Degradable petro plastics: Your thoughts?

Adding to the confusion of bioplastic definition (see comments on previous bioplastic post) is another growing sector, the development of biodegradable petroleum-based plastics.

I'm sure petroleum-plastics eventually degrade give or take a century or so (maybe even several decades if we're lucky). But brilliant chemists have found ways to make petroleum-based plastics degrade faster - either by combining them with natural-based materials (e.g. polylactic acid, starch, sugar...) or by adding plastic degrading additives.
