What reusable packaging really costs compared with a single-use cardboard box

A cardboard box costs a few cents. Reusable packaging costs several euros to buy. On that basis alone, the comparison seems settled before it has even begun. It rarely is, because the box is used once while the cost of the reusable unit is spread over several uses, each with its own hidden costs. To make a serious choice between the two, you need to look at the full cost, not the purchase price.

The price of cardboard is simple, but it does not tell the whole story

A standard shipping box costs between €0.25 and €2 per unit depending on size and order volume, with large volumes bringing the unit price down by 25 to 30% compared with buying at retail. But the box alone protects nothing: you have to add void fill, tape, the label and, often forgotten, packing time. E-commerce logistics professionals put the full cost of consumables at between €0.40 and €1.20 per shipment, and up to €1.70 when packing labor is included. These figures remain orders of magnitude taken from commercial sources, to be adjusted to your product and actual volumes.

This cost is incurred once, then it is gone. The box ends up as waste or in recycling at the end of its single trip. No return to organize, no cleaning, no reverse stock to manage. This simplicity has a hidden price: it shifts the cost of end-of-life treatment onto society, and leaves the company with the recurring bill for a purchase that never stops.

The cost of reusable packaging builds up in three stages

Purchase, amortized over several cycles

A reusable crate or mailer costs more to produce than a cardboard box, which makes sense, since it has to withstand dozens of handling operations. This purchase cost is not assessed on its own, but divided by the expected number of rotations. A €5 unit that completes 50 rotations comes to around €0.10 per use for the amortization share alone. If it completes only 10, the calculation changes completely and far exceeds the cost of a cardboard box. The number of rotations actually achieved, not the one announced by the manufacturer, is the variable that drives everything else.

Return logistics, the most frequently underestimated item

Reusable packaging does not come back on its own. Its collection has to be organized, whether through in-store drop-off points, returns built into an existing delivery round, or dedicated return kiosks. The model tested since 2022 by the La Poste group (the French postal service), with individual returns via street post boxes and then consolidated flows for larger volumes, illustrates this range of options and their different costs. An analysis from the logistics sector stresses that returns pay off mainly when they rely on trips that are already being made, rather than on a dedicated round created for the purpose. This is often where a viable model and an unviable one part ways.

Cleaning, an industrial stage in its own right

Washing is not a detail. In France, 69 washing centers have processed and put back on the market 12.5 million packaging units, whereas their combined capacity could reach 300 million units per year according to an industry estimate reported by the trade press. This gap shows that the industrial capacity exists, but that the volumes to be processed remain below what it could handle. Cleaning costs vary widely depending on the type of contents (food or non-food), the packaging material and the distance between the collection point and the washing site, a factor that ADEME (the French agency for ecological transition) explicitly takes into account in its life cycle assessments.

The number of rotations decides the outcome

A French Senate report citing ADEME's work gives a useful picture of the mechanism: a wooden crate used only once a year has, over time, a greater impact than a cardboard box recycled immediately after use. The same principle applies to cost. A Zero Waste Europe study on reusable containers recommends, as part of the upcoming EU packaging regulation (PPWR), a return rate of at least 60% after three years of operation and an average of 10 rotations before end of life within five years. Below these thresholds, the economic advantage of reusable packaging shrinks, sometimes to the point of disappearing.

In France, observed return rates remain highly variable. A pilot covered by Carenews reports rates of 11.9 to 18.6% in some retail networks, 8.4% in pharmacies, and only 1.1% in other chains, with one recurring factor: training sales staff to encourage returns. A deposit scheme monitored over twelve months reaches an average return rate of 24%, a figure industry players consider modest, even though some products such as milk or water exceed 60%.

What ADEME confirms, and what it leaves open

The ADEME study cited by the French Senate (information report No. 850, 2023) on the reuse of glass packaging shows, contrary to a widespread belief, an environmental advantage for reusable packaging that appears from its second use in most of the distribution scenarios tested, with a more gradual advantage (2 to 3 uses) for the hotel, restaurant and café channel alone. The agency is more cautious on two water-related indicators (eutrophication, consumption), where the outcome depends more on washing distance and on the type of secondary packaging used upstream to group units. Cost follows a logic close to that of environmental impact: it depends on effective rotations, washing distance and loss rate, not on any intrinsic virtue of reusable packaging.

How to reason about your own volume

Before comparing two figures, compare two formulas. The cost per use of reusable packaging is obtained by adding the purchase price divided by the realistic number of rotations, the cost of return logistics per cycle, and the cost of cleaning per cycle. This total is then compared with the full cost of the single-use box, consumables and labor included. The break-even point almost always depends on the same three parameters: the actual return rate, the distance between collection and washing, and the volume needed to amortize the investment in the logistics loop itself. Without reliable data on these three points, any claimed percentage of savings should be treated as a working hypothesis, not an established result.
