Used paper material collected from the back of factories, supermarkets, and office buildings, and from curbside Blue Box programs and drop-off depots. Paper fibers can be recycled between four and nine times. Any leftover material (corrugated clippings or boxboard trim) is sent back to the mill for recycling. Depending on what type of product it is now carrying, the package ends up at a factory, supermarket, office building, restaurant, hospital (industrial consumers), or in the home (household consumers). These consumers remove the product and now have a decision to make about what to do with the package that got it there: recycle it or put it in the garbage. The material is collected, sorted, and sent to recycling mills to make new packaging. And so, the cycle repeats itself.
