You are correct, it is technically 100% recyclable. I personally dislike this article because it muddles the message. The whole explanation from the article is that if less than 30% of the material is recycled (in the US), it is not recyclable. I find this a stupid argument, because the material IS recyclable. But for a whole host of reasons in the US, it isn't consistently recycled.
I think this is a good thing. Hopefully it will help people realize that we are using far too much plastic
