Next, it heads into an enormous vat where it is mixed with water to create ‘slurry’, which is a cool term to define the base materials that paper products come from. First, paper is sorted and washed with a soapy mix to eliminate dirt, dyes, plastic films and staples. Water is a key component to the paper recycling process. Grease or oils from food makes any paper product impossible to recycle. This is because the cheese, grease and food residues soak into the box. But once a pizza drops in that box, it is deemed as “soiled” cardboard. Pizza boxes are commonly made of corrugated cardboard, which is recyclable. But once you learn a little bit more about the paper recycling process, it makes total sense. Obviously, pizza boxes are a pretty common part of the US waste stream, but did you know they are actually NOT recyclable?
That’s a whole lot of pizza boxes!įun fact: Out of the whole US, PENNSYLVANIA has the highest ratio of pizza places per 10,000 people. About 3 billion pizzas are sold each year in the United States.
