Paper Straws Are Often Touted as Alternative to Plastic, but They're Toxic

Recent research has raised concerns about the safety of paper straws, which were initially considered a sustainable alternative to plastic straws. A study conducted by researchers from the University of Antwerp found that paper straws contain high levels of perfluoroalkylated and polyfluoroalkylated substances (PFAS), often referred to as "forever chemicals" due to their persistence in the environment. These substances are linked to various health issues, including liver damage, thyroid disease, and cancer. The study analyzed 39 brands of straws made from different materials and discovered that 18 out of 20 paper straw brands tested positive for PFAS. The presence of these chemicals may be due to their accidental inclusion during manufacturing or as a waterproof coating to enhance durability. While stainless steel and glass straws are recommended as safer alternatives, paper straws, despite their eco-friendly marketing, may not be a viable solution to plastic waste due to their toxic content. The findings suggest a need for consumers to reconsider their choices regarding straws and explore more sustainable options.

- Paper straws contain high levels of harmful PFAS chemicals.

- PFAS are linked to serious health issues and are persistent in the environment.

- Stainless steel and glass straws are safer alternatives to paper straws.

- The presence of PFAS in paper straws may be due to manufacturing processes.

- Consumers are encouraged to rethink their use of paper straws as an eco-friendly option.

PFAS, known as "forever chemicals," pose serious health risks and persist in the environment. The EPA has set new drinking water limits, while experts call for stronger regulations and consumer awareness.

PFAs should be illegal in all food applications by now. The danger of PFAs isn't really new at this point. I'm sure if we really try hard we'd find hundreds of viable alternatives (e.g. wax? noodle straws? bamboo?), they just wouldn't have the same margin.

I don't understand people's obsession with straws in general. I prefer my drinks without one – the mouthfeel of a glass is so much better than a straw.

We should just use fucking normal plastic straws. This is environmental priority number 1,000,000, it just appeals to people instead of vastly more impactful interventions because roughly 50% of the environmental movement is looking for minor inconveniences that they can personally endure so they get a feeling of atonement.

There was so many priorities better to spend time on that were actually impactful before we got to “your straw may somehow circumvent the US recycling system and end up in the ocean”

This was just virtue signaling so people could feel better about themselves.

I don’t like how the article recommends stainless steel straws. Those are a great way to cause damage to your teeth/mouth, especially for kids.

Maybe we should treat straws as a wonderful accessibility product that most people shouldn’t use regularly.

If you’ve ever bought a Starbucks iced drink you know that really the only beverage the company sells that needs a straw is a Frappuccino. All those years of selling straws and all Starbucks needed to do was put a properly shaped/size hole on the lid.

Why doesn't this article mention compostable plastic straws?

Some of them are like 90% as good as a regular plastic straws without any of the danger and cleaning annoyance of a metal straw.

Straw Comparison

Stainless Steel Straw - Mass: 15g - Energy: 900 KJ per straw (60GJ per ton of stainless) - Composition: 18% Chromium (Cr) 8% Nickel (Ni) 74% Iron (Fe) - Note: High chromium content, which can be hazardous

Plastic Straw - Mass: 0.5g - Energy: 10 kJ (25MJ/kg for HDPE)

90 reuses needed to break even. Now include the energy for washing and the chance of losing the stainless one. Plastic looks like a winner here.

I'll print a QR code of this on a T-shirt and wear it at every establishment ever that serves you paper straws. They're terrible.

Do not buy anything that requires a straw because the disposable cup you buy is very likely either made of plastic or is lined with bisphenols such as BPA. BPA exposure during pregnancy is even associated with causing permanent neurodevelopmental damage and autism.

Reposting this as a top-level comment because I'd really like to be enlightened.

I truly have not been this confused by the comments on any HN post before and I've been reading this place almost daily for years. Is it completely the default to drink from a straw in the US?

Let's say you're at a business lunch. People drink from straws? I just can't picture it. Or is it because people only order water or alcoholic drinks at such lunches?

Do "fancy" places never serve any carbonated drinks whatsoever? Including something like "artisanal kombucha" or whatever they can ask a premium for? If they do, then are those always served with straws?

I'm seeing reasons like hygiene, lipstick and so on. But I know that even in the US, plenty of people drink wine, and they definitely don't do so with a straw. And places serving wine must have a decent overlap with women wearing lipstick, statistically.

I recently got a bamboo straw in a drink and have to say that worked pretty well and can hopefully be made without pfas; just bamboo.

The study is from 2023. It is not clear why the news article is a year late. The title should note 2023 anyway.

I would really love to see a breakdown on how paper straws came to be. It seems that overnight after that Turtle video a lot of laws were passed, and paper straws (which I had never seen before) were flowing out of every place that sold drinks.

It smells like a premeditated astroturf-driven regulatory capture campaign.

both products are toxic, but one biodegrades and the other doesn't.

> It looked like we had found a solution to our plastic consumption issue... but maybe not

If only there was a way to drink without using a straw

The article suggests stainless steel straws.

Hell, no. All it takes is one trip on something walking out of the coffee shop, using a straw because of sensitive teeth, and I’m possibly dead or paralyzed.

Paralyzed because of a stainless steel straw - all it takes is one time and the public will correctly reject the concept forever.
