Starbucks and microplastics

The short answer

Two cups, two very different scores, and the gap between them is temperature. The hot paper cup is one of the better-measured exposures in everyday life; the cold cup is one of the less-studied ones.

A paper cup is a plastic cup with a paper exterior — the lining is polyethylene and it releases particles into hot liquid within about fifteen minutes. Ordering the same drink in a ceramic mug costs nothing and removes the lining from the equation.

Frequently Asked Questions

Do Starbucks products contain microplastics?

Two cups, two very different scores, and the gap between them is temperature. The hot paper cup is one of the better-measured exposures in everyday life; the cold cup is one of the less-studied ones. A paper cup is a plastic cup with a paper exterior — the lining is polyethylene and it releases particles into hot liquid within about fifteen minutes. Ordering the same drink in a ceramic mug costs nothing and removes the lining from the equation.

Which Starbucks product is best for microplastics?

Starbucks cold cup, at 42 out of 100 — moderate exposure on evidence grade C, 60% confidence. The highest-scoring is Starbucks hot paper cup at 69.

Is Starbucks a safe brand?

That is not a question this database answers. We score how much plastic contact a product involves, which is a physical property. Safety is a health judgement that depends on evidence nobody currently has, and a brand-level safety verdict would be the least defensible claim on the page.

Does the brand pay to appear here or influence its score?

No. No brand pays for a score, a placement or an ordering, and there is no arrangement that would change one. Scores come from five published components and the components are shown on every product page so a brand can dispute a specific number rather than a vibe. See our methodology page for the full independence policy.
