I posted a link to Real Simple magazine's How to Recycle Anything article a while back, which included items starting with letters A through M. Here's N through Z.
One of the most surprising tips is related to the manila (or "goldenrod") envelopes that are common in offices. They are not recyclable because they (as well as dark or fluorescent paper) are saturated with dyes that are hard to remove. One of the experts quoted in the article, Marti Matsch, says "It's what we call 'designing for the dump,' not the environment." It never occurred to me that dyed paper would be impossible or cost prohibitive to recycle. I'm only going to buy white envelopes and paper from now on.
