Our calculator uses peer-reviewed data and government sources to estimate environmental savings. Here is a detailed explanation of each metric and how we calculate it.
The USDA Forest Service estimates that approximately 17 trees are harvested to produce one ton of new corrugated cardboard. Our formula calculates the weight of cardboard you are reusing (number of boxes multiplied by average box weight) and divides by the per-ton tree usage. This number represents the trees that would have been cut down if those boxes had been manufactured new rather than reused.

Manufacturing new corrugated board is water-intensive. The EPA estimates that producing one ton of virgin corrugated requires approximately 7,000 gallons of water for pulping, washing, forming, and cooling. Our calculator allocates approximately 7 gallons per average-sized box. This water savings compounds significantly at scale: a business reusing 1,000 boxes per month saves roughly 84,000 gallons of water per year.

Each new corrugated box generates approximately 1.3 pounds of CO2 equivalent through its manufacturing lifecycle, including logging, transportation to the mill, pulping energy, board forming, and delivery. By reusing an existing box, you skip this entire manufacturing chain. Our calculator multiplies your box count by 1.3 lbs. For context, preventing 650 lbs of CO2 is equivalent to taking one car off the road for an entire day.

Manufacturing corrugated board from virgin fiber requires approximately 3.5 kWh of energy per box when accounting for logging equipment, transportation, mill operation, drying, cutting, and delivery. Reusing a box requires only a fraction of that energy (inspection, cleaning, and local transport). Our calculator shows the net energy savings, which represents the electrical equivalent of powering about one home for a day per 30 boxes reused.

An average corrugated box occupies approximately 2.5 cubic feet of landfill space when disposed. While cardboard is technically biodegradable, it decomposes slowly in anaerobic landfill conditions and generates methane, a greenhouse gas 25 times more potent than CO2. Reuse keeps boxes out of the waste stream entirely, which is environmentally superior to both landfilling and recycling.

Spending over $2,800 per month on new corrugated boxes for shipping. Boxes were used once and recycled, creating unnecessary waste and cost.
Switched to Grade A and B used boxes from Portland Boxes for 80% of shipments. Kept new boxes only for custom-branded premium orders.
| Metric | Before | After | Impact |
|---|---|---|---|
| Monthly box cost | $2,800 | $1,120 | $1,680/mo |
| Annual savings | $33,600 | $13,440 | $20,160/yr |
| CO2 prevented | 0 lbs | 1,560 lbs/mo | 18,720 lbs/yr |
| Boxes diverted from waste | 0 | 1,200/mo | 14,400/yr |
Wine production and distribution
Purchasing new 12-bottle wine shippers at $3.50 each for tasting room and club shipments. Seasonal volume spikes made inventory planning difficult.
Portland Boxes sources once-used wine shippers from regional distributors and delivers them weekly. Standing order adjusts seasonally.
| Metric | Before | After | Impact |
|---|---|---|---|
| Cost per wine shipper | $3.50 | $1.40 | $2.10/box |
| Annual box spend | $42,000 | $16,800 | $25,200/yr |
| Water saved | 0 gal | 84,000 gal/yr | Equivalent to 4,900 showers |
| Lead time | 2-3 weeks | Same week | Faster fulfillment |
Residential and commercial moving
Buying new boxes for every job and discarding them after a single move. Customers complained about the cost of packing materials added to their moving quote.
Partnered with Portland Boxes for a two-way arrangement: buys used boxes in bulk for moves and sells back boxes collected from customers after unpacking.
| Metric | Before | After | Impact |
|---|---|---|---|
| Box cost per job | $180 | $65 | $115/job |
| Annual savings (400 jobs) | $72,000 | $26,000 | $46,000/yr |
| Customer satisfaction | Neutral | Positive | Eco-friendly appeal |
| Landfill diversion | 0 boxes | 24,000 boxes/yr | 60,000 cu ft saved |

We recommend starting with a trial batch of 50-100 boxes to test the fit, quality, and performance before committing to large volumes. Pack your products, seal the boxes, and run them through your normal shipping process. Verify everything performs as expected.
Most trial orders are delivered within 1-2 business days
Once you are satisfied with quality, establish a recurring order for automatic weekly or monthly delivery. Standing orders lock in pricing, guarantee inventory, and eliminate the time you spend reordering. Adjust quantities with 48 hours notice as your needs change.
Standing orders qualify for our best volume pricing tier
