Amazon says its plastic packaging can be recycled. An investigation finds it usually isn’t.

Wednesday, March 20, 2024

Feeling guilty about all those blue-and-white plastic Amazon bags piling up around the house? Fear not — they can be recycled! At least, that’s what the packaging says. For years now, Amazon’s plastic bags, bubble-lined mailers, and air pillows have featured the ubiquitous “chasing arrows” recycling symbol along with the words “store drop-off.” The idea is simple: Since most curbside recycling programs don’t accept this type of plastic — it’s too expensive to process and can clog machines — consumers can instead leave it at retail stores across the country. From there, this plastic, known as “film,” will go to a specialized facility and be turned into new products. The problem, however, is that the system doesn’t seem to be working. An investigation published Tuesday by the nonprofits Environment America and U.S. Public Interest Research Group, or U.S. PIRG, suggests that only a small fraction of Amazon’s plastic packaging makes it to a material recovery facility, the term for operations that sort glass, metal, plastic, and other items for recycling. The packaging is much more likely to end up in a landfill, incinerator, export terminal, or in the hands of a company that downcycles plastic film into things like benches. The report adds to a growing body of evidence suggesting that store drop-off programs are an ineffective solution to the escalating plastic pollution crisis. According to environmental groups, these programs help justify the ongoing production of single-use plastic, helping manufacturers and retailers evade accountability while alleviating consumer guilt. “The store drop-off system is really not working, and plastic film is not recyclable,” said Jenn Engstrom, state director of U.S. PIRG’s California chapter and a co-author of the report. To find out what happens to Amazon’s plastic packaging, U.S. PIRG and Environment America attached small tracking devices — mostly Apple AirTags — to 93 bundles of Amazon plastic packaging marked for store drop-off and deposited them at retailers in 10 states. These stores, which were listed in an online directory, included mostly supermarkets like Safeway, Sprouts, Publix, Fred Meyer, QFC, and Whole Foods, although some bundles were placed at outlets like Kohl’s or Home Depot.

Of those that survived, 13 went to a landfill, two went to a waste incinerator, and three went to the Port of Los Angeles, suggesting that the bundles were destined for processing or disposal overseas. Only four trackers eventually made their way to a material recovery facility that sorts plastics for recycling. U.S. PIRG and Environment America said they were able to contact three of those facilities: Two specifically said they do not accept Amazon packaging, and the third said it accepts only paper and cardboard. Two dozen trackers ended up in the hands of Trex, a company that makes benches and decking out of discarded plastic. But U.S. PIRG and Environment America question whether Trex is using Amazon packaging in its products; the contents of store drop-off bins are often littered with food and beverages, likely rendering this plastic too contaminated to use in manufacturing. Trex did not respond to Grist’s request for comment, but a similar company reports getting 70 to 80 percent of its plastic from “back-of-the-house shrink wrap,” referring to the material wrapped around shipping pallets, which tends to be cleaner than postconsumer plastic. Meanwhile, a Trex executive told Bloomberg News last year that there is not enough demand for recycled material to make store drop-off successful.  “All the claims the companies are making are just greenwashing,” he told Bloomberg. “Recycling’s failed.” While USPIRG and Environment America’s investigation may be the largest of its kind, it isn’t the first to find flaws in the store drop-off system. Last year, Bloomberg tracked 30 bundles of packaging and wrappers marked with the store drop-off icon and found that 13 of them — more than 40 percent — ended up at U.S. landfills. Just four made it to locations that can recycle plastic. A similar effort from ABC News found that about half of 46 bundles of plastic bags went to landfills and incinerators, while only four went to facilities “that say they are involved with recycling plastic bags.” In 2023, Dell dropped off Amazon plastic packaging (left) at an Albertsons in San Clemente, California. It turned up months later at a warehouse dump pile in Malaysia (right). Photos courtesy of The Last Beach Cleanup. Jan Dell, an independent chemical engineer and founder of the environmental nonprofit The Least Beach Cleanup, has been deploying her own trackers too. Since December 2022, she hasn’t traced a single bundle of film labeled for store drop-off to U.S. facilities that can turn the material into new bags. Twelve bundles have been sent to a landfill or waste station, and one to an incinerator. Four appeared to have traveled to Mexico, Vietnam, or Malaysia, countries that generally lack adequate recycling infrastructure.  “They’re absolutely lying with these labels,” Dell said. The store drop-off system has “never worked, it was never true.”  The labels in question are produced by an initiative called How2Recycle, which began selling them to big companies in 2012 — supposedly to clear up confusion among consumers and retailers about which products could be recycled. The initiative issues several versions of the recycling icon, with the one marked “store drop-off” reserved for products, like plastic bags and film, that aren’t accepted in curbside recycling programs. The store drop-off labels direct consumers to How2Recycle’s website, which links to a directory of retail locations with ]collection receptacles. Until last year, that directory was found at BagandFilmDirectory.org and featured more than 18,000 locations — but the consulting firm managing it shut it down following ABC News’ investigation, citing a lack of “real commitment from the industry,” as well as insufficient funding. Many of the locations listed did not actually have a receptacle, while the Target and Walmart locations appeared to be disposing of, rather than recycling, much of the film they received. “There’s more of an illusion of stuff getting recycled than there actually is because there is an imbalance in supply and demand,” Nina Butler, CEO of the consulting firm, told ABC News. How2Recycle now links customers to a different directory hosted at Earth911. How2Recycle did not respond to Grist’s request for comment. As scrutiny has increased over the use of the store drop-off label, some companies have pledged to stop using it altogether. Mondelez, which owns brands including Oreo and Ritz, said in March 2023, that it plans to phase out the label by 2025. Dell said she’s also noticed the label’s disappearance from packaging sold by Target and Georgia Pacific, a company that sells toilet paper, paper towels, and other pulp products.

When Dell asked the company, during a Zoom meeting in 2020 that she shared with Grist, to provide evidence that the its packaging is widely recycled through the store drop-off program — as required by California law — an Amazon spokesperson told the state recycling commission that the company has “really high confidence that store drop-off is a solution that is available in California.” Pat Lindner, Amazon’s vice president of mechatronics and sustainable packaging, told Grist that the company has no control over how its packaging is handled “once it has been disposed of by municipalities or recycling centers.” A spokesperson said the company is investing in better recycling infrastructure while also reducing plastics use overall. As of last year, for example, Amazon has eliminated plastic from shipments delivered in Europe, likely in response to EU regulations banning several categories of single-use plastic. The company also eliminated plastic packaging in India after Prime Minister Narendra Modi pledged to ban single-use plastic nationwide by 2022. In the U.S. last year, Amazon launched an automated fulfillment center in Euclid, Ohio, that uses paper exclusively instead of plastic packaging, and the company said it’s ramping up a program to ship items in their original packages instead of extra plastic ones. The company also said in a 2022 sustainability report that it was “phasing out padded bags containing plastics in favor of recyclable alternatives,” but the spokesperson did not address Grist’s request to clarify the timeline for this transition. Environmental advocates agree that Amazon has made progress, but say it should be doing more to reduce the hundreds of millions of pounds of single-use plastic trash it generates every year — and that it should remove the How2Recycle symbol from its packaging. In California, where state legislation often sets a national standard, a truth-in-advertising law signed by the governor in 2021 may soon restrict the use of store drop-off labels unless companies can prove that the system is effective. A separate law will require single-use plastic packaging sold in the state to be demonstrably recycled at least 65 percent of the time by 2032, a threshold that may push manufacturers toward paper, which is far easier to recycle.

Trackers placed in 93 bundles of Amazon packaging marked for "store drop-off" recycling showed many of them were buried or burned.

Yeast on Mars could survive, unique new research shows

A new study from scientists in India shows that yeast could survive on Mars, tolerating both shockwaves from impacts and toxic perchlorate salts. The post Yeast on Mars could survive, unique new research shows first appeared on EarthSky.

A new study from researchers in India shows that some of them would be able to. The yeast cells were exposed to high-intensity shockwaves and toxic perchlorate salts in lab tests. Many of them survived. Science matters. Wonder matters. You matter.Join our 2025 Donation Campaign today. Yeast on Mars When it comes to earthly organisms that could conceivably survive on Mars’ harsh surface, the options are seemingly few. But scientists in India found one that just might be able to: yeast. Researchers at the Indian Institute of Science (IISc) and the Physical Research Laboratory (PRL) said on October 24, 2025, that simple yeast cells could survive shockwaves from meteorite impacts and highly toxic perchlorate salts. The research team used simple baker’s yeast (Saccharomyces cerevisiae) for their experiments. Yeasts are tiny, single-celled microorganisms that are classified as part of the fungus kingdom. There are more than 1,500 species currently known. The researchers published their peer-reviewed findings in the journal PNAS Nexus on October 14, 2025. Shockwaves and salts To find out if yeast could actually survive the extreme conditions on Mars, the researchers exposed their yeast samples to two kinds of environmental factors. These were shock waves, mimicking meteorite impacts or marsquakes, and perchlorate salts, which are highly toxic and common on Mars. The shockwaves reached mach 5.6 in intensity. In addition, the researchers exposed the yeast cells to 100 mM sodium perchlorate. This was done both in isolation from the shockwaves and in combination with the shockwaves. These unique experiments had not been done before, explained lead author Riya Dhage, a project assistant at the Indian Institute of Science: One of the biggest hurdles was setting up the HISTA tube to expose live yeast cells to shock waves – something that has not been attempted before – and then recovering yeast with minimum contamination for downstream experiments. What makes this work unique is the integration of shock wave physics and chemical biology with molecular cell biology to probe how life might cope with such Mars-like stressors. Could life survive on Mars? Yeast offers a clue #EarthDotCom #EarthSnap #Earth — Earth.com (@earthdotcom.bsky.social) 2025-10-25T13:25:36Z Yeast on Mars survived in simulations Remarkably, many of the yeast cells did survive. Notably, this was the case whether they were tested with the shockwaves and perchlorates together or separately. The growth of the cells did slow down, but the stressful and toxic conditions didn’t kill them. Co-author Purusharth Rajyaguru said: We were surprised to observe yeast surviving the Mars-like stress conditions that we used in our experiments. We hope that this study will galvanize efforts to have yeast on board in future space explorations. So, how did they survive? The researchers said that ribonucleoprotein (RNP) condensates, produced by the cells, likely saved them. Those are tiny structures that have no membranes. They help protect and reorganize mRNA (messenger RNA) when the cells are under stress. mRNA is a type of single-stranded RNA (ribonucleic acid) involved in protein creation. In fact, the shockwaves triggered the creation of two types of RNPs, called stress granules and P-bodies. The perchlorates, meanwhile, caused the formation of just P-bodies. In some cases, however, the yeast cells weren’t able to form those structures. And consequently, those cells didn’t survive.

Lead author Riya Dhage and co-author Purusharth Rajyaguru at the Indian Institute of Science. Image via Swati Lamba/ Indian Institute of Science. Possible biosignatures The fact that many of the yeast cells did survive was surprising, and shows that similar kinds of cells could indeed survive on Mars in some instances. With that in mind, the protective RNP condensates might actually be good biosignatures – signs of life – when searching for evidence of extraterrestrial lifeforms. Dhage said: What makes this work unique is the integration of shock wave physics and chemical biology with molecular cell biology to probe how life might cope with such Mars-like stressors. Bottom line: A new study from scientists in India shows that yeast could survive on Mars, tolerating both shockwaves from impacts and toxic perchlorate salts.

Why Lung Cancer Is Increasing among Nonsmoking Women Under Age 65

Thoracic surgeon Jonathan Villena explains why early screening for lung cancer is critical—even for those without symptoms.

Rachel Feltman: For Scientific American’s Science Quickly, I’m Rachel Feltman.Lung cancer is the deadliest cancer among women in the United States, surpassing the mortality numbers of breast and ovarian cancer combined. And surprisingly, younger women who have never smoked are increasingly being diagnosed with the disease.Here to explain what could be driving this trend—and why early screening can make all the difference—is Johnathan Villena, a thoracic surgeon at NewYork-Presbyterian and Weill Cornell.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.Thank you so much for joining us.Johnathan Villena: Thank you for having me.Feltman: So our viewers and listeners might be surprised to hear that lung cancer [deaths] in women now tops breast cancer, ovarian cancer combined. Can you tell us more about what’s going on there?Villena: Yeah, definitely. So in general lung cancer is the number-one cancer [killing]people in the U.S., both men and women. If you look at the American Cancer Society, around 226 new—226,000 new cases of lung cancer are projected to be diagnosed in 2025. Of those about 50 percent are cancer-related deaths, meaning [roughly] 120,000 people die every year from lung cancer. Now, what’s—the good news is that the incidence has actually been decreasing in the last few years.Feltman: Mm.Villena: If you look at the American Cancer Society’s statistics, in the last 10 years [ of data, which goes through 2021], the, the incidence of lung cancer has decreased in men around 3 percent per year. And it’s about half of that in women, meaning it’s decreasing [roughly] 1.5 percent per year. So one of the reasons that they think that this might be happening is that there was an uptick in smoking in women around the ’60s and ’70s, and that’s why we’re seeing a slight, you know, decrease in the incidence in men but not so much in the women.What’s more interesting and very surprising is the fact that when you look at younger people, meaning less than 65 years old—especially younger never-smoking people—there’s actually an increase of women in that subgroup. They’re overrepresented, and that’s something very surprising.Feltman: Does the research offer us any clues about what’s going on in this demographic of younger women?Villena: Yeah, so there’s been a lot of research. So, you know, in general—and something that people don’t know is that about 20 percent of lung cancers actually occur in people that have never smoked in their entire lives.Feltman: Mm.Villena: This is something that we don’t really understand why this happens to this one in five people, but there are some risk factors associated with it. Number one is exposure to radon, which is a natural gas that sometimes people are exposed to for a prolonged time. Number two is secondhand smoking ...Feltman: Mm.Villena: So they don’t smoke directly, but they live in a household where they smoke. And number three are kind of other environmental factors, things such as working in a specific, you know, manufacturing plant that deals with specific chemicals. And then lastly, the one that has had, actually, had a lot of research into it are genetic factors. There’s definitely a preponderance of certain mutations in somebody’s genes that can cause lung cancer, and that is overrepresented in women.Feltman: Do women face any unique challenges in getting diagnosed or treated when it comes to lung cancer?Villena: So, yes. First of all, you know, how do we treat or catch lung cancer? So the newest and, and latest way of catching this disease is actually through lung cancer screening.That’s something that’s relatively new; it’s only happened in the last 10 years. And that’s in certain demographics, meaning that if someone is over 50 years old and they have smoked more than one pack per day for 20 years, they meet the criteria for lung cancer screening, which is basically a radiograph or a CAT scan of their lungs. That’s the way that we pick up lung cancer.That’s the—almost the exact same thing that people have for breast cancer, such as mammography, or colonoscopy. So that’s before any symptoms come in. That’s really just to try to capture it when it’s in very nascent stages, right?Feltman: Mm-hmm.Villena: Where it’s very small or not symptomatic. And that’s the way we diagnose a, a lot of lung cancer.Now, that being said, there’s a couple of things. So first of all, [roughly] 60 to 70 percent of people, like, in general get mammographies.Feltman: Mm-hmm.Villena: [About] 60 to 70 percent of people get colonoscopies. Only 6 percent of people actually get lung cancer screening. So it’s dismally low.Feltman: Yeah.Villena: The reason being that sometimes people don’t know about it; it’s relatively new. Sometimes even doctors don’t know about it. There’s also a little bit of guilt involved, where people, you know, they think they did it to themselves by smoking ...Feltman: Hmm.Villena: So they don’t wanna go do it. The second thing is that, as you could imagine, this is only for high-risk individuals or people that have a history of smoking, all right? So it misses these never-smoking one in five patients. So that’s one of the things that we’re actively working on.Feltman: Yeah, how else does the, you know, the stigma associated with lung cancer because of its association with smoking, how does that impact people’s ability to get diagnosed and treated?Villena: I think there’s a lot of hesitancy between patients. There’s, you know, a recent study that showed that people are more—have more tendency to downplay their smoking history, meaning that if they quit, let’s say 10 years ago, you tell your doctor that you never smoked.Feltman: Mm.Villena: And that’s something very common. Or if you smoked, you know, one pack a day, maybe you say you smoked half a pack a day because you feel that guilt. So then you don’t give your doctor or your caretaker the full picture. And sometimes that prevents you from getting these tests, right? So there’s definitely that attitude.There’s also a bit of a fatalistic attitude, sort of like, “I did it to myself. I’d rather not know. You know, this is something that—you know, I made that choice, and if I get cancer, that’s my choice.” Right? So that’s, that’s also another attitude that we’re constantly trying to change in patients. You know, the treatment, once you capture it, is all the same, but really it’s about getting screening and it’s about finding the lung cancer.Feltman: So with smoking no longer necessarily being the driving factor, at least in this younger demographic, what kinds of risk factors should we be talking about more?Villena: So I think, you know—so smoking is always number one.Feltman: Sure.Villena: In the never-smoking people it’s either radon, secondhand smoking or environmental factors, and then a little bit of genetics plays, plays a part.Radon is something that people can test for in their homes. It’s something that people should read up on. So that’s number one: if you have exposure to that, to get rid of that.If you are in, in an environment, let’s say you work with chemicals that you think, you know, are astringent or have caused—causes you to have coughs or, you know, affects you in any sort of way, to kind of try to talk to your employer to work in a more ventilated setting.Really important with genetic factors is understanding your family history.Feltman: Mm.Villena: If you have a mother, a grandmother, a grandfather who died of cancer or you have a lot of cancer in your family, sometimes understanding that and knowing that from your, you know, from your family perspective will actually clue a doctor in to doing further tests, to looking into that further, ’cause that sometimes is passed down and you can have the same genes.Feltman: Are there any big research questions that scientists need to answer about lung cancer, specifically in young women?Villena: So, you know, there’s so much to look at, all right? So if we think about just the genetic aspect of it, there’s one specific gene called the EGFR gene—or it’s a mutation that’s found in lung cancer that in, if you look at all people with lung cancer, it’s found in about 15 percent ...Feltman: Mm-hmm.Villena: Of the population with lung cancer. Now, if you look at never-smoking Asian women that get lung cancer, it’s about 60 percent of them ...Feltman: Mm.Villena: Have that mutation. So the important thing about that EGFR mutation is there’s a specific drug for that mutation, all right?So there’s definitely a lot of genetic kind of information that we’re still actively researching. But the important thing about this genetic information is that there’s drugs targeted specifically for those mutations. So the more we know, the more we understand, the better.Feltman: So for folks who are hearing this and are surprised and, and maybe concerned what is your advice for how they should proceed, how they should look into their risk factors?Villena: You know, I think one of the, the, the major aspects of health in general is understanding your own health.Feltman: Mm.Villena: I think that younger people tend to delay care, tend to not see their doctors, and because, one, they’re busy, right, at their very busy moment in their lives. But second is that, you know, you don’t wanna deal with it, and you think that you will not get cancer, that you will not get this disease because you’re young and you’ve never smoked and you’ve never done anything bad.Feltman: Mm.Villena: But, you know, you have to be very aware of your body, so what are the kind of top four symptoms? So number one, let’s say you have a cough, and that cough lasts for longer than two weeks, right?Feltman: Mm-hmm.Villena: A normal cold, things like that will go away after a couple of weeks. But if it’s there for a couple of months, and I’ve definitely seen patients that tell me in retrospect, you know, “I’ve had this cough for three months,” right, and it should have been checked up sooner. So understanding yourself, understanding your body, not, you know, waiting for things, not procrastinating, which is very hard to do, but you should definitely see your doctor ...Feltman: Yeah.Villena: Regularly.Second is, like I said before, understanding your family, right, and what your genetic makeup is, right? Knowing your family history, understanding if your parents, grandparents had cancer, etcetera, or other chronic diseases.Feltman: Mm-hmm.Villena: And that’s, that’s basically the, the major aspects of it. It’s really being in tune with yourself.Feltman: So once a patient is actually diagnosed, what does treatment look like?Villena: So treatment for lung cancer, actually, is heavily dependent on the stage. There’s everything from stage 1, in which it’s localized to one portion of a lung, to stage 4, where it actually has gone to other parts of the body.Now, stage 1 disease, you basically need a simple surgery, where that lung nodule, or that lung cancer, is surgically removed, and typically you don’t need any other treatments. So stage 1 is what we look for. Stage 1 is the reason that lung cancer screening works because stage 1 doesn’t really have any symptoms ...Feltman: Mm.Villena: So when you find it that early patients do very well.Stage 4, once it’s left the lung, you are no longer a surgical candidate, unless in, you know, sometimes very specific cases, but for the most part you’re no longer a surgical candidate. And there you need systemic treatments.Feltman: And how long does the treatment tend to take for a stage 1 patient, if it’s just a surgical procedure?Villena: So if it’s just a surgical procedure, look, I do these surgeries all the time: the patient comes in; we do the surgery; the patients usually go home the next day.Feltman: Wow.Villena: And then we follow the patient and get CAT scans every six months for a long time to make sure nothing comes back or nothing new comes. So it’s pretty straightforward, and we do this all the time. We do these surgeries robotically now. Patients recover incredibly well, and they’re out, you know, doing—living their lives in a couple of weeks. So it’s really something very, very, very efficient.Feltman: Yeah, so huge incentive to get checked early.Villena: Mm-hmm.Feltman: Are there any advances in treatment, you know, any new treatments that doctors are excited about?Villena: Yeah, so there’s two major steps forward that have changed lung cancer treatment. Number one is something called targeted therapy.Feltman: Mm-hmm.Villena: So that means that there’s a drug that targets a specific mutation. So just how I was speaking about earlier about the EGFR mutation in young, never-smoking Asian women, there is a drug that targets that mutation that has really shown amazing results at all stages now.And the second one is actually immunotherapy, which won the Nobel Prize, which is this idea that you can use your own body’s immune system to kill the cancer cell. So cancer is very smart—what it does is it evades your immune system; it pretends that it’s part of your own body. And what this drug does is that it basically reawakens your immune system to recognize that cancer again and kill it. And we’ve seen amazing results, even in the stage 4 patients, where they are potentially cured of cancer, which, which we’ve never seen before.Feltman: What motivated you to get into this specialty?Villena: You know, I do have a family history of this in an uncle that passed away from lung cancer ...Feltman: Mm.Villena: And he was a heavy smoker. And, you know, I saw how, basically, decimated his, he was—[his] life [was], basically. He was a very vibrant guy, he was very active, and in six months he was gone, right?And I think, you know, once I started getting into, you know, medical school and understanding things, one of the major things that I really got into was research. And I see that if my uncle had been treated 20 years ago, he potentially could have been saved ...Feltman: Mm.Villena: Because of these advances in research. And right now we are right at the cusp where we are learning all these new things, and we actually have the tools to change how patients are treated, you know? And this—every year there’s a new treatment, which prior to that, there was no new treatment; i t was basically just chemo, and that’s it, all right? So I think that that really motivated me—something that I can actually take part in and actually change the course for a lot of people.Feltman: Well, thank you so much for coming on to chat with us today. This has been great.Villena: Thank you.Feltman: That’s all for today’s episode.

California Gov. Gavin Newsom (D) vetoed a bill that would have banned the use of “forever chemicals” in cookware and other products in California. The bill became a source of controversy in the Golden State, with celebrity chefs among those who rallied against the cookware ban, while environmental and health activists have argued for it. It would have blocked the sales of cleaning products, dental floss, children's products, food packaging and ski wax that contained such chemicals starting in 2028 and cookware with them starting in 2030. While the bans would have only applied in California, the state’s sheer size gives it significant influence over what gets manufactured for sale across the nation. Newsom, in his veto message Monday, raised concerns about the availability of affordable cookware if the ban were to be implemented. “The broad range of products that would be impacted by this bill would result in a sizable and rapid shift in cooking products available to Californians,” the likely 2028 presidential hopeful wrote. “I appreciate efforts to protect the health and safety of consumers, and while this bill is well-intentioned, I am deeply concerned about the impact this bill would have on the availability of affordable options,” he added. However, proponents of the bill say the veto will result in more exposure to toxic chemicals.  “By vetoing SB 682, Governor Newsom failed to protect Californians and our drinking water from toxic forever chemicals,” said Anna Reade, director of PFAS advocacy with the Natural Resources Defense Council, in a written statement.  “It’s unfortunate that misinformation and greed by some in the cookware industry tanked this policy,”  Reade added. Forever chemicals are the nickname of a group of chemicals called PFAS that have been used in a wide variety of everyday products, including those that are nonstick or waterproof. Exposure to them has been linked to prostate, kidney and testicular cancer, as well as immune system and fertility issues.  They can persist for decades in the environment instead of breaking down and have become pervasive in U.S. waterways, tap water and human beings. California has historically been a relatively aggressive state in terms of environmental and product regulations — for example, requiring that products containing certain chemicals contain warning labels. However, several other states have already banned PFAS in cookware and other products.
