Keep in mind that most city's recycling rules are constantly changing.
For example, we had a list up on our refrigerator of what could be put into our blue recycling bin for pick up, which included plastics #1 and #2. But I recently went to the Department of Sanitation website for something else, and found out we can now recycle ALL numbers of recyclable plastics, plus a lot of other things, including some styrofoam. Good to know.

Does your city have a recycling program? I remember the old days of saving newspapers and bringing them to a recycling center. I'm so glad Los Angeles has progressive recycling policies.
