So they say PLA is biodegradable. But I still don't know how much biodegradable.

I live in a flat and we have composting trash can in the courtyard. However if I throw PLA in there and it does not decompose, neighbors are gonna be pissed since many of them are intending to use the soil for their balcony flowers.

So can I really compost PLA, or does "biodegradable" just mean it falls apart eventually, eg. in years? And if it decomposes, is it safe to use for plants?

PLA products will take up to 6 months to degrade in commercial composting facility. In home composting facility, it may take longer time.
