PFAS companies are launching a “tidal wave” of forever chemicals production to meet demand from the AI industry, a campaign organisation has warned.

Despite alarm over the chemicals, which have been linked to cancer, a survey of the 10 biggest manufacturers found most had plans to increase production.

Many frame their investments around the “AI revolution”, because of the role Pfas play in semiconductor production and next-generation datacentre cooling systems.

But opponents warn that the chemicals, which never degrade in nature, are a ticking timebomb for human and planetary health. They say increased production risks undermining nascent moves to restrict Pfas in Europe, the UK and parts of the US.
