Europe’s packaging industry is being told to use more recycled plastic.
That sounds straightforward until a converter has to buy it.
Two suppliers may both offer recycled HDPE.
Both may provide technical data sheets.
Both may describe their material as high quality.
Both may claim suitability for demanding extrusion applications.
But are the two materials actually comparable?
Do they come from similar waste streams?
Do they have similar processing histories?
Will melt behaviour remain stable from batch to batch?
Can a blow-moulding operation switch from virgin HDPE without creating more scrap, instability or quality risk?
And, increasingly important, can the purchaser document what it bought if a customer or regulator asks?
Those questions sit behind a new certification awarded to Schütz for the recycled material used in its Green Layer industrial packaging.
The regranulate achieved 9.3 out of 10 under plastship’s newly developed Monitored Materials system, earning its highest “Premium” classification.
According to plastship, the material ranks among the top 5% of the 224 materials in its current database and has application and processing properties comparable with virgin material.
The score makes a good headline.
But the more important development may be the attempt to turn recyclate quality from something described differently by every supplier into something buyers can compare systematically.
As recycled-content requirements rise, the packaging industry’s next shortage may not simply be recycled polymer. It may be recycled polymer with enough reliable data to qualify confidently.
The Problem Is Bigger Than One Schütz Regranulate
Virgin polymer has traditionally given plastics processors a relatively predictable starting point.
A converter specifying a particular virgin HDPE grade can evaluate established properties, processing windows and supplier specifications.
Recycled polymer is different.
Its properties can be influenced by:
- the original products entering the waste stream,
- polymer mixing,
- contamination,
- degradation during previous processing,
- additives,
- colour,
- washing and sorting efficiency,
- repeated thermal histories,
- and the recycling process itself.
That does not mean recyclate is necessarily inferior.
Schütz’s result is intended to demonstrate exactly the opposite.
It does mean that the word “recycled HDPE” alone does not describe enough about the material for an industrial processor to make a confident substitution decision.
That is the gap plastship says its Monitored Materials system is trying to address.
Instead of relying on differently structured individual technical data sheets, the platform standardises material information and combines laboratory testing with information on material flows.
Materials receive a score between zero and 10 and are grouped into Premium, Plus or Proven classifications.
For procurement teams, the underlying idea is potentially more important than the ranking itself:
make recycled resin easier to compare before spending weeks qualifying it.
Schütz Is a Useful Test Because the Application Is Demanding
Schütz does not use the assessed material merely for a low-risk plastic accessory.
Its Green Layer portfolio incorporates recycled HDPE into extrusion blow-moulded IBC inner bottles and plastic drums.
In the company’s three-layer design, recycled material forms the middle layer, accounting for 30% of the inner bottle or drum body.
Virgin material remains on the inner and outer surfaces.
As a result, the filling product and the external environment come into direct contact only with virgin polymer.
For an IBC inner bottle, Schütz says this can represent up to 4.35 kg of recyclate.
For a 220-litre Green Layer drum, the recycled content in the plastic body is 30%, corresponding to 2.43 kg.
Several Green Layer configurations also carry UN dangerous-goods approvals.
That makes material consistency important.
An industrial packaging producer cannot increase recycled content simply by putting whatever post-consumer HDPE is available into an extrusion hopper.
The polymer has to run through the process predictably and the finished packaging still has to meet the required product specifications.
This is why the 9.3 score is commercially interesting.
The important claim is not that the material is recycled.
It is that plastship’s assessment found its processing and application properties comparable with virgin material.
That is a considerably higher bar.
But “Comparable With Virgin” Needs Careful Wording
There is also a reporting limit here.
The material received the 9.3 score under plastship’s own Monitored Materials assessment system.
Plastship states that the database now contains 224 materials and describes the Schütz material as ranking in the top 5% of the European market.
Those are plastship’s assessment results.
The information publicly available does not provide enough detail for us to independently reproduce the 9.3 calculation or verify that the 224-material database represents the entire European recyclate market statistically.
So I would not report:
“Schütz has independently proven that its recycled HDPE is one of Europe’s best recyclates.”
That goes further than the evidence.
The defensible statement is:
Under plastship’s Monitored Materials methodology, the Schütz regranulate scored 9.3, received Premium classification and was assessed as comparable with virgin resin in relevant use and processing properties.
That difference matters in professional packaging coverage.
The Real Procurement Problem Starts Before the Extruder
The usual discussion around recycled content focuses on manufacturing.
Can the resin be extruded?
Can the package pass testing?
Can the percentage of virgin polymer be reduced?
But qualification starts earlier.
A packaging converter first has to find material worth testing.
That search itself can be inefficient.
Consider a procurement team examining five possible recyclates.
Each supplier may provide different data.
One TDS may include melt flow rate but not density variation.
Another may provide mechanical values tested to different standards.
Another may disclose feedstock origin.
Another may not.
A fifth may provide only typical values rather than batch-related information.
The procurement team then has to decide which material deserves:
laboratory evaluation,
pilot production,
machine trials,
packaging testing,
customer approval,
and ultimately a supply agreement.
That process costs money before a single commercial package is sold.
Plastship argues that standardized datasets can reduce this initial search and qualification effort by making material properties more directly comparable. Its system also allows subscribers to compare materials against virgin references and other recyclates and includes production-capacity information intended to support sourcing decisions.
If that approach works at scale, the commercial benefit may be significant.
The faster converters can eliminate unsuitable materials before plant trials, the cheaper recycled-content qualification becomes.
Availability Is Not the Same as Usable Availability
This becomes especially important as PPWR creates additional demand for recycled plastic.
Under the final EU Packaging and Packaging Waste Regulation, plastic packaging subject to the general category will eventually need minimum recycled content recovered from post-consumer plastic waste.
The regulation sets a 35% requirement for many plastic packaging formats, with different percentages for specified contact-sensitive applications and beverage bottles. The calculation is based on averages per manufacturing plant, year, packaging type and format, subject to the regulation’s detailed timetable and exemptions.
By 2040, the general requirement rises to 65%.
That will increase demand for qualifying PCR.
But tonnes alone do not solve the problem.
Suppose the market technically has sufficient recycled HDPE available.
If half of those tonnes cannot meet a converter’s processing requirements, then the converter does not really have access to that full supply.
The distinction is:
available recyclate
versus
qualified recyclate.
For high-performance packaging, qualified supply is what matters.
That is why systems that connect physical resin availability with material-quality data could become strategically important.
The 30% Green Layer Figure Should Not Be Compared Directly With 35%
There is an obvious temptation here.
Schütz Green Layer:
30% recyclate in the three-layer inner bottle or drum body.
PPWR general recycled-content requirement:
35% for certain plastic packaging from the applicable 2030 timetable.
It would be easy to write that Green Layer needs another five percentage points to comply.
That would be wrong.
PPWR calculations depend on the specific packaging classification, format, manufacturing averages, origin of recycled feedstock and applicable exemptions.
There is an especially important qualification for Schütz.
PPWR Article 7 exempts packaging used for the transport of dangerous goods from the mandatory recycled-content percentages.
Schütz offers Green Layer IBCs and drums with UN dangerous-goods certification.
That does not mean every Green Layer package is exempt.
The exemption depends on its use.
But it does mean that a simple comparison of 30% versus 35% would misrepresent the regulation.
This is precisely why packaging compliance is becoming a data problem as well as a material problem.
The industry needs to know not merely:
how much recyclate is in the package?
but also:
what material is it, where did it come from, what packaging format is it used in, how is the percentage calculated, and which regulatory provision applies?
EN 18065 Is Another Detail That Should Not Be Oversold
Plastship says Monitored Materials is aligned with EN 18065.
The standard is real.
EN 18065:2025 covers the classification of recycled plastics based on data-quality levels for use and digital trading. The German DIN version was published in November 2025.
But this distinction is important:
EN 18065 is about the quality and classification of recyclate data.
It should not be interpreted as a universal standard declaring that a particular recycled polymer performs identically to virgin material.
Nor does plastship’s statement that its system is “aligned with EN 18065” automatically mean the Monitored Materials certificate itself is an official EU regulatory approval.
Those are separate questions.
So the certificate may help create structured evidence for future procurement and compliance work.
It should not be described as “PPWR certification.”
PPWR itself will rely on implementing and delegated rules governing recycled-content calculation, verification, technical documentation and recyclability assessment.
The details matter.
PPWR Is Quietly Changing What Counts as a Valuable Recyclate
For years, recycled plastics markets have often been discussed mainly through price.
Virgin HDPE costs X.
Recycled HDPE costs Y.
The buyer chooses according to economics and specification.
PPWR adds another dimension:
regulatory value.
A recycled material may become more valuable if its origin, quality and recycled-content status can be demonstrated reliably.
That creates the possibility of increasingly differentiated recyclate markets.
At one end:
material with uncertain origin, variable quality and limited supporting data.
At the other:
well-characterized material from a controlled stream, with consistent processing properties, traceable flows and standardized documentation.
Both may technically be recycled polyethylene.
They may not be commercially equivalent.
That could change procurement significantly.
Packaging producers may become willing to pay not simply for the polymer itself, but for confidence in the polymer.
Schütz Has an Advantage That Many Packaging Producers Do Not
Schütz’s system also reveals another structural advantage.
The company operates a closed material loop around its industrial packaging.
Used IBCs and drums can be collected through its recovery system.
Reusable components are reconditioned.
Plastic inner bottles and drums that leave the reuse cycle can be recycled.
Schütz then processes recovered HDPE in its own recycling centres and uses part of that material in new packaging components, including Green Layer products.
That gives Schütz more control over its feedstock than a converter buying anonymous recycled resin on the merchant market.
The company says it controls incoming material and uses processes including sorting, degassing, colour grading and regranulation before the material returns to production.
That control matters.
Recyclate consistency begins with the waste stream.
If the producer knows:
what packaging entered the collection system,
what polymer it contained,
what it previously carried,
how it was sorted,
and how it was reprocessed,
it has a better basis for controlling the secondary raw material.
For converters without their own collection network, that information has to come from suppliers.
Which brings us back to the need for standardized data.
Certificates Will Not Eliminate Production Trials
There is a limit to what a material database can solve.
A 9.3 score does not mean another converter can purchase the same material, feed it into any machine and immediately replace virgin resin.
Processing behaviour depends on:
machine design,
temperature profile,
screw geometry,
mould configuration,
wall thickness,
masterbatch,
product geometry,
cycle time,
and required finished-package performance.
Customer specifications may introduce additional constraints.
For demanding packaging applications, laboratory data should therefore reduce qualification risk—not replace application qualification.
That distinction will remain important.
A standardized material dataset can tell an engineer:
“This resin looks worth testing.”
It cannot always tell the engineer:
“You no longer need to test it.”
That is still valuable.
Removing the wrong candidates earlier can save substantial plant time.
The Industry Is Moving From Recycling Claims to Material Evidence
This may be the most important change behind the Schütz certificate.
For years, the plastics industry could communicate circularity through relatively simple numbers:
30% recycled.
50% recycled.
100% recyclable.
But regulation and industrial procurement are making those claims harder.
The next questions are becoming:
30% of what?
Calculated how?
Post-consumer or pre-consumer?
From which stream?
Verified by whom?
Measured at what production level?
With which mechanical properties?
How stable is supply?
What happens after another recycling cycle?
Can the material substitute virgin polymer in the same application?
Those are much more technical questions.
They are also much more useful.
One Score Will Not Standardize Europe’s Recyclate Market
It is too early to declare Monitored Materials a new European benchmark.
The database currently contains 224 materials, according to plastship.
That is enough to begin comparisons.
It is not enough to assume that every polymer type, waste stream, country, recycling technology and application is comprehensively represented.
The system also operates commercially, with some database functions accessible to customers and annual subscribers.
Adoption will therefore matter.
Will recyclers submit enough material?
Will converters trust the methodology?
Will major brand owners recognize the classifications?
Will other testing systems produce competing data structures?
And, eventually, will regulators or harmonized standards make some of these private comparison tools unnecessary—or more valuable because they provide the underlying evidence?
Those questions remain open.
The first Schütz certificate establishes a starting point, not the final market standard.
The Real Bottleneck May Become Confidence
Europe is preparing to force more recycled plastic back into packaging.
That can create demand.
It cannot automatically create high-quality supply.
Recyclers still have to produce consistent material.
Converters still have to qualify it.
Packaging producers still have to protect the contents.
Procurement teams still have to manage price and availability.
And companies will increasingly need documentation capable of surviving customer and regulatory scrutiny.
That is why Schütz’s 9.3 rating matters less as a trophy and more as a sign of what the recycled-plastics market is becoming.
Recyclate will increasingly be bought not only by polymer type and price, but by quality evidence, traceability and confidence that it can perform repeatedly in an industrial process.
The transition from virgin resin to recycled resin therefore has two infrastructure requirements.
Europe needs recycling plants capable of producing the material.
But it also needs data infrastructure capable of telling processors which material they can actually use.
PPWR may accelerate the first requirement.
Systems such as Monitored Materials are betting that the second will become just as important.
For packaging converters and procurement teams, that raises the question worth discussing now:
When PPWR increases your recycled-content requirement, will your bigger problem be finding enough recyclate—or proving that the recyclate you found is good enough to put into production?
