How biodegradable is PLA plastic?

PLA plastics have come up often as the more eco conscious choice for 3d printed plastics.  With plastics having such a bad rap (petroleum based, some release toxins) I had to look into it a bit more my self.  I searched reprap forums read articles.  This article is the best I found and it covers the perspective of a high volume manufacturer using PLA plastics.  The article doesn't cover any offgases released while processing PLA or when it comes in contact with an object at it's melting point.
