Did You Know?
Cardboard is one of the most commonly recycled materials, and two types of cardboard can be recycled: flat cardboard, which is typically used in cereal and shoe boxes, and corrugated cardboard, which has a ruffled layer between the two flat pieces of cardboard and is often used in packing boxes. Both types of cardboard can usually be recycled through your local curbside recycling program. Cardboard that cannot be recycled includes pizza boxes (unless you cut out the food stained portions), cardboard boxes that have not been flattened, and wet boxes.
