Finally, after a little more hunting, I found the website that explained in detail what could be recycled and what could not. Most of the other sites said something like, "you can recycle yogurt cartons!" That just kind of insults a soul's intelligence when you proclaim stuff like that. What if my yogurt carton is lacquered rosewood? Can I recycle that? I need hard facts, people!
Also, there was absolutely no announcement of the fact that type 3-7 plastics was possible since January of last year! That's the most shocking -- there should have been something somewhere to make people aware of this -- at least, make me aware of this!
Fascinating! Here's a video made in August of 2009 (1 month before the Sept. press release) where they say you can't recycle pasteboard (cereal boxes), even though they said you could one month later. This is really, really confusing -- I'm going to have to contact that nice lady with the Waste Watcher program to get some more info on this.
