You can recycle PLA scraps yourself. The only problem is that devices for this are so expensive that it isn’t worthwhile economically and you likely do not have enough scraps.

you also need to separate your prints properly so that other plastics are not contaminating the scraps.

You also need to buy pellets in order to get a good color.

And also the recycled PLA will probably end up being inferior to the stuff you will buy.

I've seen those - they look like fun projects, but they aren't really a viable solution to 3d printing plastic since not everyone wants to build and learn how to use and maintain one of those, especially since as you say most people won't create enough scrap in the lifetime of their printer to make enough reels to offset the cost+time. What there needs to be is somewhere local that I can take my filament scrap to. But then there's the trust issue: they can't know for sure that my box of scrap contains ONLY PLA, and the consequence of me slipping up and giving them some PETG are pretty high. If PLA recycling were commercially viable to do, I expect it would have been done by now...

Which means PLA is not actually a functionally recyclable or compostable material. Technically, yes. Functionally, no. Which means anything I do on my 3d printer is destined for the landfill, the ocean, the groundwater. Which is why I'm going to avoid 3d printing in the future except when it's absolutely the right tool for the job.
