      Those reusable grocery bags made from recycled plastic? Disintegrates into dust eventually. And in your household to while it does so.

      And on the other hand, growing cotton uses a lot of water. And wool comes from animals.

        Cotton and wool can at least be returned to the earth naturally. Cotton can be grown places where water shortages aren’t an issue.

        Personally the greenest option for me is trying to buy clothing made from nature textiles at a second hang store. I also wear what I own until it is basically rags, if a garmet gets a hole or a stain it becomes work clothing for when I’m doing dirty work. Obviously everyone on the planet cannot do that, but as it stands we already waste tons of clothing with fast fashion and many garmets are only worn a handful of timea before being thrown away or even never worn or sold at all before becoming trash.

        Someone already suggested hemp, but there is also other fibres like linen.

        At the end of the day clothing would not be an issue at all, if clothes were made to last and worn accordingly. Unless you work in blue collar jobs, the wear on clothes is minimal and there is no reason why a set of shirts shouldn’t last you a decade.

    Lots of things contribute to this. Vehicle weight (extra stress on the tires), wheel alignment (toe-in/out causes scrubbing which causes more wear), unmaintained suspensions (worn out shocks, struts and bushings causing the above), burnouts (obviously, but, even in winter being the guy doing a burnout on summer tires while trying to get up an icy hill or across the intersection still counts), tire compound, road design, and driving style. If we had more cargo trains doing logi instead of long haul trucks we could probably cut down on a lot of pollution both in exhaust particles and tire particles.

      I can’t imagine much microplatics are getting chipped off of them. The tires have thousands of pounds of pressure being put on small surface areas when you round corners, where as a plastic bottleneck can dolphin into the water if hit by a large wave and not nearly as much friction placed on it.

      How I imagine it

        so plastic floating in a salty ocean, being hit with wave after wave of hundreds if not thousands of tons of pressure 24 hours a day 7 days a week for literal decades all while slamming into other plastic bottles will release less plastic than tires?

        IDK. I think a wider study should be done.

        50-75 trillion pieces of plastic exist in the ocean today and makes up 80% of all marine pollution.

        plastic itself isn’t easily recycled either. tires on vehicles can be reliably recycled into other products like asphalt, roof shingles, new tires, etc.

        I think if the concern is about microplastics, there are bigger pollutants at hand that need attention before car tires.

          One question that’d be interesting to know the answer to is where it ends up at. I could imagine microplastics from the garbage island mostly staying around the island, whereas ones from tires will end up all over the environment.

      Unfortunately this is known since two decades or so. I have learned about it in Uni 5 years ago.

      I expect that car and tire manufacturers have been lobbying against this getting more attention extensively. There is no other solution except reducing car traffic.

        We are far from good: Cars ruined walkability. Most suburbs are under constant tyre roar within a kilometer from a freeway. Stroads are hideous and biking there is dangerous.

        Tyre dust went onto fields, into crops, we ate the dust, gut illness became common. Heard of gluten free? People are sick.

    While there’s no doubt tires are bad for the environment, a quarter of all microplastics seems a lot, especially since plastic is everywhere. Gladly there’s a source for that claim, a link to tireindustryproject’s FAQ… Claiming that this number is a gross overestimation. What the fuck is this article? Is it supposed to be satire or something?

      I’ve seen a similar number in a lot of proper scientific sources, so this article may be bunk, but the number is correct I think.

      For example this article: https://doi.org/10.1016/j.scitotenv.2024.171003 They claim 27,26% in China.

      And this article: https://www.rivm.nl/bibliotheek/rapporten/2024-0106.pdf They claim 24.88% in the EU and state it’s among the biggest if not the biggest contributor to microplastics.

      I’m all for debunking stuff, but about a quarter seems to be the currently accepted quantity to the best of our abilities to measure.

      There is a bit of confusion between the amount tyres contribute into the ocean, how much into the ocean and waterways and how much in the environment as a whole. A lot of it ends up in the soil, so it doesn’t contribute to plastics in the water, but still in the environment.

        That was an interesting read. I guess tyre fragments (and industrial pellets) are just way bigger than the other big offenders, which would explain why they represent such a huge portion of the total mass, and why they are filtered out “easily”. Overall it seems to me that we really need to categorize the different microplastics better, as the current definition (anything plastic 5mm and under) seems a bit too large, and with all the mix ups, you can always blame something else.

      Bear in mind that the denominator is plastic pollution. Most plastic waste does not directly pollute the environment. If it is not recycled then it goes to landfills or incineration. Not ideal, but at least the damage is contained. (The bulk of ocean plastic comes from the rivers of poor countries without proper waste management.)

      The issue with tyre microplastics is that it’s all but impossible to channel the waste. It’s the same with synthetic fabric: just washing it creates pollution that’s really hard to control.

          Yes the washer wastewater should be easy in theory. But to filter the really small particles you’d need an expensive HEPA-equivalent filter that has to be regularly changed. Needless to say, none of this is happening in practice.

          Filtering tyre dust is always going to be a haphazard proposition. This interesting contraption notwithstanding.

        (The bulk of ocean plastic comes from the rivers of poor countries without proper waste management.)

        This might be true for places nearer to shore, but studies have found the great Pacific patch to be mostly discarded fishing gear by weight.

          Yes I’ve seen this factoid too, but I struggle to see how it could be true. We’re comparing theoretically non-disposable kit from individual boats with the output of a large number of massive rivers in countries with populations of hundreds of millions (in particular Indonesia and Philippines) and a terrible habit of dumping trash in waterways. The amount reaching the ocean must by definition be huge.

          Of course, the main problem with discarded fishing nets is not that they are plastic but that they destroy the ecosystem by design. Maybe the two harms have been conflated.

            I also struggle with it, but the research I’ve seen is that it’s the majority by weight. Microplastics wouldn’t get picked up, so they’d be really hard to be weighed.

            Then again, these big pieces will be shedding microplastics all the time so maybe they’re contributing to it as well.

            Either way, we’ve got two problems: Plastic runoff from rivers and fishing gear disposal. And both, I think, could be solved by simply providing cash for people who can verifiably dispose of plastics. Check out some nets and floats and line, check in a certain amount and you get money back. Because people are greedy and stupid we need to incentivize cleaning things up.

      This is so far from the truth.

      The real reason is cars are heavier. The more weight, the more wear on the tires. You can only make a tire compound so hard before they become uncomfortable rolling chunks.

      In the 70s when the fuel crisis hit, cars were very inefficient. Heavy steel and heavy engines that guzzled field. As the technology has progressed we use composite materials to make them lighter where we can. Some of these materials are more expensive than others, so you won’t find them on all models. Magnesium and Carbon fiber for example. We started to make cars lighter.

      Then there’s features, creature comforts, etc. We started adding more and more fancy features over time. These all add up. Heavy sound deadening pads are placed all over the bare chassis. Rip up your car’s carpet, underneath you’ll find them. They’re in the door and behind the dashboard. There’s even foam in the A, B and C pillars. We figured out that we can make cars quieter. Now that we can make them quieter, let’s add a lot of creature comforts. Power, heated seats and mirrors. Power windows, powered lift gates, and anything else that’s powered. These require electric motors. Not sure if you’ve ever seen these electric motors, but these are actually quite heavy little things. A few speakers is now almost a dozen in many models. Lots of trim pieces that make the car more aesthetically pleasing add weight.

      Safety is a huge factor as well. One or two airbags has turned into about a dozen. Extra beams that are used to dissipate energy around you in a crash. My car has 8 alone for just the front driver and passenger.

      Got a hybrid or an EV? These absolutely demolish tires because the additional components adds a lot of weight.

      Even though we got better at making composite materials and reducing weight where we could, our need for creature comforts and advancement in technology has caused the overall trend for a car’s weight to go up. This information is readily available if you’d like to search the Internet.

      A set of tires wear endurance has only gone up over time. But because of a car’s weight, it reduces its ability. Your driving habits also greatly impact how long your tires will last. Do you have a Rivian or Tesla? Go easy on the acceleration and showing off with the spirited driving. You can make your tires last less than 10,000 mi. Do you add additional weight? How long is that additional weight being hauled around? In other words, if your trunk is full of stuff, clean it out. You’re increasing fuel consumption and increasing tire wear.

          Given that Gore actually won the election it’s arguable that his concessions towards climate change, that it was real for a start, was the reason the election was close enough for him to lose the election. Voters loved the comforting lie over the hard truth then and they still do.

          Especially given the yahoo Trump wants to appoint that doesn’t believe in climate change even in 2024 is pretty damning of our ability to do anything about it.

          So you’re absolving “Generation Me” of ever having to think for themselves? The same generation that could have educated themselves for less than the price of new car, and simply chose not to because a high school diploma was enough?

          Millennials were just as heavily, if not more propagandized, and yet, as a cohort, we have skewed far from Baby Boomers (ie Millenials are killing x), while retaining the ability to be critical of the systems we have inherited. We are also far more educated and far more in debt. All as a result of Boomers subsidizing their own welfare on the backs of their children and grandchildren.

          Baby Boomers collectively failed upward, soaked up benefit after benefit while telling themselves that they deserved their station in life, and then pulled up every ladder behind them.

          So, hard disagree.

They chose to remain ignorant and uneducated, and when they gained any advantage, they made sure that those who came afterward would NOT. That’s not just a lack of awareness, it’s mean-spirited and selfish. Which fits “Generation Me,” to a T.

        Bikes cause thousands of times less damage to streets so I wouldn’t be surprised if they also wear less.

          The wear rate should be proportional to the weight of the system (car plus cargo and passsengers, bike plus cargo and riders), maybe with some correction factors for things that affect wear rate like knobbiness.

          Since bikes weigh a couple orders of magnitude less on average, the amount of tire wear material should also be a couple orders of magnitude less.

          Edit: other lemmyer said wear is proportional to weight to the 4th power and that may be correct. I vaguely recall that from school now that they mentioned it.

      Yes, imagine if there was a fast and safe way of transport. Something like made to run on steel bars in order to reduce friction. I don’t know. I’m just imagining, I watch too much science fiction.

        I imagine it’s still orders of magnitudes better than everyone driving their own car in.

        Same with busses. Don’t let perfect be the enemy of the good

          Technically, a subway would be easier to build a microplastic containment solution than applying the same to endless miles of roadway. Using metal wheels is probably still the better option though

            subways are only economical in big cities though.

            No one is building a subway in my town, would be waaaaay to expensive. they couldnt even keep a tram system going

    This is also yet another reason SUVs are bad: bigger tyres, higher weight, more wear, more pollution.

    It’s also another reason to have lower speed limits: less friction, less wear, less pollution.

      You want trains because they are good for the environment.

      I learned recently that speed limits are determined by studying the speeds driven and setting them at the 85th percentile.

      So what we can do to lower speed limits is to find a place they’re doing a traffic study and repeatedly drive over them at very low speeds.
