out of envelopes before you put it in your paper recycles or do you leave it in? This bugs me EVERY week, lol. Who does this and who doesn't . Anyone know how they deal with the plastic. ?
It IS possible to remove those windows during the recycling process but the process is not foolproof. Staples and other metal are easier to remove from the recycling stream. Remove the windows, if you can, but don't worry about it. Most of the paper will become newsprint, cardboard, or insulation and a bit of contamination is unimportant.
If your recycler says they take Mixed paper or mail, then don't worry about the windows. They are prepared to deal with the windows.
You're supposed to break them out because it's not possible for them to mechanically sort them out. Some recyclers will chop it up into flakes which can then be sorted but that brings it's own problems.
