Cardboard tubes help keep you clean, neat, safe and organized, from kitchen to bathroom, craft room to workshop. Recycling cardboard tubes is as straight forward as you’d expect. When the last sheet is gone, it’s ready for the blue bin. Cardboard tubes are in your craft supplies too, often as cores for wrapping paper or fabric. Flattening is purely optional! Did you recently receive a painting or poster? Just be sure to remove the plastic end caps and recycle them, either alongside the cardboard tube or in separate bins, depending on your neighborhood streams!
