How to Recycle Corrugated Cardboard Boxes Correctly
Corrugated cardboard is one of the most valuable materials collected in curbside recycling programs. To ensure pickup, boxes must be completely emptied, flattened flat, and kept dry inside your recycling cart so truck arms can lift them without jamming.
Review your municipal guide to see if your hauler permits extra flat bundles tied with string beside your cart on high-volume holiday weeks. Always verify your local municipal hauler requirements before placing large items at the curb.
Step-by-Step Instructions
Remove all Styrofoam blocks, bubble wrap, plastic air pillows, and packing peanuts. These items belong in regular trash or specialized drop-off centers.
Slit the bottom and top tape seams with a box cutter so each box folds completely flat. Flattened boxes prevent recycling carts from jamming.
Cut large appliance or furniture boxes into sections no larger than 3 feet by 3 feet so they fit loose inside your wheeled cart with the lid closed.
Place flattened cardboard inside your recycling container with the lid shut. Wet, soggy cardboard breaks down into mush and cannot be processed by sorting screens.
⚠️ Important Rules to Avoid Fines & Hazards
- Do not leave loose, unflattened boxes sitting on the curb next to your cart; automated truck mechanical arms only empty official containers.
- Remove large chunks of plastic foam and heavy shipping plastic before flattening; small amounts of packing tape are acceptable because paper mill pulpers filter tape out.
- Close the cart lid completely on rainy days; wet cardboard loses structural fiber value and turns to pulp prematurely.

Frequently Asked Questions
Do you need to remove packing tape from cardboard boxes?▼
Small strips of clear plastic packing tape or paper tape do not need to be removed. Commercial recycling mills use water tanks and screens that float plastic tape away from paper pulp. However, heavy duct tape and plastic shipping pouches should be pulled off.
What happens if cardboard gets wet from rain?▼
Light surface moisture will dry out, but saturated, soggy cardboard clogs automated sorting machinery at materials recovery facilities and is often diverted to landfills as trash.
Can you put moving boxes out next to your recycling bin?▼
Most haulers require all recycling to fit inside the official cart with the lid closed. Some cities allow extra cardboard tied into 3-foot bundles with sisal twine, but check your local city rules first.
