Recent events led me to look up do microplastics come from dissolving sutures?
Yes, they can; though the plastic is different: polyglycolic acid. Apparently you can get tiny shards as it decomposes, and they worry about cells ingesting them, but that's not what the bulk of the paper above is about.
Microplastics seems a wider topic than I thought.
On a related note, I wonder about the safety of biodegradeable plastics in general. Something that is "starch-based" is partly plastics and partly starch, and it is designed to "break down", i.e., be at least partly digested. But is this a little like soap? Does the digestible part bring the indigestible along with it into the organism? "Here's a little starch to sweeten the taste of the propylene fragment."
