How refill stores are changing the way we reduce waste

Refilling a bottle instead of throwing it away has become a popular way for people to reduce waste — a small, tangible action in response to larger environmental problems.

But whether refilling actually makes a difference depends on how these systems are used and what they replace. Scores of refill stores have opened in recent years as retailers and customers seek fresh ways to reduce waste. Some brands are also using specialized recycling programs for tricky packaging.

At Lufka Refillable Zero Waste store in Tampa, customers bring in reusable containers to fill with soap, shampoo and cleaning supplies instead of buying products in single-use packaging. The idea is to cut down on packaging waste by reusing what people already own.

Customers' containers are weighed first, then filled. They're charged by the amount of product added. Over time, that reuse can add up.

For customer Julie Hughes, the act of refilling feels rewarding. Hughes discovered Lufka two years ago while looking for skincare products and has returned regularly, drawn by the ability to reuse packaging rather than discard it.

''When you do something positive, you get a little bit of like a dopamine hit and you feel good,'' Hughes said on a recent trip to buy liquid hand soap. ''There are so many big problems in the world, but we can't solve all of the big problems, but we do have control over our choices.''

Some shoppers have been refilling the same containers for six years, said Lufka founder Kelly Hawaii.

A new spin on old packaging systems

Refillable packaging is less a new invention than a return to earlier distribution models. Many industries historically relied on refillable or returnable containers, with familiar examples in the U.S. including soda, beer and dairy in the recent past.

A 2020 study of reusable packaging explains that a shift to single-use packaging took hold mainly because disposable systems simplified logistics and reduced handling costs for producers and retailers. That transition contributed to a steady increase in packaging production and waste over time as reuse infrastructure declined, according to the study published in Resources, Conservation & Recycling: X.

In recent years, there has been a renewed interest in reuse as part of a broader move toward a ''circular economy'' that keeps products and materials in use longer to limit waste. The Public Interest Research Group estimates there are hundreds of refillable stores around the country, part of what it calls a ''generation of new businesses'' aimed at reducing packaging waste.

Larger chains and brands are also offering refillable options and other innovations. Lush Cosmetics sells certain products ''naked,'' without packaging, and offers discounts to customers who return containers from its other products. The reusable packaging platform Loop, available in France, partners with major brands such as Nestle and Coca-Cola to distribute products in durable containers that are collected, cleaned and refilled for reuse.

The ‘payback period' for reusable containers

Reusing vessels for everyday products has advantages over recycling single-use packages, as long as people follow a thoughtful approach, according to experts.

Shelie Miller, a University of Michigan professor who studies sustainability, said consumers should think of the phrase ''reduce, reuse, recycle'' as a priority order, meaning reuse should generally come before recycling.

Still, reuse doesn't automatically mean lower environmental impact. Durable reusable containers typically require more energy and materials to produce, so they need to be used long enough to offset the resources that go into them, Miller said. What this means is that the environmental advantage emerges only after repeated use spreads those initial impacts across many uses, which Miller refers to as a ''payback period.'' How much water and electricity consumers use at home to clean reusable products also factors in.

A 2021 study by Miller and a colleague examined reusable products including drinking straws, forks and coffee cups and measured their payback periods in separate categories including greenhouse gas emissions, water use and energy demand. The study found that a ceramic coffee mug must be reused between 4 and 32 times before outperforming disposable cups on those measures, which represented faster paybacks than reusable coffee cups made from metal or plastic.

''If you are making dedicated trips just to reduce packaging, it actually can be worse for the environment than if you use the single-use product,'' said Miller.

Handling hard-to-recycle items

Large beauty retailers such as Ulta Beauty and Sephora are also partnering with Pact Collective, a nonprofit that collects hard-to-recycle beauty packaging through in-store bins.

Carly Snider, executive director of Pact Collective, said the program collects packaging made of mixed materials that regular recycling programs can't process or small pieces measuring less than 2 inches (5 centimeters) — like pumps, droppers and sample-sized containers — that fall through the cracks of machines at recycling facilities.

''There's specific things with beauty packaging that makes it really difficult,'' said Snider.

Experts emphasize that refilling and recycling programs aren't a perfect solution, but when they replace single-use packaging and fit into everyday life, they can help reduce waste.

''Small things do add up,'' Miller said. ''And so when you have millions of people who are all doing small things, that really can make a difference, make a change.''
