How the logistics loop of reusable packaging works

Reusable packaging is only as good as its ability to come back. Between two deliveries, it goes through a chain of operations that does not exist for a single-use cardboard box: collection from the customer, sorting by type and condition, cleaning, then restocking for a new shipment. Each of these stages has a cost, a lead time, and a success rate that is never 100%. Understanding this loop in detail shows where it works well, and where it most often breaks down.

Step one: getting the packaging back from the customer

Everything starts, or fails, at this stage. Without an effective return system, it becomes difficult to reach the rotation rates the model needs to be economically viable. Several solutions coexist in France. Since 2022, the La Poste group (the French postal service) has offered individual returns directly through street post boxes, alongside consolidated return solutions that pool flows for larger volumes. In stores, the country has around 1,000 collection points at retailers, for 13 million packaging units collected in 2023. The choice of return channel, whether pickup point, post box, partner store or dedicated return kiosk, depends more on the customer's existing habits than on the solution that looks most efficient on paper.

Step two: sorting before washing

Returned packaging is not uniform. Some units are clean, others soiled, and some damaged to the point of having to be withdrawn from the loop. Sorting separates these flows before they enter the cleaning line, which avoids contaminating clean batches or needlessly washing containers that will end up being retired. Public funding available for reuse can also cover fitting out a collection vehicle so that clean and dirty containers are separated during the collection round itself, which then makes warehouse sorting and the traceability of each batch easier. Along with cleaning and quality control, sorting is one of the indicators tracked by warehouses that specialize in reuse.

Step three: cleaning, the industrial core of the loop

This is the stage that requires the most investment and the greatest rigor. In France, 69 washing centers processed 12.5 million packaging units, a volume below their combined capacity, estimated at 300 million units per year by industry players quoted in the trade press. This gap reflects less a problem of industrial capacity than a shortfall in volume to process, itself linked to return rates that are still limited.

The washing protocol depends on the original contents. Food packaging requires a different level of hygiene from non-food transport packaging, which led Citeo (France's packaging eco-organization) to publish a specific washing guide for glass packaging intended for food contact, for use by manufacturers and washing service providers. For non-food e-commerce packaging such as the units MOBIUSpack produces, the requirements are different, but the principle remains the same: the cleaning protocol must be defined and controlled, not improvised batch by batch.

Step four: putting the packaging back into circulation

Once washed and inspected, the packaging returns to available stock for a new shipment. In closed loops, between two sites of the same company for example, this return is relatively simple to manage, since routes and volumes are known in advance. Open loops, which involve an end consumer, are more complex: they require an accessible collection system and an incentive strong enough for the customer to take the trouble to bring the packaging back. A pilot run by La Poste with an e-retailer in the cosmetics sector, supported by Citeo, is due to start in September 2026 to test a complete end-to-end chain, from return by the customer through to reconditioning, with two options left to the consumer: dropping the empty container in a dedicated kiosk, or keeping it to return later via a pickup point or a street post box.

The friction points that break the loop

According to several industry analyses, getting the container back remains the hardest part of the whole system, more so than manufacturing it. Three frictions come up regularly in field feedback.

Return lead time matters as much as the final return rate. Packaging that comes back within a week and packaging that comes back after several months do not produce the same loop, even if they end up with the same overall return rate: the latter ties up stock and slows down useful rotations over the year.

A lack of clear incentive makes the system falter. When the customer or the carrier has no concrete reason to bring the packaging back quickly, circulation slows down. This is the whole point of a deposit, covered in another article in this series, as opposed to reuse that relies solely on the customer's goodwill.

Finally, poor visibility of the system explains some of the gaps observed in the field. A study covered by Carenews reports return rates ranging from 1.1% in some retail chains to more than 18% in others, a gap attributed partly to a lack of in-store communication and associated, conversely, with sales staff training at the outlets that achieve the best results.

What this means for operational management

A reuse logistics loop cannot be managed like a one-way flow. Each stage (collection, sorting, cleaning, return to circulation) has its own loss rate and its own cost, and a bottleneck at any one of them is enough to hold back the rest of the chain. Cleaning capacity in France may be more than sufficient, but that capacity is useless if collection does not bring back enough packaging to keep it running. Conversely, a good return rate does not make up for a poorly calibrated cleaning protocol that retires too many units before they have reached their planned number of rotations. It is the chain as a whole, not any single stage, that determines whether the economics of reuse hold up.
