Is this just because these chemicals are just everywhere? Or are PFAS actually used in the production of straws?

PFAS are used to add a water resistant coating to paper products, so I’d imagine straws to be worse than most paper cutlery as they literally needs to be designed to be submerged in water.

Didn't realize Mountains were pollution until you pointed it out. Thanks for your meaningful and on discussion contribution!

you seem to have interpreted my comment as saying the opposite of what it did in fact say, presumably for humorous effect

Dude drank through too many PFAS-enhanced paper straws and now has reading comprehension problems :(

Do we as a society even need acid drinks?

Do we as a society even need [alcohol|nicotine|cannabis|refined sugar|fat|salt]? Maybe not. But I refuse to believe that you asked that question in good faith, because we're obviously going to have all of them. People should be free to live as healthily or as unhealthily as they choose.

Why? Especially in a country with government-subsidized healthcare?

We have a lot of things that we don’t need. Abundance and option (rather than bare sustenance) are defining features and goals of a healthy society. That’s a long way of saying that there are a lot of things we don’t need, but that eliminating them makes relatively little sense. We should instead develop compensating systems based on those needs (such as disincentivizing single-use straws, and normalizing reusable on…

> Abundance and option (rather than bare sustenance) are defining features and goals of a healthy society… Do you have a source for this claim? It’s not something I’ve read or heard in 36 years.

I think that falls under conventional wisdom.

That sounds unlikely. It's not how stainless steel works; to bond a coating to the surface of the stainless you have to fight the stainlessness pretty hard.

One of the best indicators for not so stainless stainless steel is a coarse texture to aid in that bonding. Even some fairly expensive brands of vacuum flask exhibit this. Only way to be sure that I know of is a knife.

Generally, the easiest way is with a magnet. The most corrosion-resistant of the common stainless steels are austenitic. These steels are not ferromagnetic, or very weakly ferromagnetic if they have been cold worked. Cheaper and less corrosion-resistant ferritic stainless steels are strongly ferromagnetic.

Martensitic stainless steels are less corrosion resistant than austenitic steels and are ferromagnetic, but they're used for good reason. Unlike other types, martensitic steels are hardenable through heat treatment, making them the only suitable choice for many sharp-edged tools or parts subject to severe abrasion. Stainless steel cutlery is most commonly an 18/0 ferritic grade, but premium cutlery may be an 18/10 austenitic. Kitchen knives are invariably martensitic, because ferritic or austenitic grades wouldn't hold a sharp edge.

This smells like astroturfing in favor of plastic. The fact that something contains "traces" of PFAS is not that much of a revelation. Unfortunately, thanks to tragically insufficient environmental regulation, PFAS have gotten everywhere nowadays, so most naturally sourced ingredients will contain traces of PFAS. It is important to know how much PFAS they contain, whether those amounts are higher than the wood feedst…

Which brands? Cant get at the supplementary materials. I bought a set of those IKEA bamboo straws, said to be 100% natural, and indeed I don't see why pfas would be needed on those; solid bamboo.

Bamboo also has its issues [0]. I think mainly because it is kept in shape by bad stuff. Could be that your straws are really 100% bamboo, but some products are something like ground bamboo in some polymer. [0] https://www.europarl.europa.eu/doceo/document/E-9-2020-00064...

The ones I have are just drilled out bamboo sticks (they vary in size and have visible bamboo structure), not reconstituted. I've never seen other types of bamboo straws (everything appears to be paper around here, once I had a pasta-straw), so I'm really curious.

When drinking particularly acid drinks, juice, soda, etc., a straw significantly reduces the amount of erosion of your teeth.

Any link/source? Not that I don’t believe you just curious as it seems plausible but never chances across support for it

To me it doesn’t seem that paper straws is about the resource consumption or oil used or anything like that. I think you have completely misunderstood the purpose. Even with the order of magnitude increase in resources used it’s still insignificant, as you touch on. What’s not insignificant is that in the contexts where straws are used.. fast food and coffee shops and such, they’re all too likely to be just thrown ou…

from my point of view, it depends on how much of it there is and what effect it has on the environment sand, glass, metal, and rust aren't biodegradable either, but i don't think we should ban mountains because they throw sand out into nature when they erode plastic straws are generally polypropylene, which is photodegradable to relatively nontoxic materials

Plastic straws strewn in a natural setting feels a lot worse than sand. I can't tell you exactly why, but I still think that "don't throw plastic around" is a good starting place for a discussion and I don't think it's productive to argue that point.
