Chip Suppliers Warn on EU Plan To Bar 'Forever Chemicals' (ft.com) 64

Chip suppliers have warned that a European effort to impose a ban on "forever chemicals" will cause widespread disruption to already tight semiconductor supply chains. From a report: Five European countries, including Germany and the Netherlands, on Tuesday proposed that the EU phase out tens of thousands of so-called forever chemicals, known as PFAS, used in the production of semiconductors, batteries, aircraft, cars, medical equipment and even frying pans and ski wax.

The ban would constitute "the broadest restriction proposal in history," Frauke Averbeck, who led the proposal for the German Environment Agency, said. "It's a huge step for us to take." Richard Luit, senior policy adviser at the Dutch National Institute for Public Health and Environment, added: "If no action is taken we estimate that the societal costs will exceed the costs without a restriction." However, industry executives warned that a broad ban could have severe consequences for many sectors. Chemours, a leading supplier of high-end fluoropolymers, warned that the chemicals were "absolutely critical" for semiconductor manufacturing as well as a wide range of other industries.

    I understand the desire to ban PFAS chemicals from food containers, because we end up consuming them. I can also maybe understand banning them from things that are likely to go in the garbage dump because of the potential for leaching into the water supply. But banning them from chips that probably won't even be touched by any person, animal, or liquid before they get recycled seems of highly dubious importance. And if chips are ending up in the garbage dump, that's the problem you need to solve, not what the chips are made of.

    Europe screwed over the whole world by forcing their lead-free solder nonsense, and almost two decades later, we're *still* paying the price for that mistake in the form of premature product failures that create mountains of unnecessary e-waste, because even now, lead-free solder breaks way too easily in the real world. And now the EU wants to monkey with chip design again? No. In fact, not just no. H***, no. Maybe even insert a few more swear words into that.

    Find another way to solve the problem — one that doesn't break technology en masse.

        Problems being difficult doesn't mean that they aren't worth solving. The right thing to do is create standards for maximum amounts of these materials that can leach into the water supply, with penalties for failing to do so. The way companies solve that problem should be left up to them. If the easiest solution is to choose a different chemistry for something, and if that has no significant downsides, great. If the easiest solution is to encapsulate the chips in a thin layer of PFAS-free epoxy, that's just as great, because it solves the problem with the least downsides.

            Was the industry even *asked* to solve the problem? AFAIK, nobody was even talking about PFAS as a concern until maybe a year or two ago, or at least that's when I started hearing about it. That's not enough time to come up with a mitigation strategy, implement it, and solve the problem, given the speed of industry. Heck, that's likely not even enough time to pass a regulation saying that they need to solve the problem, given the speed of government.

              They were asked, by the EPA, nearly 20 years ago at this point [epa.gov], because it was already well-known these things were bad news:

              In 2006, EPA invited eight major leading companies in the per- and polyfluoroalkyl substances (PFASs) industry to join in a global stewardship program with two goals:

              • To commit to achieve, no later than 2010, a 95 percent reduction, measured from a year 2000 baseline, in both facility emissions to all media of perfluorooctanoic acid (PFOA), precursor chemicals that can break down to PFOA, and related higher homologue chemicals, and product content levels of these chemicals.
              • To commit to working toward the elimination of these chemicals from emissions and products by 2015.

              And there was some pretty big clues on this well before then; there were investigations back in 1980 when male employees of a textile producer that used PFAS were experiencing impotence and “polymer fever” [theguardian.com]. This isn't new, the news cycle about this was triggered by investigations finding larger amounts of PFAS pollution than expected, and finding that many companies either lied about phasing out PFAS, or while they did actually phase out one specific PFAS (e.g. PFOA), in many cases they did so by just replacing it with some other PFAS (it's a large family of related molecules), adhering to the letter of the EPA rule without adhering to the spirit of the rule.

              You didn't hear about it because it wasn't in the news much, but it was absolutely a big deal for the industry and environment protection organizations. The industry slow-rolled and weaseled out of voluntary compliance, now the hammer comes down.

              • by dgatwood ( 11270 )

                PFOA is *a* PFAS, but it is not the *only* PFAS. Did they fail to achieve the reduction in that specific chemical? No. According to the EPA, all of the companies met the goal as of 2014 [epa.gov].

                So either they lied or asking 8 U.S. companies to be more careful isn't equivalent to setting limits that apply across the entire industry, including internationally.

                Besides, the biggest source of environmental PFAS in waste water is probably Teflon incineration [chemsec.org]. And unfortunately, banning PTFE is probably not technologi

          • It remains to be proven that the semiconductor industry is actually a problem at all. The plastics are used to store and transport harsh chemicals. In the factory. I wish I were wrong but in most applications there is literally no alternative material. You could say it was the invention of these plastics that allowed to industry to exist at all. The plastics are bloody expensive so they are already only used where necessary. The tools also last for decades and none of the PFAS makes it into the final chips.

      There really aren't any PFAs in most chips. However, PFAs are everywhere in the fab. Tubing for the ultra-clean water and most other chemicals, gaskets on vacuum systems, filters for gases and liquids, wafer handling and storage equipment are a few examples.

      Note that PFAS are not a new concern. They are being phased out by manufacturers for years. In my industry we changed chemicals 3 years ago to remove PFOS (a typical member of the PFAS family). Our results in chip manufacture are exactly, exactly the same, according to our experience and to published literature.

      People are once more asking for delays for something we know is a problem, we know how to solve. Same problem with phasing out single-use plastics, or neonicotinoid insecticides. It's your convenience over safety of all, or even the liveability of the ecosystem we need.

      Along the past 2 decades, a bunch of dangerous industrial solvents were progressively phased out and replaced, in particular the chlorinated solvents (tricholoroethane, tricholoroethylene, chloroform), more recently the n-methyl- then the n-ethyl-pyrrolidone. Also chrolobenzene replaced by anisole, and anisole replaced by ethyllactate, amylacetate, other funny-smelling safer solvents. I still have to use dimethylformamide, but we are looking into ways to eliminate it out of the process. We also phased out liquid HF in favour of enclosed vapour HF, much safer for everyone.

      A lot of these solvents used in labs just evaporate to air because of bad quality of lab equipment, careless work, or even because it's less expensive than having them recycled at a specialist waste plant. I don't know where you live, but my pollution from when I was a careless student long ago circled the earth multiple times in the meantime and you and your family members may be breathed it.

      Banning the lead in solder was bad for me as a Sunday hacker because melting temperature of 200 C was more convenient than the new allows that require 300-400 C. I'm nevertheless happy we did it. Lead/cadmium/mercury are a dangerous pollutants and we have electronics waste everywhere in the city. If a single phone that falls off a car to be smashed by traffic is forever pollution in my neighbourhood (and in yours), then I'd rather not have them in the places where the neighbourhood council organize the yearly mushroom picking event.

      Electronics are much cheaper than decades ago, and reliable enough such that we only need change the TV set when it stops being compatible with newer formats, not because they stop working due to soldering.

      We are engineers and we work towards creating new objects that are useful to society. Sometimes we need to rethink design and process to make these objects safer. I'm happy to be part of that.

          The amount anyone will ever be exposed to due to cellphones crushed to dust under car wheels isn't even a rounding error compared to the amount of lead people used to encounter in their environment due to things like paint, leaded gas, or recently-disturbed 19th-century water pipes.

          * Leaded petrol was banned everywhere, starting 20 years ago. Last country in the world still using it was Algeria and they banned it in 2021. The UN congratulated itself over the ban and established a parallel with the Montreal protocol banning the fluorinated refrigerants.
          * Leaded paint was entirely banned in my place between 1988 and 1993. Soma places have regulation to assess and systematically replace leaded paint when houses change owner.
          * Old water pipes are compulsory to replace when lead exceeds 10 ug/L (EU directive from 2013).

          Your examples show that lead was banned step by step, with only corner cases remaining (car batteries). You are using "there is lead century-old pipes" as an excuse to prevent banning lead in 21th Century electronics. That way, you'd never get anything done. Just because there is still some lead circulating somewhere does not mean we should not continue reducing the supply that goes into nature. Eventually we'll get rid of the leaded batteries, and EVs are taking care of that. It does not mean that lead disappears entirely, there will still be corner cases in industry, but not anymore in consumer or disposable products (for example leaded batteries might remain in ton-heavy static storage associated to solar panels).

          Your criticism reminds of people complaining about banning "the plastic straws". It was not the plastic straw, it was the plastics bags, then the straws, then the cutlery, the dishes, coffee cups, most recently the fruit trays, and hopefully one day the fast food hamburger boxes. We're banning things one by one such that industry and consumers have time to adapt to each change. It might take a couple more decades until we're finished, but we're getting there.

          • It's interesting that you mention Britain, because one of the worst residential skyscraper fires in world history - Grenfell Tower - was determined by the authorities to have been ultimately due to an exploding Hotpoint refrigerator that used butane as its refrigerant.

              The Grenfell fire only took this dramatic proportion due to the "calamitous deficiencies in the installation of the windows, cavity barriers and cladding system, and their failure to meet building regulations." Any small scale fire (it's a 24 storey building hosting 300 people, small fires happen) would eventually propagate into a total disaster. It only took 1 year after the "disastrous refurbishment" was completed for a small fire to occur.

              Of course the regulations are designed for those who follow them. Propane as refrigeration fluid is ok as long as fluid installation, and house construction materials, are designed to resist a small fire. Britain chose to improve and banned the combustible insulation panels.

              According to the web, one of the most common cause for fires are still candles. it does not mean we should ban scented candles. What we need to do is to make sure houses are built in a way a candle falling on the ground won't burn down everything.

Until 2021 there was a nationwide obligation in France to oblige the replacement of old insulations, at the occasion of any change on walls and roof operated by any contractor. This was replaced by the new EU energy rating for houses (A+ to G) accompanied by restrictions to sell or rent the worst categories. The city of Paris keeps an obligation to have an inspection, possibly renovation of outer walls once every 10 years.

                  • In most parts of the US, inspectors have no right to demand entry to private property (New York and California might beg to differ). The authorities can refuse to issue a building permit unless you agree to allow inspection, but the whole enforcement system basically depends upon their ability to put noncompliant contractors out of business. If an individual homeowner does work without a permit that isn't visible from a public vantage point, there's very little the authorities can directly DO to them.
