I'm not sure but it seems like biodegradable plastics are easier to degrade by design. Most won't degrade under ambient conditions (since you don't want your spoon dissolving into your soup...), but heat is one of the main ways to accelerate breakdown. I dunno if they might degrade into less-toxic compounds, though.
