When 'recyclable' means landfill: what the Starbucks cup tracking study really tells us

Posted on 20.05.2026

If you've ever rinsed out a plastic cup, squinted at the little triangle on the bottom and dropped it confidently in the yellow bin, congratulations: you've been doing what the label asked. Whether that cup actually got recycled is a completely different question — and one a new tracking study out of the United States has just answered in the bluntest way possible.

The US Public Interest Research Group (PIRG) Education Fund slipped Bluetooth trackers into Starbucks cold cups — the clear plastic ones stamped with a resin code and marketed as “widely recyclable” — and followed them from the cafe to wherever they ended up. According to reporting by The Guardian, The Washington Post and Reuters, not a single tracked cup made it to a recycling facility. They went to landfill, to incinerators, or simply to general waste.

That finding is worth sitting with, because it isn't really a story about coffee cups. It's a story about the widening gap between what a product's packaging claims and what the world's waste systems can actually do.

What the trackers actually found

The PIRG investigation, covered by Reuters and the Post, placed GPS trackers in Starbucks cold cups across several US cities and watched where they travelled after being binned. The cups carried Starbucks' own “widely recyclable” designation. None reached a materials recovery facility (MRF) for recycling. Instead, they were routed to landfill or waste-to-energy plants.

Starbucks, for its part, has long marketed the cold cup as a more sustainable option and made public commitments to reduce packaging waste. The Guardian notes that the company labels the cup as recyclable based on the technical properties of the plastic — typically polyethylene terephthalate (PET) or polypropylene. The plastic can be recycled. Whether your local kerbside contractor will actually do it is another matter.

And that distinction — can be versus will be — is where most corporate green claims quietly fall apart.

Why 'recyclable' is a near-meaningless word

In most jurisdictions, calling a product “recyclable” only requires that the material is theoretically capable of being recycled somewhere, by someone, under some set of conditions. It does not require that recycling infrastructure for that item exists at scale where the product is sold.

For a cold cup, several practical hurdles get in the way:

Size and shape. Many MRFs use optical sorters and screens calibrated for bottles and containers of a certain weight and rigidity. Lightweight, flat-walled cups often get misrouted into the paper stream or rejected as contamination.
Contamination. A cup with ice melt, syrup residue and a straw still jammed in the lid is not a clean PET stream. Sorters frequently dump contaminated loads to landfill rather than pay to clean them.
Mixed materials. The cup, lid and straw can be three different resins. Unless a consumer separates them — and most don't — the assembly is functionally unrecyclable.
End-market economics. Even sorted plastic only gets recycled if someone will buy the bales. When virgin plastic is cheap and oil is cheaper still, recyclers can't move the material.

So the cup is recyclable the way a bicycle is “flyable” if you strap it to a rocket. Technically true. Practically irrelevant.

The Australian angle: we've been here before

Australians shouldn't read the PIRG findings as a uniquely American problem. We have our own version of the same story, and we've been living through it since China's National Sword policy in 2018 effectively closed the country to imported recyclables. Council after council quietly began sending sorted recycling to landfill because there was no end market.

The collapse of REDcycle in 2022 — the soft-plastics scheme that Coles and Woolworths customers had been dutifully dropping bread bags and cling wrap into for years — drove the point home. Hundreds of tonnes of carefully separated plastic were sitting in warehouses with nowhere to go. Consumers had done their part. The infrastructure simply didn't exist.

The Australian Competition and Consumer Commission (ACCC) has since put greenwashing squarely in its sights, warning companies that vague environmental claims — “recyclable,” “eco-friendly,” “sustainable” — must be substantiated. The Australasian Recycling Label, with its three-bin pictograms, was designed precisely because “recyclable” on its own had become a marketing word, not an instruction.

Why corporations keep making the claim anyway

If “recyclable” mostly isn't, why does it keep appearing on packaging? Three reasons.

First, it shifts moral responsibility downstream. Once a company can plausibly say its packaging is recyclable, the failure to actually recycle it becomes the consumer's problem, or the council's problem, or the MRF's problem. The brand has discharged its duty at the printing press.

Second, it's cheap. Genuinely redesigning a product for circularity — switching to reusable formats, building deposit-return systems, eliminating mixed-material laminates — costs real money. Updating a label costs almost nothing.

Third, it works. Surveys consistently show consumers will pay a small premium, or at least feel better, about products perceived as environmentally responsible. The reputational dividend from a green label tends to outweigh the reputational risk of being caught out — until, occasionally, a group like PIRG sticks a tracker in a cup.

What actually moves the needle

The Starbucks tracking study is useful not because it proves Starbucks is unusually bad — most quick-service chains would fail the same test — but because it makes the abstract concrete. It forces a more honest question: what does it take to actually close the loop?

A few things have a track record of working:

Container deposit schemes. Every Australian state and territory now has, or is rolling out, a 10-cent refund scheme. Return rates for eligible containers regularly exceed 60-70%, far above kerbside recovery rates for the same items.
Reusable systems. Discount-for-keep-cup programs, hire-and-return cup networks like those trialled in Canberra and Melbourne, and in-store ceramic for dine-in customers all sidestep the question of recyclability entirely.
Extended Producer Responsibility (EPR). Schemes that make brands financially responsible for the end-of-life of their packaging change the calculus. If Starbucks paid the disposal cost of every cup it sold, the cup would get redesigned quickly.
Regulated labelling. Banning unqualified “recyclable” claims and requiring real-world recovery data — as the ACCC and several European regulators are now moving toward — would force claims to match reality.

The takeaway for the person holding the cup

None of this is an argument for cynicism, or for giving up on sorting your bins. Kerbside recycling still works well for some materials — aluminium, steel, clean cardboard, PET bottles — and the system needs participation to function at all. The point is more modest: a recycling symbol on a piece of packaging is a manufacturer's claim, not a guarantee.

The PIRG findings, picked up by The Guardian, the Washington Post and Reuters, are a small empirical puncture in a very large balloon of corporate environmental marketing. Zero out of zero cups reached recycling. The label said otherwise.

If you want to do something with that information, the most useful response isn't to feel guilty about your last iced latte. It's to treat “recyclable” the way you'd treat any other marketing word — with mild scepticism — and to give your custom, where you can, to businesses that have actually built reuse into how they operate. The cup that never gets made is the only one that's guaranteed not to end up in landfill.
