Can Rings and Recycling: What Actually Happens When You Toss Them

Recycling Starts at Home

You just finished a six-pack. You're standing over the recycling bin with the plastic rings in your hand, and you genuinely don't know what to do. Toss them in with the cans? Cut them up first? Throw them in the trash? Most people guess, and most people guess wrong.

It's a small moment, but it repeats itself millions of times a week across the US and Canada, in kitchens, garages, and tailgate parties. The uncertainty isn't your fault. Can rings sit in a strange gap in the recycling system. They're technically made of plastic, but that doesn't mean your curbside bin wants them.

Here's what's actually true, and what you can do about it.

What Are Can Rings Made Of?

Not all can rings are the same material, which is part of why the recycling answer is so confusing.

Flexible film rings, the thin, stretchy kind used on many six-packs, are made from LDPE, plastic #4, the same material as grocery bags and bread bags.

Rigid can carriers, the stiffer, snap-together kind common with craft beer and canned cocktails, are usually made from HDPE #2 or polypropylene #5.

Both are technically plastics that can be recycled in theory. The problem is what happens next.

Can You Put Can Rings in Your Curbside Bin?

Short answer: usually no.

Most municipal recycling programs in the US and Canada aren't equipped to handle either type of can ring in a standard curbside bin.

Flexible film rings are recyclable, but most curbside programs don't accept soft plastic films because they tangle sorting machinery. This is the same reason plastic bags get rejected from your bin. Instead, they typically need to go through a program that specifically accepts low-density polyethylene film, often a store drop-off bin. The US Environmental Protection Agency's recycling guidance notes that plastic film and bags require separate collection from standard single-stream recycling for exactly this reason.

Rigid carriers are frequently marketed as recyclable, but in practice they aren't curbside recyclable in most states, because their material composition and shape make them impractical for single stream sorting systems, even though the plastic itself could be reprocessed in bulk.

A local reporter in Iowa put this exact question to a recycling operator and got a similarly mixed answer: it depends on your municipality, and even where rings are technically accepted, contamination from mixed materials like the bit of nylon used to make them stretchy can disqualify them from standard processing.

The takeaway: don't assume. Check your local program's guidelines before dropping can rings in with your cans and bottles. If in doubt, treat them like plastic film, because that's usually what they are.

Why This Actually Matters Beyond the Bin

This isn't just a sorting inconvenience. When can rings end up in landfills or, worse, the environment, they cause real harm.

They don't break down quickly. Plastic rings can persist in the environment for centuries rather than disappearing.

They're a wildlife hazard. Rings that end up loose in waterways or on beaches can trap birds, fish, and small animals, which is exactly why so many recycling guides recommend cutting every loop open before disposal, so that if a ring does end up loose, no animal can get caught in it. NOAA's Marine Debris Program documents this entanglement risk across hundreds of species, including sea turtles, birds, and marine mammals.

They fragment into microplastics. Even the photodegradable versions don't vanish. They break into smaller pieces that are often eaten by marine life and birds who mistake them for food.

That last point trips a lot of well-meaning people up: photodegradable sounds like biodegradable, but it isn't. It just means the plastic breaks apart faster in sunlight, not that it disappears.

How to Actually Dispose of Can Rings Responsibly

If you have a stack of can rings sitting on your counter right now, here's the realistic order of operations.

Cut every ring before doing anything else. This one habit prevents rings from becoming a wildlife hazard even if they do end up in a landfill.

Check for store drop-off programs. Many grocery stores in the US and Canada that accept plastic bags for recycling will also take clean, dry can rings, since they can typically be dropped off alongside grocery and bread bags where a plastic film recycling bin is available.

Look for manufacturer take-back or mail-in programs. Some ring producers run free return programs that accept rings by mail specifically because standard curbside systems can't process them.

Check if a local brewery or bottle shop takes them back. In several communities, small breweries have started their own reuse programs, taking back clean, stackable can carriers directly from customers to reuse them rather than sending them into the waste stream at all.

If none of the above are available, trash them, cut, not loose. It's not the ideal outcome, but a cut ring in a landfill is far less dangerous than an intact one loose in a waterway.

For Canadian readers: the same logic applies under programs like provincial Blue Box systems. Flexible plastic film, including can rings, is generally excluded from curbside streams for the same sorting contamination reasons as in the US, so store drop-off for plastic film is usually your best bet. Check your municipality's or province's official recycling guide to confirm local rules.

The Bigger Shift: Rethinking the Ring Itself

Recycling instructions only get you so far when the packaging itself wasn't designed with end of life in mind. That's why the more meaningful trend to watch isn't better recycling. It's better materials.

Over the past decade, the beverage industry has been quietly moving away from plastic rings altogether:

In 2010, brewers began developing biodegradable, compostable ring alternatives made from byproducts like wheat and barley, materials that break down naturally and, in some cases, are even safe for wildlife to eat.

In 2018, one major brewer introduced a glue-based system that holds cans together without any plastic rings at all.

By 2023, at least one major beverage company announced plans to shift toward recyclable, paper-based can carriers instead of plastic.

The pattern is clear: the packaging industry is starting to treat what happens after the ring is cut off as a design problem, not just a disposal problem. Paper and fiber-based carriers, in particular, are gaining traction because they fit into recycling and composting systems that already exist, rather than requiring consumers to find a special drop-off point.

Quick Answers: Common Can Ring Questions

Are plastic can rings recyclable? 

Technically, the material is recyclable, but most curbside programs won't accept it. Check for store drop-off or mail-in programs instead.

Should I cut can rings before throwing them away? 

Yes, always. Cutting every loop prevents wildlife entanglement even if the rings end up in a landfill.

Are biodegradable can rings actually better? 

Generally yes. Compostable, fiber-based rings break down without leaving persistent plastic behind and don't fragment into microplastics the way traditional rings do.

Can I recycle can rings in Canada the same way as the US? 

The rules follow the same basic logic. Flexible plastic film is usually excluded from curbside bins in both countries, but always confirm with your local municipality or provincial program, since accepted materials vary by region.

The Real Takeaway

The confusion around can rings isn't a personal failure. It's a packaging design problem that's been quietly pushed onto consumers for decades. Until fiber-based and compostable alternatives fully replace plastic rings industry-wide, the best thing you can do is simple: cut every ring, check your local drop-off options before defaulting to the trash, and support the shift toward packaging that doesn't need a disposal instruction manual in the first place.
