What is paperboard? Can I recycle it with cardboard?
Check the edge—paperboard items have one layer, while cardboard items have three layers (including a middle wavy layer). Examples of paperboard items are cracker boxes and toilet paper tubes. Some programs (such as the Pinellas County Utilities drop-off centers) accept paperboard and cardboard mixed together, but other programs require the items to be separated (such as the Largo curbside program requests that cardboard be placed under the bin).
