Cardboard Put in Recycling Cart/Bin Do not put whole boxes in your recycling cart. Cut large boxes small enough to fit loosely inside the recycling cart. Any cardboard that doesn’t fit in your cart can be broken down into pieces no larger than 4′ by 4′ and leaned against your recycling cart for pickup. Shiny or glossy cardboard can be recycled, such as a toothpaste box. Tape, glue and other adhesives are OK. Any additional packaging such as expanded polystyrene, twist ties, bubble wrap or air pillows need to be removed from cardboard packaging and put in the garbage. Waxed cardboard, which you can identify by scratching off the wax, also cannot be recycled along with boxes stained with grease or oil. These go in the garbage cart. If you have moving boxes that are in good condition, consider donating them. Did You Know? Going Flat: Good or Bad? Check out this short cartoon for a tip on how to recycle cardboard. Cardboard Recycling About 70 percent of commercial shipping boxes that are made out of cardboard will be recycled. To be recycled, boxes are first turned into pulp, and then the fibers are separated and bleached. After these fibers are screened, they are washed, pressed and then rolled into paper.
