Most curbside recycling programs in the metro will only take plastic bottles marked with resin code 1 or 2 and "have a neck." I've found this to be a relatively small amount of my recycling. For better or for worse, I go through a lot more sour cream than I do bottled water.
Here are some resources for recycling other types of plastic not usually picked up by curbside recycling:
Plastic Nursery Pots can be dropped off at these local garden centers between April 15th & November 1st.
Plastic Bag collections at local grocery stores sponsored by Minnesota Waste Wise.
Plastics #1 - #6 at the Coon Rapids Recycling Center. You have to sort them yourself, but it's most likely the only place in town to recycle all those plastics not picked up curbside.
NEW: Eastside Co-op is now a pilot program for a city of Minneapolis expanded plastic recycling.
