AI data center expansion drives rising PFAS production and recycling innovation

The rapid expansion of artificial intelligence infrastructure is driving increased production of per- and polyfluoroalkyl substances (PFAS), also known as ‘forever chemicals’. According to a report by ChemSec, major chemical manufacturers including Daikin, Arkema, and Chemours are expanding capacity to meet the demand for PFAS used in semiconductor manufacturing, lithium-ion batteries, and data center cooling systems.

As data centers generate immense heat, many operators are shifting from water-based cooling to fluorinated chemical solutions due to their heat resistance. This shift has raised environmental concerns; 17 environmental organizations recently petitioned the US EPA to block the approval of a new PFAS chemical, Opteon 2P50, citing risks of gas release and leakage. While Chemours maintains its systems are closed-loop with low emissions, critics warn of the long-term pollution and high social costs associated with these substances.

In a related development, researchers led by the Nagoya Institute of Technology have developed a method to recycle PFAS. The team utilized spinning metal balls to break down PFAS waste at room temperature, successfully recovering approximately 95% of the fluorine within 10 minutes. This technology aims to transform these persistent pollutants into valuable resources for use in medicine, electronics, and refrigeration.
