If you have read anything else we have written about closed-loop programs, you know we are skeptical of the marketing copy. The math has to work, or the program slowly fails and everyone pretends otherwise for two quarters before unwinding it.
This is one program that worked. We have the customer's permission to publish numbers in aggregate and without naming the brand.
The setup
Co-packer in Pleasant Prairie, Wisconsin. Retail DC in Chicago, 38 road miles south. About 1,200 reconditioned 48×40×36 triple-wall Gaylords shipped each month, returned the following week empty for regrade and re-ship. We standardized on a telescoping-lid format because we knew the boxes were going to take five-plus trips and the lid is what protects the second and third trip.
The 28-month rollup
- Total shipments outbound: 33,684 boxes.
- Total unique boxes used: 6,476 (each averaged ~5.2 trips before retirement).
- Reuse rate over the program: 91% (return rate net of damage and loss).
- Estimated new boxes avoided vs a single-trip baseline: ~27,200.
- Avoided virgin linerboard: ~245 tons.
- Avoided CO₂-eq: ~310,000 lbs (using EPA WARM 2024).
- Net packaging spend reduction vs baseline new-box procurement: 51%.
The parts that surprised us
Three things were not on our original projection.
First, the retail DC receiving team got faster at our cycle than we expected. By month nine they were turning empties in 48 hours instead of the four-day average we planned for. That tightened our cycle-time enough that we needed roughly 18% fewer total boxes in circulation to support the same volume. Good problem.
Second, in month seventeen we saw a 4% spike in damaged returns. It traced back to a forklift driver at the DC who liked to stack three-high during inbound staging. We coached, the driver coached us back on what was making his job hard, we adjusted the lid spec slightly, and the rate dropped back inside a month. The right answer was a small change to the box, not a lecture to the driver.
Third, the carbon-math line item became something the customer's sustainability lead used in board materials. That was not why they signed the program. But it became, two years in, one of the reasons they kept it.
Why we are publishing this
Most yards do not show you the math. The marketing copy you find on most packaging websites — including a lot of ours, honestly — leans on impressive-sounding aggregates without telling you the per-program economics. So you do not know whether the model works at your volume.
This one worked. The route was short, the cycle was tight, the volume was right, and the receiving facility cooperated. We have written elsewhere about programs that did not work and why. Both kinds of stories are useful.
If you are sizing up a closed-loop program and want us to model the math against your real volumes and routes, that is the kind of conversation we like to have. The form on this page goes to a human.
