PLA I think just breaks down into lactic acid eventually, but the ABS probably isnt so good
It only breaks down under industrial environments. It's not as "biodegradable" as claimed. I use PETG because I can recycle it with normal plastics recycling.
It breaks down in high heat, high water environments, aka thermophilic composting. This makes it ideal for agricultural and food waste. You're right though it doesn't recycle well.
