Why recycle corrugated cardboard?
Corrugated cardboard is an excellent source of fiber for recycling since the material is sturdier, can be easily compacted and baled for cost effective transport to processors, and once pulped can be used to make a wide variety of other end products. Material that can make cardboard difficult to recycle or reduce its value include: wax coating and sticky residue such as book binding, hot glue and melt adhesives, paper labels, laminated adhesive and gum tape.

What about cereal boxes, tissue boxes, toilet paper rolls, and other boxes like that? Should I recycle those?
Short answer: Yes, but...
These type of boxes are NOT corrugated cardboard and although accepted for recycling, are a very low quality/value items. Cereal boxes, tissue boxes, toilet paper rolls, etc. are called paperboard/chipboard. These type of boxes are often made from recycled, pulped and milled corrugated cardboard and are a drastically lower quality material. Due to its less sturdy characteristic chipboard/paperboard are not the most desirable for recycling.
