The depreciation nobody books
Sound knocked-down triple-wall containers have real resale value. Left outdoors through one serious rain event, they are worth little more than wet fiber.
No other inventory on a typical site loses that much value that fast, and almost nobody treats it as inventory.
The four rules
All four are free. None requires a project or a capital request.
- Indoors. If that is impossible, under a roof on a pallet with a weighted cover and the edges clear of standing water.
- Flat, collapsed along the original score lines — never folded across a vertical corner.
- Off the floor on a pallet or dunnage, because concrete wicks moisture even when it looks dry.
- Scores aligned, stacks no higher than about sixty inches, away from dock doors and forklift traffic lanes.
Why stack height matters for empties
Flat-stacked corrugated above about sixty inches compresses the scores at the bottom of the stack. Those containers then will not re-erect square, which turns a Grade B unit into a Grade C one without anybody damaging anything.
Two shorter stacks are better than one tall one, and they are also easier to rotate oldest-first.
Rotation and the forgotten pile
Every site that stores empties eventually develops a forgotten pile in a corner: the units at the back that never move, slowly absorbing moisture from the wall behind them.
Mark the stack with the month it was created. Use the oldest first. If a stack has been there more than about six months, either sell it or acknowledge that you are storing fiber rather than containers.
When storage is the wrong answer
If your indoor space is genuinely full, more frequent collection beats worse storage every time. A partial collection costs freight; a ruined stack costs the whole asset value.
Regular scheduled collections help for this reason: empties never accumulate past the point where they have to go outside.
