    I’m not familiar with quilette, but there was a great Washington Post op-ed that broke down exactly why trying to recycle plastic is a bad idea. Here’s a link to it, no paywall: https://wapo.st/3VRnTNl

    1.) Plastic breaks down into micro- and nanoplastic particles and get inhaled or consumed by everybody, and we’re just starting to understand how these bits affect our health (like increased systemic inflammation). Recycling facilities breaking down used plastic release untold amounts of plastic bits into their surrounding environments.

    2.) “Recycling” old plastic into usable material requires the addition of a LOT of brand new, never-recycled plastic. It’s not a process where you put in used plastics and get some amount of usable plastic out, recycled plastic is like 30% old plastic and 70% new plastic to hold it all together. This is a process we’ve been trying to optimize for 50 years, and the improvements are negligible.

    3.) The recycled plastic we get out of it isn’t safe to use for food and drink. (Have you seen those 20 oz. Coke bottles that say “I’m 100% recycled!”? Don’t drink those.) Nobody’s laying down the law and saying they can’t do that, and it’ll be a long time before anyone overcomes the social inertia and corporate lobbyists to stop that from happening.

    Plastics are for landfills. I feel like such a piece of shit every time I throw another piece of plastic in the trash, but it’s the option that’s safest for everybody. (I feel like the French climatologist in Project Hail Mary every time.) Recycling isn’t a goal that will help; we need to adapt and reduce how much plastic we use.

    Not scabies (caused by tiny, parasitic bugs), but scrapie. Scrapie is the sheep form of bovine spongiform encephalopathy, and it’s caused by an abnormal protein in the brain–nothing to do with parasites. The misshapen protein can be found in the brain and spinal cord, and it turns out that grinding animals up wholesale to turn them into meat and bone meal can spread those abnormal proteins to the animals eating their ground up cousins.

    Similar illnesses are found in other animals like elk (chronic wasting disease) and humans (Creutzfeldt-Jakob disease, kuru). If I remember right, spongiform encephalopathies are usually rare conditions that come from gene mutations. That’s why BSE (sensationalized as “mad cow disease”) made headlines 30-40 years ago–these sick sheep and cows were showing up in unexpected numbers because of consuming tainted feed, and there was a lot of uncertainty around whether or not humans could develop CJD from eating tainted beef and mutton. It’s really, really unlikely to happen–the last I’d read about it, the people who were confirmed to have contracted CJD all had a super uncommon genetic quirk that made their normal proteins less able to maintain their healthy shape and increased their risk for disease.
