Break Down Boxes
It’s easier for sanitation workers to handle and sort boxes that are broken down. Make sure to break down your cardboard boxes.
Clean Cardboard Only
Do not recycle cardboard that is wet or contaminated by food residue or grease. You can recycle clean pieces of cardboard by cutting away the soiled pieces.
Remove the Tape Before Recycling
Remove as much tape as possible from cardboard packages. If the package is covered in a paper-backed tape, such as masking tape, the entire package can still be recycled.
Corrugated Cardboard Is Recyclable
All types of cardboard can be recycled except if they’re coated in wax. Recycle corrugated cardboard when possible.
Shiny or Glossy Cardboard Is Recyclable
Shiny or glossy cardboard can be recycled, such as a toothpaste box. Waxed cardboard cannot be recycled, which you can identify by scratching off the wax.
