  • We need more alternatives to plastic, not the same number or fewer. Why wouldn’t we make sustainable materials from waste streams to replace the environmentally harmful ones that we banned ten years ago? Your preferences are one person’s preferences. You’re free to continue using apricot scrubs and baby oil, nobody’s trying to take them away from you. However, I would really like to find an environmentally sound, no-fossil-source, physical exfoliant with greater uniformity than the ones you like. (As an aside, milled pits, seeds, and shells (like nut shells) aren’t good exfoliants for human skin. They’re effective scrubbers, but the milling process leaves a lot of points and jagged edges in the resulting product which causes small tears in the skin barrier, reducing its ability to keep your insides safe from the outside.)

    It kind of sounds like you’re neglecting the need for continuing innovation in materials science and engineering. We’re not just talking about replacing the horrific plastic microbeads in cosmetics, we’re talking about doing the work to develop entirely new materials that could potentially be used across a wide range of industries. Relying on pits and shells is definitely not the way forward here when we could be developing replacements for plastic wrap and styrofoam using stuff like food waste, fungi, and seaweeds.


  • Starch is a polymer. Cellulose is a polymer. Chitosan is a polymer, as is chitin. They’re just materials made of long chain, repeating units. One of the ways we can “fix plastic” is by making materials that have similar properties out of naturally-derived stuff that has nothing to do with fossil sources, like plants, arthropod shells, and fungi. We leave a LOT of possibilities just lying around in food production waste streams. This is exactly the same as “replacing plastic,” and the only real difference is which version writers like to use in their articles.









  • It probably is still legal, but it’s not something I’ve looked for in like a decade. We do have products that use ground kernels, but those aren’t good to use on skin–the milling process doesn’t produce uniform particles and the pointy bits tend to compromise the barrier skin provides with very small tears.

    I completely agree that plastic isn’t necessary for good soap, I just like it. I would definitely buy soap made with ecologically responsible plantstic at least once.

    More importantly, using safer, scalable, completely biodegradable, algae-based polymers opens up so many more options for single-use products while simultaneously improving environmental quality. Farming algae and seaweeds removes a lot of contaminants from the ocean, like agricultural fertilizer and solid waste runoff. If we can truly scale up ocean farming responsibly, it’ll be its own “teal cascade” in which the benefits multiply with each step in the process.

    1. Farming algae/seaweed doesn’t require the use of inorganic fertilizers when you grow them alongside shellfish like oysters, clams, and scallops

    2. Increased protein production through shellfish reduces reliance on agricultural livestock for meat (which is incredibly damaging to the environment)

    3. Algae/seaweed can replace fossil carbon in fertilizers and plastics, and reduces cattle methane emissions by 20% or more when added to their regular feed

    At each step, we can take more and more petroleum out of the equation just by using methods that are better than sustainable, they actually remediate existing harm.

    Plus, I get my scrubby soap back.







  • The failure was in supplying nitrogen to an array of 16 freezers. Unless samples were split and stored in different arrays without the same coolant source, they’d still have lost everything.

    It would be easy enough to create multiple sample sets to be stored that way, but it’d add an extra variable researchers would need to account and test for in their work as well as reducing sample capacity by at least half. A place as mighty and prestigious as the Karolinska Institute probably has a ton of graduate researchers, too, and everybody knows those people just graduate and leave all their shit behind without clearing out old samples.

    The whole thing is heartbreaking.
