\n T<\/span>he rise of artificial intelligence<\/strong>\n is driving up demand for semiconductors<\/strong> and\n computing infrastructure<\/strong>. Yet manufacturing\n and cooling them still rely on\n fluorinated substances<\/strong>, some of which belong\n to the vast family of PFAS<\/strong>.\n An investigation by\n ChemSec<\/strong>,\n reported by The Guardian<\/strong>, indicates that several\n major producers plan to expand their capacity,\n citing in particular the needs of\n chips and data centers<\/strong>.\n This signal reignites a complex debate:\n how can chemical persistence and emissions\n be reduced without ignoring the technical functions\n for which alternatives remain difficult to qualify?<\/strong>\n <\/p>\n<\/div>\n\n

\nWhat Just Happened\n <\/h2>\n\n<\/div>\n\n

On September 14, 2026, The Guardian reported the findings of a ChemSec investigation into the world\u2019s ten largest PFAS producers. According to the nongovernmental organization, almost all of them plan to increase their production or capacity. In company communications, several investments are linked to demand from semiconductors, batteries, cables, cooling and data centers.[1]<\/a>[2]<\/a><\/p>\n\n

Two examples illustrate this trend. In June, Arkema announced a 15% increase in its US capacity for PVDF, a fluoropolymer intended in particular for semiconductors and data center expansion. In August, Chemours launched two refrigerants for stationary chillers and data centers, highlighting their low global warming potential.[5]<\/a>[6]<\/a><\/p>\n\n

These announcements do not, however, show that AI is the sole cause of a global resurgence in PFAS. The same materials are used in electronics, automotive, energy, healthcare and many industrial processes. The most robust finding is narrower: the expansion of AI infrastructure is now one of the commercial arguments used to justify new capacity for fluorinated substances.<\/p>\n\n

\nWhy AI is involved without being the only cause\n <\/h2>\n\n<\/div>\n\n

Large models require accelerators, high-bandwidth networks, memory and cooling systems. As operators build more specialized data centers, demand moves up the entire value chain: extraction and purification of materials, wafer fabrication, photolithography, etching, assembly, cabling and thermal management.<\/p>\n\n

AI\u2019s chemical footprint therefore exists at two levels. It is indirect in the semiconductor fabs that produce the components. It can be more direct in cooling equipment and loops, cables, seals and certain data center fluids. This footprint is less visible than electricity, water or carbon, because operators rarely publish substance inventories that can be compared across sites.<\/p>\n\n

The term PFAS also refers to a very broad family of per- and polyfluoroalkyl substances. Their structure, mobility, toxicity, uses and legal status can differ. Talking about PFAS as if they were a single product therefore leads to overly general conclusions. Conversely, their shared high persistence justifies a family-based approach and particular attention to emissions across the entire life cycle.[3]<\/a>[8]<\/a><\/p>\n\n

\n Plasma etching and deposition\n <\/td>\n\n \n Fluorinated gases used to etch layers or clean process chambers.\n <\/td>\n\n \n Some may not be destroyed. However, fluorinated greenhouse gases and PFAS should not automatically be conflated.\n <\/td>\n <\/tr>\n\n

\n Cables, seals and components\n <\/td>\n\n \n Fluoropolymers providing insulation, chemical resistance and durability.\n <\/td>\n\n \n Emissions can occur mainly during manufacturing, fires, waste treatment or end of life.\n <\/td>\n <\/tr>\n <\/tbody>\n <\/table>\n<\/div>\n\n

The technical inventory published by the Semiconductor Industry Association\u2019s PFAS Consortium confirms this diversity of uses. It is, however, an industry source, produced by companies affected by the proposed restriction. It usefully documents functions and substitution constraints, but does not constitute an independent assessment of their impacts.[3]<\/a><\/p>\n\n

ChemSec is an advocacy organization that campaigns for the replacement of hazardous substances. Its investigation is a relevant source for identifying industrial strategies, but its interpretation must be weighed against company announcements, regulatory data, and environmental measurements. The Guardian adds journalistic work to this, without resolving the main blind spot: the absence of a global public assessment linking production volumes, end uses, and emissions attributable to AI.[1]<\/a>[2]<\/a><\/p>\n\n
