I am using PLA for 3D printing, and I know it does not degrade well in the wild. I would like to know if there is a chemical process I could use to treat it at home.
Specifically, I am looking for a cleaner alternative than throwing my 3d printing scraps in the garbage, so I wouldn't be generating toxic components when doing this, ideally. I would like the plastic to degrade (in a few years maybe?) when I put it underground while limiting the amount of toxic matter propagating in the soil.
I have read that hydrolyzing PLA could help to achieve this. I also found threads on dissolving it (How to dissolve PLA (polylactic acid)?) But as I am looking for an eco-friendly process, I think I need to stay away from this as the fumes may be very toxic and polluting
Posts like this one Can I really throw failed PLA prints on compost? mention a few requirements for PLA to degrade but doesn't really talk about a way to achieve these conditions.
