When Loop launched at Davos in January 2019, with Procter & Gamble, Nestlé, PepsiCo, Unilever, and Mondelēz lined up on stage, the pitch was simple and total: durable, branded containers shipped to your door, returned in a tote bag, cleaned, refilled, and shipped again. The bin shrinks. The problem is solved.
The bin did not shrink. But something real did emerge from all of it, just not where most people went looking.
If you’ve ever bought a Loop product at Tesco, refilled a shampoo bottle in a bulk store, or signed up for a returnable-deposit detergent service and quietly given up after one cycle, you are the typical refill consumer in 2026. That is not an indictment of you. It is an indictment of a category that spent half a decade selling the wrong version of itself.
The 2019 Vision Ran Into the 2022 Cost-of-Living Crisis
Tesco’s Loop trial ran for nine months across ten stores in the UK before ending in June 2022. Customers purchased more than 80,000 Loop products across the trial, a number the program described as “encouraging” and that Tesco’s responsible sourcing director, in his post-mortem blog, described as a fraction of what would justify continuing.
Tom Szaky, TerraCycle’s CEO, has been candid about what happened. The UK absorbed Brexit, COVID, and the Ukraine war in rapid succession. The cost-of-living crisis hit just as Loop was preparing to move from pilot to national rollout. Without a deposit law or a shelf-space mandate forcing the equation, the consumer math doesn’t close: the deposit is annoying, the return trip is annoying, and the price premium is real.
Meanwhile, the Ellen MacArthur Foundation’s 2025 progress report found that reuse among brand and retail signatories remained near 1.2% of packaging portfolios, even as the same companies reached roughly 16% post-consumer recycled content. The refill economy didn’t collapse. It stalled, at scale, in unregulated markets. Those are different problems.
Where Refill Works: Four Categories Doing Real Volume
The categories that actually work share one structural feature: the consumer doesn’t have to close a logistics loop.
Concentrated cleaning. Blueland’s tablets, Grove Collaborative’s refill pods, and Cleancult’s milk-carton concentrates win on a physics argument: roughly 90% of conventional household cleaner is water, heavy, expensive to ship, and identical to what comes out of your tap. Strip the water, ship a tablet or a pouch, and the carbon and cost math swings hard in the refill’s favor. The consumer keeps a durable bottle, refills it with tap water, and the reverse logistics problem disappears entirely. This is the cleanest unit economics story in the category, clean enough to earn shelf space at Target, Walmart, and Amazon.

Premium beauty and fragrance. The keeper-and-refill model (durable outer container, lightweight inner refill) works here because the margin structure supports the operational complexity of a refill SKU. Lancôme’s refillable Génifique Ultimate reportedly uses significantly less glass and primary packaging than the standard format, with savings compounding across refill cycles. Kjaer Weis built its luxury cosmetics line around refillable metal compacts from the beginning. Hermès, Chanel, Hourglass, and the broader L’Oréal portfolio have all shipped serious refill systems in the past three years. The customer who buys premium skincare values the bottle as an object. The refill cap is a feature, not a friction.

In-store refill where infrastructure already exists. France is the clearest case study. The country’s AGEC anti-waste law and the EU’s Packaging and Packaging Waste Regulation set hard reuse mandates, and Loop now operates returnable products across hundreds of Carrefour, Monoprix, and Système U stores. Carrefour prices reusable formats lower than disposable. That is a regulated market doing what unregulated markets won’t. In the US, the working examples are narrower but real: REI’s bulk fluid stations for sunscreen and bug spray, Plaine Products at participating retailers, the bulk aisles at chains like Sprouts and Whole Foods. 
The common factor is that the consumer is already in the store. No shipping. No return logistics. No deposit dance.
DTC keeper-plus-refill subscription. MUD\WTR sells a starter tin and ships refill pouches via subscription. Ritual does the same for vitamins. This isn’t refill in the Ellen MacArthur Foundation sense, but it works: the brand owns the customer relationship, the refill is meaningfully lighter than a new container, and the subscription cadence handles the friction the consumer would otherwise have to manage.
Where Refill Doesn’t Work Yet
Mass-market reusable shipping in unregulated markets. Loop’s original vision has not commercially scaled outside France and Japan, both of which have regulatory backstops. Without a deposit law, an EPR fee, or a shelf-space mandate, the consumer math doesn’t close.
Mass-market grocery. Tesco’s post-mortem said the quiet part out loud: 80,000 Loop products across 10 stores over nine months is a rounding error in a national supply chain. Packaging is a tiny share of a $4 box of cereal, and most consumers won’t absorb the inconvenience of returning containers for a category they don’t think about.
Anything that requires the consumer to sterilize at home. Pilots that required home cleaning before refill have failed across nearly every category they’ve been tried in. The hygiene anxiety alone kills it; the actual labor finishes the job.
A Practical Refill Playbook for 2026
Five categories worth your time, ranked by how forgiving they are of a busy life:
- Hand soap. One refill concentrate pouch fills your existing dispenser six to eight times. Lowest-friction starting point.
<!-- AFFILIATE: Blueland, Grove, Public Goods --> - Dish soap. Same logic, same brands. Concentrate plus tap water in your existing bottle.
- All-purpose cleaning sprays. Refill tablets dropped into a reusable spray bottle. The category where the math is most lopsided in your favor.
- A premium skincare product you’re already loyal to. If the brand sells a refill SKU, switch on your next reorder: typically 10–15% cheaper, identical formula.
<!-- AFFILIATE: Lancôme, Kjaer Weis, Hourglass --> - Shampoo or body wash, but only if a participating in-store refill station is on a route you already drive. If it isn’t, skip it: shipping refillable shampoo round-trip rarely pencils out.
What to skip: mass-market reusable shipping schemes that ask for deposits, careful container handling, and a courier pickup window. Wait for these to be either regulated into existence (the EU is doing this) or rebuilt around real retail infrastructure. Don’t pay the early-adopter tax on a model that may not exist in three years.
“The refill economy is structural, not moral. If a system isn’t built for your week, the answer isn’t to try harder — it’s to refill where the system actually works.”
What’s Coming
Three trends are concrete enough to plan around.
EU regulation will keep pulling the refill ecosystem forward. The PPWR’s reuse targets for beverages, takeaway, and e-commerce kick in over the next several years and will force retailers to build the infrastructure consumers in unregulated markets aren’t asking for yet. Some of that infrastructure will eventually be ported to the US by the same retailers operating in both markets.
Premium beauty refill will keep expanding. The unit economics are too good for brands not to build the SKU, and Sephora and Ulta are merchandising the format more aggressively than they were two years ago.
More DTC subscription brands will default to a keeper-plus-refill model, not as a sustainability feature, but because the shipping math favors it.
What you should not expect: a return of the all-in-one reusable shipping vision in the US without federal or state regulatory action. That bet has been made and tested. The next refill economy looks more like a French grocery aisle and a $90 serum than a tote bag full of glass jars on your doorstep.
That’s a more honest story than the one told at Davos in 2019. And the parts that work: they work every week, without the early-adopter tax.
If you want more of this, the honest version of what’s working and what isn’t in sustainable retail, stick around.
