 Pizza boxes

It sounds mighty crazy at first, but it’s true: many cities have adopted the addition of food-soiled paper as yard waste.  Food-soiled paper can include things like kitchen paper towels, cups, plates, napkins, paper take-out cartons, milk cartons, shredded paper, waxed cardboard, food-soiled paper bags, and…. pizza boxes?!  Yes, pizza boxes.  Verify what your waste management company will accept with your yard waste and then throw it in the bin!
