“We want it to be recyclable.”
This is one of the most frequently repeated phrases in cosmetic packaging—and at the same time, one of the most ambiguous if it is not properly defined. In practice, recyclable is not a simple yes/no question, nor does it depend solely on the material itself. It depends on how the entire packaging system is designed and whether it fits into a real, existing recycling stream.
When this is not properly addressed, the same issues arise again and again: packaging that “on paper” complies, but is lost in sorting facilities. Or design decisions that compromise the formula, the user experience, or a premium aesthetic.
In this article, we focus on what truly matters: what recyclable really means in cosmetics, where it often fails, the advantages of a method-driven approach, and which certifications and standards should be on your radar.
The benefits of designing for recyclability (when done properly)
When recyclability is treated as a design criterion—rather than a marketing adjective—it delivers very tangible benefits for brands:
- Fewer redesigns: avoiding last-minute changes because the overall system fails internal or market criteria.
- More defensible claims: reduced ambiguity, lower reputational risk, and easier alignment between marketing, purchasing, and legal teams.
- More efficient architectures: simplifying materials and components often reduces industrial complexity.
- Brand coherence: well-executed sustainability reinforces a perception of rigor, especially in premium segments.
Is recyclability about the material or the system?
Packaging is recyclable only if, under real conditions, it is collected, sorted, recycled, and the resulting material can re-enter the market as a viable raw material.
That is why two “PP” packages can end up with very different outcomes. One integrates seamlessly into the recycling stream; the other is excluded due to design details. In cosmetics, these issues are very common.
Where things usually go wrong: four typical issues
1. Multicomponent systems (pumps and dispensers)
A “monomaterial” jar or bottle paired with pumps, springs, seals, collars, or caps made of different—and sometimes inseparable—materials.
What happens: even if the body is recyclable, the full assembly may be difficult to sort or recycle with sufficient quality.
2. Premium decoration that masks or contaminates
Full metallisation, opaque lacquers, special inks, or coatings.
What happens: these can complicate material identification or reduce recycling quality. They are not prohibited, but they do require careful design choices.
3. Labels, adhesives, and sleeves
In many projects, the material selection is correct, but the issue lies in the label or adhesive.
What happens: if they do not detach or separate properly, they contaminate the recycling stream and are penalised by recyclers.
4. Formula compatibility
Fragrances, oils, active ingredients, alcohols, or sensitive formulas require barrier properties and material compatibility.
What happens: prioritising “recyclable” without validating compatibility introduces not only sustainability risks, but product risks.
Materials that tend to work best in cosmetics (a quick guide)
- PET: widely used for bottles; generally performs well, but becomes problematic with very dark or opaque colours, full sleeves, or incompatible labels and adhesives.
- PP: common for jars and caps; offers a good balance for cosmetic design, especially when a coherent component architecture is used.
- PE: relevant for rigid formats; challenges often arise in multilayer structures or when barriers are added.
- Glass: strongly associated with premium positioning and chemical inertness; challenges usually lie in closures, dispensers, decorations, and logistics impact.
- Aluminium: strong potential and excellent barrier properties; attention must be paid to internal coatings and component combinations.
The key takeaway is this: in cosmetics, the critical question is not “which material is recyclable?”, but rather “which combination of material, design, and components can be recycled in the target stream without compromising the formula or the brand?”.
Key certifications: what to request (and when)
There is no single, universal recyclability certification for cosmetic packaging. Best practice is to combine a framework for environmental claims with a technical design assessment.
- ISO 14021: guidance on how to formulate environmental claims (such as “recyclable”) in a verifiable and non-ambiguous way.
- EN 13430: framework to justify that packaging is recoverable through material recycling (useful for technical documentation).
- RecyClass / cyclos-HTP (and similar schemes): particularly valuable for complex packaging (multicomponent systems, premium decoration) or when the claim has high market visibility.
Practical rule: for simple, clearly mono-material packaging, a well-documented technical justification is often sufficient. For complex designs or critical claims, external assessment significantly reduces risk.
Mini-checklist: what a “recyclable” brief should include
To avoid unnecessary iterations, a proper brief should include at least:
- Target market (recycling systems vary by country)
- Target recycling stream (PET / PP / PE / glass / aluminium)
- Desired decoration level (and flexibility)
- Full packaging architecture (including dispensers, if any)
- Formula compatibility requirements
- Intended claim and required level of evidence
This allows projects to move faster, with fewer surprises.
In cosmetics, recyclability is not declared—it is designed. And it must be designed holistically: material, components, decoration, target stream, and formula compatibility.
When this approach is applied from the outset, the result is packaging that does not just “sound right”, but actually works—in the market, in industrialisation, and in brand coherence.
How Rafesa helps (without overcomplicating it):
At Rafesa, we believe the best starting point is a full system review—material, components, and decoration—to align design with the target recycling stream and the level of evidence required for the claim, without compromising the formula or the user experience.
