Most plastics with the numbers “1” and “2” are recyclable curbside. One common exception is the clamshell containers for fruits and vegetables. Another is plastic bags, which should be returned to stores. Also, if a piece of plastic is “1” or “2,” you may need to remove attached items first (e.g. a soap dispenser pump). It’s always best to check with your locality to see which plastics it wants in recycling bins.
