Does Nespresso Original aluminium capsule have microplastics?
The short answer
Substantially less than a plastic pod. The capsule body is aluminium, so there is no polymer wall for hot pressurised water to pass along — only a thin internal lacquer. That is a real improvement, and it is a lacquer question rather than a particle-free claim.
Why Nespresso Original aluminium capsule scores 30
Aluminium body — the polymer wall that defines the plastic-pod problem is simply absent
A thin internal lacquer still separates the coffee from the metal
Hot water under high pressure, which is unchanged from any capsule system
Puncturing creates cut edges in metal and lacquer rather than in bulk plastic
Where the 30 comes from
Five components, added. The page renders the parts rather than a stored total, so the number cannot disagree with the reasoning behind it.

What material touches the contents, over how much surface area, for how long. Glass and steel score near zero here; a film pressed against fatty food scores near the top.
Heat, abrasion, flexing, repeated opening, reuse beyond design life. The same bottle scores differently in a fridge and in a hot car.
What a laboratory actually counted, for this product or its category. A high number here means real particles were measured, not that the material looks suspicious.
How this specific polymer behaves — brittleness, fat solubility of its additives, thermal stability, whether it is a polymer named in existing restrictions.
What happened before you bought it. Retort sterilisation inside the pack, hot-filling, and pressurised brewing all happen at the most migration-favourable moment.
What we don't know
No particle measurement exists for aluminium capsules either. Lacquer composition is proprietary and manufacturers do not generally disclose it, so the internal coating is a genuine blank on this page — we can tell you it is thinner than a capsule wall, not what it is made of.

This page scores Nespresso Original aluminium capsule as a product. Formulations, packaging and suppliers change, and the specific item you own has its own condition — a scratched pan and a new one are not the same object. Scan yours for a score built from what is actually in front of you.

Each with the finding we use it for and the limitation that finding carries — because a study quoted without its boundaries is how this subject got so noisy.
- peer-reviewed2021
Ranjan 2021 — A disposable paper cup released roughly 25,000 micron-sized particles into 100 mL of hot water within 15 minutes — about the life of a takeaway coffee.
Limitation: Hot deionised water rather than coffee or tea, and a single cup type. It shows the polyethylene lining degrades at drinking temperature; it does not quantify a dose from a real latte.
- report2026
Earth Action 2026 — Estimated roughly 1,000 tonnes of microplastics migrate from packaging into food and drink annually — about 130 mg per person per year — with PET bottles responsible for around a third, and found UV exposure can raise release up to 100×.
Limitation: An industry-funded modelling exercise, not a laboratory study, and not peer-reviewed. We use it for the relative ranking of formats rather than for any absolute number.
