stymied efforts to tackle legacy PFAS contamination

🌍 Why it matters for the planet: PFAS pose long-term environmental and health threats, from water pollution to bioaccumulation in humans and wildlife
• New destruction technologies could help remediate contaminated sites without creating additional hazards
• However, experts warn that effective PFAS management must also prioritize production bans and prevention strategies, not just end-of-life solutions
• These innovations mark progress toward a more circular, less toxic economy.

⏭️ What's next: Companies like Revive Environmental and Battelle are scaling up technologies such as supercritical water oxidation at treatment sites in Michigan and Ohio
• Others, including the Colorado School of Mines and Michigan State University, have licensed methods using hydrothermal and UV-based systems
• Researchers continue exploring lower-energy alternatives, but scaling up while managing energy use and ensuring safety will be critical
• Broader adoption may depend on regulatory clarity and stronger global action to restrict PFAS use

💬 One quote: “You don’t carry one screwdriver in your tool belt… and I think that’s going to be the case with these PFAS destruction technologies,” — Christopher Higgins, professor at Colorado School of Mines.

📈 One stat: PFAS have been detected in the drinking water of over 200 million Americans, according to recent environmental studies
