I spotted some water bottles (pictured). I live in the Houston, Texas, area, and found them in my local grocery store.

The website (primabottle.com) says that the bottles are made of 'ingeo' from Natureworks. Interestingly, I have been printing with PLA from Ultimachine, and they say that it is 'ingeo' from Natureworks.

I think that these bottles may be made from PLA!

Now I need to empty one and see if it reacts to heat like the PLA.

OT: fdavies: Sounds like a good idea. I believe recycling is one of the really strong points in favour of RepRap as a production method.
But even though something is made from PLA, how do we know if they mixed in something "nasty", as in something that makes it impossible to use in a RepRap?
