- PFAS, or 'Forever Chemicals', are found in all sorts of everyday products, from non-stick pans to stain resistant carpets and fire fighting foams. They're also used to make separator membranes in billions of fuel cells, batteries and other devices. But scientists have discovered that PFAS chemicals can be extremely hazardous to human health, so the race is on to find alternatives. Now a Swedish start-up has perfected a commercial product that could go a long way to achieving that goal.

I certainly do hope you will able to keep balancing the bad news with good news. for our sake. as always 🙏
Yes!...Unless, of course, achieving that balance becomes too strenuous because reality dictates that we start dealing with difficult but necessary truths. In which case I'd like Dave to simply reflect reality accurately - whether that comes across as pessimistic or not.
Dave is a popular and important climate / science communicator and people rely upon him to do the reading for them and present his exquisite summaries accurately. So what he says and the way that he says it, matters. Amongst other things, he helps his viewers calibrate their sense of urgency and that informs some of the decisions they make as citizens. I think he's the kind of guy who worries about striking the right tone and precision in his language.
PFAS firefighting foams are so toxic & pernicious. I'm in Washington State/US, nearby to me a volunteer fire department did some drills with foam & inadvertantly poisoned a local well/ground water area for a development of about 200 homes, PFAS levels off the charts. Now they spend $20,000 a month trucking in water.
Yep our town had to shut down 2 wells due to the same thing at our airport.
Mofos started a RL O'Bannon zombie apocalypse! 😭
Bloody hell,sorry to hear that,what a nightmare.
I lost my faith for humans today. Im a shepard, grazing sheep on pastures. Was trying to read about how and why the price for wool is so low, many shepards use it as compost. Came across not one but 3 separate articles saying how grazing sheep and using their wool for clothes is unethical and destroyers the environment. Then they hade the nerve to instead tell people to use synthetic fleece.
Am I mad or?
You're probably more sane than most.
No. Your not mad. Wool is infamous for being itchy, so most wool clothes like Marino are mixed with other materials like silk and plastic.
Plastic, polyester, became the go-to for fast fashion because it synergizes with Zara, H&Ms business models.
But like I said... Wool is itchy.. and expensive. It lasts long too so it's easy to thrift store shop for a good deal, but you'd have to match it with an undershirt or 3rd piece to avoid the itch.
In Minnesota wool socks area must have in winter. Thank you sheep
Although a lot of places could do with less heavy grazing (by sheep and other ruminants), sheep farming in general is not a bad thing and I agree that wool should be a highly valued product. I think it should be subsidised for applications where it can do the job or else plastics etc. for those applications should be banned (like clothes and insulation), because wool is a very useful product for insulating clothing and buildngs, it's obviously biodegradeable, and as far as I understand (admittedly a layman) it doesn't require a lot of nasty chemicals to process it as some other natural fibres apparently do. I don't think it does the sheep to harvest it either. Plastics on the other hand obviously come with massive costs to people and the environment, costs that aren't paid by the firms selling the products, which is why they are so cheap to buy.
@@nuance9000 Good quality wool (especially Merino) is not itchy. I wear wool socks and wool winter cloths all the time and my suits are woollen, too. Wool is amazing because it lets moisture out, warms you even when wet and is a natural material. People should stop being such pussies and try to buy less, but of good quality, and a lot of the problems we have with plastics and chemicals would go away.
The floating desalination gel pads invented in Korea recently is interesting for small alternative steps to hydrology problems,hopefully it can be environmentally friendly
It’s amazing how little attention is being paid to this problem..!
While this problem goes largely unfunded, millions were spent to breed & raise genetically modified mosquitos in special devices for drone deployment. Right here in the USA 😢
The original goal to decrease numbers of these aggravating but important pollinators hasn't worked. This recent experiment describes "flying vaccinators" 😳
What "messages" have been inserted into the genome of these beings? Who decides if this is a good idea? Is the public aware of this?
They've quit asking if they should, they only care that they can. Seems an inordinate expenditure for dubious reasons.
That is because the Chemical and fossil fuel companies have teams of people in PR department and lobbyist throughout the world governments and media to make sure you hear next to nothing about it. 👍
@@robfer5370Sad but true.
Apart from the EU / ECHA announced plans to ban them not so long ago. They are definitely paying a lot of attention - as are the industries that rely on PFAS. They are in extremely widespread use - because they have unique properties that are extremely useful - making them extremely hard to replace in many applications.
Thank you for the upbeat video, after last week’s downer….I appreciate your efforts to provide balance in weekly presentations (reality and realistic hope). Keep up the superb work! PS: I’m a Minnesota native, for better or worse, and I hope 3M meets their goal.
Incurious readers may be interested to know why you mention Minnesota - _3M_ means _Minnesota Mining & Manufacturing._
Thanks for your feedback. You are so welcome!
@@alanhat5252 maybe due to the fact or possibility that PFAS are contaminating grounds in Minnesota during their production
3M should discontinue producing stuff with the toxins in them *this year.* They are called forever chemicals for a reason.
@@johgude5045 A good idea is always a good idea, however many reasons one may have for them. No need for it to be just one thing.
Thanks, Dave. Interesting video. I recently listened to Martin Scheringer discuss this topic on Nate Hagens' podcast. It was terrifying.
As chemists used to say 'The solution to pollution is dilution'. Until, that is, there are 8 billion of us using these chemicals and dilution becomes very difficult due to the vast quantities of PFAS that we release every day.
One of the reasons ecologists such as William Rees suggest that mankind meets the biological definition of a plague (exponential in our growth in numbers, destructive in our habits, voracious in our appetite for resources and exceeding of our environment's carrying capacity).
Horrible to think of mankind, in all its glory, being described as a plague, but from the perspective of the planet and all other species, that's just what we are.
Let's hope the oil industry does not buy them out.
Thanks for what you do. Great Video!
Why the hate for the oil industry? Doesn't it make your life a lot better?
@@joemccarthy7120it’s not hate, it’s well warranted concern and vigilance. I think we all genuinely appreciate the quality of life we lead due to advances made by that industry. The issue comes with the motive for those companies to block progress away from their industry in an effort to maintain profits and power. It’s been done before and will continue to be done unless we watch them closely, regulate them appropriately and put them back in their place serving the public in the way we want them to.
@@joemccarthy7120 No. They poison people and wreck the climate.
I hope so too!
@joemccarthy7120 the oil industry only looks out for the oil industry. They regularly subdue competition.
Hi Dave:
This is the first video made by you that I have watched. It is informative.
You are also blessed with a clear speaking voice and enunciate your words well.
Best wishes.
This is fascinating. Bamboo grows faster than trees. I can see some pushback against growing trees, or difficulties with trees I can't see any successful arguments against the use of bamboo. That would give us immediate sources of cellulose while the tree-growing happens.
And it'll grow basically anywhere, case in point I have bamboo in my backyard, that I didn'teven plant, and I live in Phoenix desert lol.
@@darthsirriussame here in Cornwall UK
As does Hemp... ;)
The largest part of the world wide wood yield is still simply burnt (the share even went up due to stupid EU definition of wood-combustion as green)
Bamboo is fine, but we have a functioning wood industry (even labour-intensive which is socially good) that can and should be scaled up - we just need to use its yield for the right things.
Build more longtermstructures using wood and the whole industry becomes one CO2-sequestering machine.
Nothing against Bamboo, its of use and can be expanded.
But changing the resources used by an industry is a lot of hassle, and the use of soft- and hardwoods is well established. And sequesters more - since bamboo grows so strong, it puts away far less CO2 per ton than a redwood or a birch.
Everybody hates it but Japanese knotweed seems the ideal biomass plant to me because even a weak electric engine can harvest it (or manually also fast and effortless)
. It is however necessary to kill it (steaming during compression into briquettes ?) before transport so falling pieces of it won't make the plant spread. Perhaps some compression machines can deliver heat too while compressing. The moisture inside the plant would do the rest.
Another great video, thanks Dave.
Cheers Chris. Glad you enjoyed it
In the Netherlands, Chemours (former Du Pont) has been found guilty for knowingly poisoning the area around its factory, dumping PFAS in to the waterways. It's a story which is comparable to the Dark Waters documentry (West Virginia, US). It seems these days that every big chemical and or oil company has some big health issue sceme they're trying to cover up. The faster we swich away from these chemicals and the companies who cover up their health risk, the better. I'm going to swich most of my pans for ceramic pans pretty soon as well.
If you already have coated pans, what's the idea of replacing them? Not buying PFAS products in the first place might be more logical.
@@thirdeye4654coated pans wear out. If they get too hot or scratched, the coating starts leeching into what is cooked on them pretty regularly. I think that's the change @Glassborg was referring to.
I just wanted to note a distinction that you missed: forever chemicals can be made out of trees and flouride. It's just that it's easier to make forever chemicals out of oil than it is to make forever chemicals out of trees.
IMO, the world governments should consider buying out the patent(s) from Cellion and quickly move these new materials (by open-sourcing the technology) for fighting climate change. Human-kind cannot wait for the patent(s) expired before these new materials become a commodity.
Great video. Please keep these coming. So much better than some presenter who tell us what they believe or feel.
Thanks, will do!
"recently"...they have known this "forever". The industry is full of criminals.
This is huge. All pfas is a big problem and the reason that the immune system of people is also affected by it, is terrifying.
I wonder if the nanocellulose can also be used to filter PFAs from solution?
That sounds like worthy research material
Thank you Sir for the hopefully good news. Cheers. :)
Cheers
Being both a waste reduction specialist and a victim of PFAS with a thyroid disease, I am very interested in this subject. Thanks again for such a common sense, straightforward summary with the inclusion of the link to Chemsec and the usual helpful amounts of irony, humour and scepticism. ❤
@@zlmdragon.A paper to start reviewing is _"Thyroid Disrupting Effects of Old and New Generation PFAS"_ by Francesca Coperchini, Laura Croce, and others in the journal Frontiers in Endocrinology (Jan 2021). I'd link it but TH-cam auto-removes links. Searching google scholar for "thyroid PFAS" returned a lot of research on the subject, much of it fairly recent.
Hi Dave, now is it possible to do a piece on Dan Draplin and his hydrothermal autoclave, which apparently, destroys PFAS ?
Tangentially: Why Denmark is sponsoring this research & mitigation initiatives, is we had several nasty run-ins with PFAS.
Such as when cows where pastured *next* to a firefighting training center area and their milk & meat product turned so toxic they really should have been buried in a sealed casket rather sold in local supermarkets. 😓
This sounds like a step in the right direction, unless the trade secrets create a bigger problem than PFAS.
I do hope that this is a good solution, but Freon was a wonder chemical until it wasn't.
Great video, Dave!
Thanks!
Cellulose and acetate rayon have been used in textiles for decades but have largely been replaced by synthetics such as Nylon & Polyester fibers.
If the nano cellulose can be spun or extruded into staple or continuous filament fibers, this would be a game changer.
Would have been great to mention the Film #DarkWaters covering the #DuPont scandal
As per usual, nature has grown the solutions we have but to refine. Love the perspective that the most positively influencial enviromental changes fly under the radar and operate at a "industrial grass roots level" of sorts. Thanks for making these videos!
I recently replaced my Teflon flying pan with a stainless steel one. It took me about 6 months to perfect the process of frying eggs on it without them forming an incredibly had to remove layer at the bottom. It is possible, but requires much more learning...
if anyone is curious, it is mostly down to preheating the pan to the correct temperature. Basically to the point a drop of water 'dances' when put on the hot surface. Nice short here: th-cam.com/users/shortsnWJsY3xQtN0
use clarified butter and turn down the heat
Use an iron skillet, once seasoned it requires little maintenance.
@@AJPemberton That is very interesting. Does it work on aluminium? The only thing I ever use a teflon pan for is egg cooking on my camping stove, because it's such a huge PITA to clean a teflon-free pan.
@@johnmarquez7413Problem is finding a method with neither fat nor PFAS .
My mom died of breast cancer in 2007. She was exposed to DDT in the late 50's from crop dusters. At one point in my life I was so angry I wanted to sue Monsanto out of existence. Now though I feel differently. Yes, they are 100% responsible but that doesn't change the fact the damage has already been done to countless people as well as to life on our planet. I read a book called Silent Spring by Rachael Carson when I was in high school. That opened up my eyes to what corporations were doing in the name of profit. Here we are now with a planet that has been damaged by our hands. I feel now that we are all responsible for our situation and not just a few greedy humans. Anger isn't going to solve our problems but taking responsibility for how we live is. We will have to sacrifice our lifestyle for the greater good and that is why so many people are resistant to the idea. For me it is much easier since I had to go through taking care of my mom and than watching her die slowly a painful death. At some point we will all be suffering and than it will be too late. The one thing I want most now is for people to start caring for each other. I could care less about the f'ing money. Life is way more precious.
Thanks for another great video. This sounds like an excellent alternative to PFAS in things like new battery technologies and water desalination. Now I just hope my own country has a plan for getting rid of PFAS that's as comprehensive as the European one!
Nature indeed has solutions and cellulose based PEM is a great application (well done CellFion) to its ever growing list of biodegrable packaging, plastics, biofuel, pharma-cosmetics,....
Nature is vastly superior to any technology we develop. It's not really a surprise wood can perform this proton separation since (often) trees are built of wood, and trees do this proton separation through photosynthesis for food- making food from the Sun (or eating the Sun if you like).
Another good video I likely wouldn't have heard of without your efforts Dave!
Thank you :-)
Surprised to discover that nature has a 'vastly superior' computer monitor somewhere just waiting to be discovered! And I'll be delighted when natural means of generating and transmitting electricity are put in place.... always disliked the power lines on the streets. :-) I do wonder how we are going to discover a natural and vastly superior option for satellites though?
@@AJPemberton Well, good news for you is plants are expert in Quantum Mechanics and do similar to quantum computing when sending electrons to reaction centers in leaves. The optical cortex is light-years beyond any computer monitor humans have managed, and uses voxels (3D pixels) to compute in higher dimensions. 3D shutter glasses for 3D monitors is an application of this technology developed by a neuroscientist to mimic what Nature invented millions of years ago. Biophysics and Quantum Biology have you covered, and you are in for MANY surprises which will leave you resoundingly humbled.
As for electrical conductivity, the best are electron transport chains in metabolism. The runner-up is graphene, a 2D organic carbon molecular lattice which occurs in Nature and stacks of which form graphite. Copper wires are a hopelessly distant 3rd place, barely woth an honorable mention. As to generating electricity, every biological creature does that. If you disagree, you are welcome to per an Electric eel at your convenience.
As for satellites, the Giant squid has eyes the size of dinner plates and can see anything you can through an 6" telescope in terms of clearly seeing other galaxies like Andromeda. Very simple versions of this are in JWST. instruments like NEAR-CAM and MIRI. And a great many other satellite technologies are found in and invented by Nature.
So yes, you will be surprised and deeply humbled by the technology of nature, of which we can barely mimic in the most simple and embarrassingly childish ways. Most everything we "technology" is merely a clumsy application of an elegant solution we found in nature.
People are not as smart as people think. (The evidence for this I would type, but there aren't enough photons in the Universe.)
@@AJPembertonHumans are part of nature. Any discovery we are making is just something other living things have already discovered and solved. All we are doing is just scaling up those discoveries.
what is actually hysterical is Science is blaming the beginning contributor to Climate Change was the deforestation of the globe... which without WOOD and everything we have used it for from building ships to explore with, to housing, burning for heat, paper for books to educate, clearing lands for food production and cities, and on and on... then we discovered fossil fuels and no longer had to clear cut all the forests... now they want to stop using fossil fuels and start cutting down MORE TREES and collect CO2 and give is Clean Oxygen... GO FIGURE... what might happen? LMAO... they are already converting farmlands into Solar Farms... and the price of FOOD will skyrocket... ALL THIS IS A SCAM TO MAKE MONEY...
It seems one of these PFAS chemicals is polytetrafluoroethylene/PTFE/Teflon!
The stuff is everywhere!
Another excellent episode that covers the really important sustainable solutions that are less glamourous but not less.important. A real education Dave. Well done!
I hope this new alternative rolls out soon. Thank you, Dave.
What I don't understand about this stuff is how it can be poisonous if it doesn't break down in any way. "Does not break down" sounds to my like "inert", does not react with anything. How does it hurt me then?
Good question. Blue asbestos doesn't break down but corses cancer.
I don't know for certain, but smoke and mdf dust are not cancerous chemically, but because of particle size. It is possible for a bit of thing to be so small that it can interfere with your cells mechanically, physically. So, even when this stuff is not chemically active, like not a poison, it might still be an interfering particle, which can get to be a problem if it never breaks down chemically. Ever smaller bits of pfas that just linger for ever, building up, might be the problem, given small particles can interrupt biology when they're small enough.
Type thing...
As I understand it, it's not the reaction, it's the accumulation, and that can cause blockages, places that things can just attach to and grow on, like cancer.
@@petewright4640 Yes, but that is indeed inert and not a chemical reaction but rather a physical response of the body to the fibers. I don't think this is the case with PFAS, it is the fluor in some way.
@@darthsirriusSo it's just mucky shit?
The PFAS problem reminds me of Thomas Midgley, Jr. who gave us leaded gasoline and CFCs. It's been said that no other single human being has done so much damage to our home Planet as he. So, who came up with PFAS? I've long thought that non-stick cookware is a lousy substitute for the simple act of just learning how to cook which takes mere minutes of anyone's time.
You can't 'learn' to make cooked egg proteins not stick to an aluminium pan - they just do. Teflon does make this problem go away. It is of course perfectly possibly to scrape the transformed egg proteins off the pan bottom mechanically, just a pain, and there are other materials that can make a reasonably non-stick surface.
Note that PFAS is not one chemical, it's a big family of them, including Teflon, Goretex (both forms of PTFE), the waterproofing agent in waterproof jackets, things in cosmetics, carpet cleaners and fire-fightitng foam, so there was no one person doing the inventing.
It's not about "learning to cook" . It's about needing to do less cleaning and escaping the need to use excessive grease when frying foods . Non-stick cookware allows dry-frying foods because cinched particles don't glue the crispy surface of the food to the cookware anymore . This allowed new less fatty recipies that will need a different technology now that Teflon is getting banned for a health problem smaller than obesity and clogged arteries .
@@xxwookey I use a cast iron pan and have no problems getting eggs not to stick and stainless steel will also be fine as long as you get the temperature correct. The pan has to be hot enough the the Leidenfrost effect operates
@@PaulG.x OK, but my issue is camping. I'm not going to carry a cast-iron pan up mountains - they are great but bloody heavy. I guess this very-hot stainless scheme could work. This thread is the first I have heard of it. (I saw a video linked below).
I replaced my aluminum camping pots and pans with stainless steel ones ( from MSR ) decades ago for good reasons. They are not really heavy. @@xxwookey
Gracias
feels that there should be mass lawsuits against these companies. from governments, from consumers, from (perhaps a pipedream) shareholders/key stakeholders. the mass damage from PFAS & fossil fuels to the health of all beings is unquestionable. this situation does feel very similar to the fight against the tobacco industry, just far, far, far, far larger an issue for all life everywhere. may the work continue and important questions continue 🙌
Cigarettes cause addiction and cancer. There are no benefits. Fossil fuels have incalculable benefits for all of humanity. The benefits are staggering. You could not get through your day without them. Billions would starve.
Some people die from heart surgery. Should we ban the surgery?
Millions die in car accidents in plane crashes and in ships that sink. Should we ban everything that can harm people? Hospitals are incredibly destructive for the environment, so I guess they've got to go as well.
Rational people embrace the concept of an environmental cost/benefit analysis. Just like when people take dangerous medications.
There should be but won’t.☹️
I worked as an IT contractor for some years at 3M Europe HQ and was impressed by the range of industries they were involved with - one sphere was the health industry where they provided coatings for tablets and the like. I wonder if we have all been swallowing PFAS to make us better?
That aside, you have to admire a company that put old advertising posters for Durex Abrasives (1926 I believe) on the walls
Great video. This is the first time i have head of PFAS.
I now want my nano cellulose frying pan. Soon please.
Whoa! Tony Luongo, the Vancouver Canucks conference winning goalie is subscribed to your Patreon?! Nice save Loooo 🥇
This is a brilliant story of positive human creativity, and humanity balancing up the human, and capital destruction of some country's primitive thirst for more territory.
i wish you called them "pf-ayes" instead but lovely and incredibly informative video as always
Oh, you Americans and your crazy ways of spelling out single letters to make words and designations unrecognizable to the rest of the world .
Subbed! Absolutely genius!
We had a fire in town just a few years ago and they used PFAS foam. This has contaminated many dozens of wells costing our town millions. This issue: it's toxic at jut 20 parts per trillion range.
0:37 that isnt even the full name yet haha, it is Per- and polyfluoroalkyl substances
Also, they are a kind of forever chemicals. Not all forever chemicals are PFAS
Thank you David. 😎
Thank you for such an informative video
Ptfe aka Teflon should never be used in food or clothing or other common place consumer facing applications. That being said there are plenty of industrial applications where there just isn't a suitable replacement and it's incredibly useful if not necessary. As per usual, it's not the material itself, rather how we use it and our entire lack of proper waste management.
Wonderfull. Do we know if the wood substitute is more healthy? Or just the same
The Cellfion site does not mention whether their alternative to PFAS is biodegradable. It would be tragic if these new products were as forever as the PFAS they are intended to replace. Odd that they made no mention of that...
Did you catch the report out of Halifax about battery tape? From what I saw, a bunch of researchers found out that replacing the PET tape in conventional batteries with PP tape would improve battery lifespan as well as self-discharge rate. And all for the same cost as well, which would likely be a no-brainer for manufacturers if proved true.
Great video, thank you very much 👍
Great video, as usual. With the frantic moves that a lot of companies are making to sound and look green and earth along with human friendly (no I didn't make a mistake..earth friendly first and then humanity..as we are the ones who 'voted' to keep these companies going with our politicians pushing them to go higher and faster...sorry I bounced off topic). All these corporate and political moves to get green make me wonder whom or what is behind the curtain that we'll discover down the line that it's not been very good like they kept boasting. Until any company can show how the raw materials come in, get processed into product and then show how they can return 'cast-off' or the garbage created into a proven benign elemental object or produce that could be used to fertilize food that doesn't make us glow now or fifty years down the road, I'm holding back my applause and judgement. I believe it's up to these companies to prove to all of us why we should allow them to keep operating within the same atmosphere we all are in. Politicians are our public servants not the other way around and if they aren't willing to take the slings and arrows that some might fling their way for taking a hard stance on what's good for the public and what's not, then they should stay away from public office. I'd just like to see an idea that covers all processes soup to nuts. Guess I've gotten cynical in my old age after being lied to by the 'next big thing'.
Thanks for your work. I hope you move your content to X soon.
Forestry slash is a huge problem in many parts of the world (parts of New Zealand have been decimated in 2023 because slash hasn't been responsibly removed and processed). It contains a LOT of cellulose. Perhaps forestry companies could be persuaded to see slash as a money-making opportunity, and have it processed to be useful for this. Money for the forestry companies, safer homes and infrastructure for areas that have a lot of local slash and a lot of rain.
If pyrolysis of biomass is fine tuned, I think it could deliver bio fuels which are cheaper than fossil. There would never be enough fuel for all the present cars, so electric would still come first. But there are applications where a combustion engine will still for long be hard to beat. A company seems now able to turn wood lignin into usable jet fuel. Jet fuel is very special, one can't just replace with biodiesel or so..
@@jean-pierredevent970 It has really boggled my mind how much money the NZ forestry industry has turned their noses up at by leaving all that slash just lying there, being wasted. Lack of imagination, I guess.
And it's risky for fires too, I guess, this way?@@r.1599
Thank you for the enlightenment. Stay safe
Forgive me for going into a quiet panic hearing “here’s a new industry that needs trees and trees are renewable”. OMFG, yes, but we are really really shit at renewing trees and staying out of old growth forests too! They only renewable if you actually renew them!!
I picked up a used stainless steel frying pan and i now use it for everything, it doesn't really get stuff stuck to it, as long as it is well lubricated . Never going back to PTFE.
Super!
Worst thing is that even if PFAS is outlawed in Denmark there is a growing trend among farmers to use it in their pesticides. There goes the ground water!
your expression on the call was so much nicer than what we cet in the videos, can we get it in the vids too pls?
I wonder if they can tune the membrane to conduct other cations like Li and Na ions, in, say, batteries. Perhaps such a membrane could also extract Li ions from brines?
Thanks for shedding light on this topic, we are only beginning to understand the negative impacts of PFAS but there is hope just around the corner for a good replacement. If I am not mistaken, these forever chemicals are used to waterproof the paper straws that replace our bad plastic ones?
🤗🙏jpk needed this
One victim of eliminating PFAS is Betacloth - the material that makes spacecuits and covers a large portion of the International Space Station to help regulate temperature. It's great because it's impervious to the rather challenging environment in space, but that is partially due to being impregnated with Teflon. So the company that makes it is phasing it out completely, and NASA and others are scrambling to find and test an acceptable alternative.
After working at a signage company, I became ill. The location was unsanitary, and I developed a terrible rash on my leg that took months to recover. However, given the amount of toxicity to which I was exposed in such a brief period of time, I would not be surprised if I had been exposed to something far more insidious. So many chemicals are contained in signage products alone. Did not even receive protective gloves.
Invicta water.... has the answer. No membranes... that results in accumulation of another waste material to deal with. Invicta Is now gearing up it's chemical process for a residual-free dismantling of PFAS for clear water!!!!!! amazing!!!!!
Putting "forever" chemicals into temporary life forms - what could posssibly go wrong?
I have seen several videos now with green and novel use of wood. Seems to me that every tree has been spoken for three times over. There go our forests.
Good thing they can be sustainably farmed.
@@marvellous9652 at the expense of how much land? How many natural forest has to be cut down to make the room?
@@bzuidgeest In the US, 40% of corn is used to produce ethanol that they then use for gasoline. In Europe, corn is also the #1 resource used to add to gasoline. That land can be freed up as the world moves away from ICE cars.
A lot of land is also currently used to grow livestock feed, which if lab grown meat becomes economically viable in 20 years, opens up a lot of options.
@@marvellous9652 nice try, technically your right about land use, but that assumes several things happening at an pace, that I don't see happening. Ice cars are being replaced, but not that fast. Lab grown meat is in its infancy, it's hardly a viable business at the moment.
As I see it, at best there will be significant overlap where both land uses will be needed. Doubling the land requirements.
I don't mind if you turn out to be right, but I don't see that happening at the moment.
Great video, each presentation we learn a little about science, one day physics another day chemistry, but the main thing every day we learn something about the human being, his ability to destroy is comparable to his genius in innovating.

the best way to get rid of an environmentally sketchy product is to provide a superior product that is more environmentally friendly. sort of like how ceramic and cermet coated cookware seems to last at least twice as long as the equivalently priced teflon coating.
I think Humanity is running into a vicious circle-type of problem: we want durable products that can degrade naturally... Which is literally impossible to do as it won't be durable anymore. It's an oxymoron.
It wasn't precised if this new material was potentially accumulating in the body? If not, I suppose that it is degradable then and so, less long-lasting than PFAS? So the products made from this new material would need to be replaced more frequently?
PFAS is a very serious problem. People get sick from it and don't know it's from PFAS.
Is it not a risk that if we base the replacement of PFAS and PFOS on woodfibres that we're accelerating deforestation? In other words can the necessary fibres be extracted from recycled paper and/or cardboard?
Great news ,.. we have bas pfas contamination here in Minnesota the home of 3m
Amazing
Does a ban on PFAS also affect PTFE? If so, what can be used to replace it?
Technology is fighting with problems created by technology
I don’t like the idea that PFAS chemicals are floating around my bloodstream forever! Let’s keep fingers crossed that nano-cellulose develops as hoped and replaces PFAS ASAP!👍🏻
I would love to get your thoughts on an idea I had after watching a Vox video on building solar panels over existing parking lots to avoid natural habitat loss.
It all depends on Transparent Photovoltaic Solar Panels though, and I can't seem to find very much current information on them. When I first heard about them I thought they would be great for a green house, but I haven't heard anything about them since.
What do you think of a combination Transparent Photovoltaic Solar Panel with a layer of Algae Photobioreactor Cylinders under them? The structures could be built with a water catchment system, maybe even a 'dew collection' system so they don't have to rely on city water. The collected water would be filtered then used in the Algae Cylinders that use the light coming through the panels to grow the Algae. The structures could be set up to collect and refine the algae on site, and could either have it sold offsite to be processed into biofuel/bioplastics or places like big chain grocery stores with their own 'gas' stations could install a structure to process and store the biofuel on site and sell it at their gas station.
This way they could have their own electricity and sell surplus back to the grid for more money, and maybe even offer payment meters for EVs or Van lifers. It would lessen the strain on municipal water in drought effected areas. The more structures are built, the more it would reduce the urban heat island effect as well.
The Algae Cylinders could also function as pollution scrubbers.
Iterations of the structures could be scaled to use on city business buildings and homes as well. It would also work well for rural areas and places like some Native American Reservations that don't have electricity or running water hookups. Each home could have it's own high tech water tower/fuel processor. They could make supplemental income selling the refined algae to be made into various products.
The Power Plants that are currently using algae to scrub their emissions could use these structures and have a sort of closed loop where the sun hits the panels and stores the energy then hits the algae. Then instead of burning coal, they could burn the biofuel they refined themselves to supplement the solar energy, and still cap the CO^2 emissions to feed to the algae. Then every power plant could use this system once it's been proven.
The more of these structures are installed, the more efficient it would be to manufacture Algae biofuel & bioplastics commercially, which is the only argument Big Oil has against it.
If someone smarter than me can design this structure to be built cost effectively and aesthetically, and if we can get the government to subsidize with rebates or tax credits, I really think we can make fossil fuels obsolete.
We would be eliminating the input of fossil fuel based CO^2 into the carbon cycle, replacing it with a product that simultaneously works the same way that needs no consumer retrofitting to begin using and just happens to be carbon neutral since it's already an existing part of the carbon cycle. We'd be mass producing producing air scrubbers. We'd be reducing urban heat island effect. We'd be leaving natural habitats to be utilized for the ecosystems instead of putting up solar farms. All of these changes with one multifunctional, scalable concept would go a very long way to helping offset human induced climate change, and bring equality to basic amenities for underserved communities.
Did I miss the bit where these new membranes are not also "forever chemicals"?
has Cellfion considered using Hemp? Hemp is a sustainable alternative to trees because of its fast growth and regenerative properties.
@3:30 very true 👍
Cast iron pans, not only easy to cook with, easy to clean but they also add iron to your diet which most people are short of. A win, win, win situation.
It’s amazing how much wood is playing a role in our future.
I wonder how wood glass is doing now.
Two things that occurred to me: 1) is there a replacement for firefighting foam? and 2) making it out of cellulose means it's another incentive to cutting down trees, unless we find a real sustainable way to produce cellulose (and no, plant more trees is not a sustainable way, my uncle is a forester... so I know how much time and care goes into planting trees, you're not seeing a real replacement in your lifetime)
Innovationn solves problems.
Dave, did you see the Oct. 4th GeekWire article by Lisa Stiffler: "Forever Chemicals Are Eternal No More"? Sorry I didn't manage to provide the direct link. It's about a new Tacoma, WA startup already in action. (I do not agree that trees are a sustainable alternative raw material. For one thing, trees are already providing huge benefits just by existing. If we become dependent on tree-derived matter, there won't be a tree left on the planet in a decade!)
Dear David, thank you for the next interesting THINK. No matter which solution we are speaking about, the first step of every single implementation must be the change our behavior in a way of REDUCING WASTING with already produced products, materials, solutions, and many more. In INDUSTRY 5.0 we are working now on a project reducing the SINGLE-USE packaging (not only bottles) but all by 90%, which will significantly reduce the volume of "POISON" needed to create these materials and products.
If we do not stop wasting, no matter which material we create it will become an issue on the SUPPLY as on the CONSUMER site as it will create more and more waste.
So, what are the effects of these alternatives in the body
Yay! ❤ _[for the algorithm]_
I certainly did not expect that this particular comment of mine would be the one to be given a...um, creator heart from this particularly thoughtful creator. What did it, the simplicity? The eye-catching emoji drawing the eye in with its splash of color? The square brackets coupled with the italics, as if it were an aside in a play's script? ALL OF THE ABOVE?!?
I don't know, but my heart is lifted for it! Heh, and my verbosity unlocked!
I'm wondering about the claim that "one ton(nne) of pulp produces many thousands of membranes". I should jolly well hope it did, considering how flimsy they are!
Keep waiting
Fuel cells are also called fool cells. And it’s good for keeping scientists and experimental technicians busy for decades.
I wonder how long these membranes can last compared to the forever compound?
This tree thing is amazing. We should manufacture more trees.
