Introduction: The big misunderstanding in the packaging world
With the PPWR, “circular economy,” “recycling,” and “recyclate quotas” have finally become part of the packaging reality. At the same time, this has given rise to a misconception that I see time and again in projects: many companies treat recyclability and the use of recyclates as synonyms. At first glance, this seems logical—but technically, it is not. And it is precisely this confusion that becomes a risk under the PPWR, because both issues address different questions, occur at different points in the life cycle, and require different levers for implementation. If you separate them clearly, you can also merge them clearly—and that is exactly what this article is about.
What does “recyclability” mean? The property at the end of life
Recyclability describes whether packaging can actually be recycled in the real world after use—in other words, whether it can be collected, identified, correctly sorted, and then processed in the existing infrastructure to produce a usable secondary raw material. This is not a marketing statement, but a chain of technical conditions. In practice, recyclability is not a matter of “a little bit,” but rather a binary decision: if one link breaks, the rest doesn’t matter. A helpful rule of thumb is therefore: recyclability = design × sorting × recycling output quality.
Hurdle 1: Design for recycling – recyclability begins on the drawing board
Recyclability does not begin with the yellow bag, but rather with the design. This is where the course is set for whether the packaging will later fit into an established material stream. The material logic is crucial: a well-established plastic stream can only be used if the packaging is not thrown off track by incompatible materials or unnecessary material diversity. Colors and additives are just as important, because sorting technology works with optical and spectral signatures. Highly absorbent, very dark, or unfavorably pigmented surfaces can make packaging harder to recognize or cause it to slip into the wrong fraction. Finally, labels, sleeves, and adhesives are often underestimated factors: a sleeve that makes the body “invisible” or adhesives that do not come off cleanly during the washing process can impair the quality of the recyclate to such an extent that “something” is sorted, but no high-quality raw material is produced in the end.
Hurdle 2: Sorting – the packaging must be “readable” by machines
After collection, packaging waste does not undergo a perfect laboratory analysis, but rather passes through high-throughput systems. What matters there is whether the packaging can be quickly and reliably identified and assigned to the correct fraction. In practical terms, this means that your packaging must be designed in such a way that it can be correctly classified in milliseconds in terms of shape, surface, material combination, and design. If recognition fails or classification is unstable, the material does not end up where it belongs – and recyclability does not become “worse,” but practically ineffective because the material flow is lost.
Hurdle 3: Processing – ultimately, it’s the quality of the secondary raw material that counts
Even if packaging has been sorted, it is not automatically “recyclable in the sense of a cycle.” The decisive factor is whether it can be processed in the recycling process into a material that can be reused in defined applications. Washability, removability of printing inks and adhesives, tolerance to contaminants, and the stability of material properties all play a role here. The point is important: recyclability is not just “being recycled somewhere,” but “delivering a quality that enables substitution.” Without output quality, there is no stable demand—and without demand, there is no functioning cycle.
What is “recyclate use”? The composition at the beginning of life
Recyclate use means something completely different: it describes what the new packaging was made from—specifically, the proportion of recycled material in the product. This is an input issue and therefore a question of material procurement, specification, and processing. In practice, a distinction is usually made between post-consumer recycled material (from waste after use) and post-industrial recycled material (from production residues). For companies, it is crucial to note that the use of recycled material does not just mean “adding material,” but also encompasses processability, quality assurance, appearance, odor, mechanical properties, and supply chain stability. The use of recycled material is therefore a strategic decision at the beginning of the cycle – and initially says nothing about whether the packaging will be properly sorted and recycled to a high standard at the end of its life.
Note: Recyclate use describes the input. Recyclability describes the end-of-life potential.
One cycle, two stages: Where the terms really belong
When you consider the life cycle of packaging, the distinction becomes immediately clear. The use of recycled materials plays a role in production: what proportion of recycled material do you use, and how do you control specifications, batches, quality, and availability? Recyclability, on the other hand, only becomes apparent after use, when the packaging is collected, sorted, and processed. Mixing the two terms inevitably leads to miscommunication: one team talks about purchasing and processing recycled materials, while the other talks about design rules, sorting logic, and output quality. The two belong together—but not as synonyms, rather as two measuring points in the same chain.
The practical paradox: Two examples that end any discussion
In practice, two statements can be true at the same time – and that is precisely what makes the difference so important. Packaging can consist of 0% recycled material and still be highly recyclable if the choice of materials, design, and components are consistently geared toward established streams. Conversely, packaging can have a very high recycled content and still be practically unrecyclable if design decisions prevent recognition, create incorrect fractions, or contaminate the recycling process to such an extent that no usable output quality is achieved. This shows that the use of recycled material is an important signal for the circular economy – but it can never replace good design for recycling.
What does this mean under PPWR? Two obligations that you must manage separately
The PPWR draws a clear conclusion from this logic: it addresses both the recyclability of packaging and the use of recycled materials—as separate requirements. For companies, this means that it is not enough to simply design for recyclability and ignore recycled materials. Nor is it enough to use recycled materials if the design fails in terms of sorting or recycling quality. They must master both, but with different tools. Recyclability is achieved through design rules, sorting robustness, and output quality. The use of recycled materials is achieved through sourcing strategy, specifications, process windows, quality assurance, and verification logic. Those who accept this separation can make implementation plannable – instead of lumping both together and ending up with neither technical nor organizational stability.
The right strategy: First make recyclability robust, then ramp up recycled content steadily
Successful projects follow a clear technical sequence. First, the design is optimized for recyclability as much as possible: material and color concept, component logic (label/sleeve/closure), adhesive and additive strategy, separability, and recognizability. Then, the reality of sorting and recycling is consistently taken into account: Can the design be reliably recognized in practice? Will it remain in the right stream? Will the end result be of a quality that enables genuine substitution? Only when this chain is stable is the use of recycled material systematically scaled up – not as a symbolic gesture, but as a controlled process: with clear specifications, robust process windows, defined quality criteria, and a supply chain that reliably covers demand. This is exactly how you avoid the typical PPWR trap: increasing the proportion of recycled material while the end-of-life design later “loses” the material flow again.
Conclusion: Two key figures, one goal—and why the distinction is crucial for you
Recyclability describes the potential of packaging at the end of its life. Recyclate use describes the composition at the beginning. Both terms belong together—but only if you don’t confuse them. Under PPWR, you need dual expertise: You must design packaging so that it works in the real infrastructure, and at the same time you must integrate recycled content in a way that is technically and supply chain-wise manageable. Those who separate these aspects clearly and then systematically link them turn regulation into a real competitive opportunity: less risk, less friction in production and quality, better marketability, and a cycle that is not only claimed but is technically resilient.
If you wish, we can support you with a PPWR portfolio check: We analyze your formats in terms of design-for-recycling risks, prioritize quick wins, and derive clear design rules from this. At the same time, we develop a recycled material strategy that combines specifications, process windows, and quality assurance—so that recyclability and the use of recycled materials do not remain two parallel projects, but rather a functioning overall system.
