Researchers have discovered a method to eradicate hazardous “eternal chemicals” lurking in your household

For over 70 years, chemical compounds known as “Forever Chemicals” have been used in various products, ranging from non-stick cookware to food packaging. Despite their widespread use, these chemicals have been linked to serious health risks, including certain types of cancer. Recent scientific advancements have led to the development of new methods for breaking down and recycling these seemingly permanent materials, prompting a need for alternative names.

Mark Ruffalo, a fan of the 2019 film Dark Waters, is well aware of the environmental and health hazards posed by per- and polyfluoroalkyl substances (PFAS).

The difficulty in removing PFAS has been a significant challenge until now. Researchers from Oxford University and Colorado State University have collaborated to create a novel technique for not only destroying PFAS, but also recovering valuable components from it.

“The breakthrough in using phosphates to destroy PFAS represents a significant advancement in addressing longstanding environmental concerns,” stated Dr. Longyan, a chemist at Oxford University and the lead author of the study published in Nature.

“Through this effective PFAS destruction method, we aim to shift away from referring to these compounds as ‘Forever Chemicals’.”

So, how was this achieved? The scientists treated PFAS samples with potassium phosphate salts and mechanically ground the mixture using ball bearings to break the strong carbon-fluorine bonds present in PFAS and extract the fluorine content for other applications.

This process is crucial as fluorine is primarily sourced from a mineral called Fluorspar, which is used in various industries including pharmaceuticals and agriculture.

Professor Véronique Gouverneur, the Oxford chemist leading the study, emphasized the significance of recovering fluoride for essential drug production, highlighting the impact of large-scale mining on depleting this resource.

This innovative approach not only addresses the removal of PFAS but also enables the recycling of components to support other industries, making it a potentially beneficial solution for multiple sectors.
