PFAS companies plan production surge to meet AI demand, warns ChemSec

The AI industry’s hunger for semiconductors and data center cooling is fueling something less discussed than GPU shortages: a massive expansion of PFAS production, according to a warning from ChemSec, the international nonprofit focused on safer chemical alternatives. ChemSec describes the planned ramp-up as a “tidal wave” of forever chemicals manufacturing, driven primarily by the fluoropolymers and specialty fluids that underpin both chip fabrication and the advanced cooling systems keeping dense GPU clusters from melting down. Chemours at the center Chemours, one of the world’s largest PFAS producers, is expanding capacity at its facilities in Fayetteville, North Carolina, and Parkersburg, West Virginia. The company is actively marketing products like Teflon PFA and Opteon 2P50 as essential components for semiconductor manufacturing and data center cooling fluids. PFAS, or per- and polyfluoroalkyl substances, serve as etchants and photolithography resists in chipmaking, processes where precision at the nanometer scale leaves little room for substitution. They don’t break down in the environment, and contamination from existing Chemours production sites is already a well-document...
