What OCC means
OCC stands for old corrugated cardboard, and it is the recycling industry’s grade name for used corrugated collected for re-pulping into new board. When people talk about "cardboard recycling," OCC is the material and the market they mean.
It is one of the most traded recovered materials in the world, with a real, fluctuating price. That price is where a lot of the discipline in recycling comes from.
How a bale gets made
Collected corrugated is fed into a baler that compresses it into dense, wire-bound blocks weighing hundreds of pounds each. Baling makes the material efficient to store and ship — loose cardboard is mostly air, and air is expensive to truck.
A clean, tightly formed bale of dry corrugated is a commodity a mill wants. A loose, contaminated, damp pile is a problem nobody wants to pay for.
What kills bale value
Keeping these out is not fussiness; it is money. Cleaner streams grade higher and sell for more, and heavily contaminated loads can be downgraded or refused.
- Moisture, which adds weight, rots fiber and can be graded as contamination.
- Excess plastic, foam and film mixed in with the board.
- Wax-coated board, which will not re-pulp in the normal stream.
- Heavy food residue and grease that fiber cannot separate from.
“Contamination is the difference between a bale a mill buys and a bale a mill rejects.”
Where reuse fits
Here is the part the recycling story usually leaves out: the best boxes should never reach the baler at all. A sound box baled as OCC is a box that could have shipped again, and re-pulping it burns energy and spends one of the fiber’s limited recycling lives.
That is why we triage for reuse first. Only after a box cannot ship, be reconditioned or be upcycled does it earn a place in the bale. The baler is the bottom of the ladder, not the front door.
The takeaway for your dock
If you generate corrugated, two habits raise the value of what you divert: pull out the genuinely reusable boxes for resale, and keep the rest clean and dry for baling. Both put more money and more fiber back into the loop.
We can handle both ends — buying the reusable boxes and taking the balable remainder — so your corrugated leaves as revenue and diversion rather than as a disposal bill.
