The EPR Escalation Most Manufacturers Still Haven’t Modelled

Red-rated polypropylene waste is not just a disposal problem. It is becoming a compounding financial exposure.

From April 2026, Red-rated plastic packaging under the UK EPR framework carries a materially higher fee than Green-rated material. 

For plastic, GOV.UK’s Year 2 illustrative fees show Red at £545 per tonne and Green at £415 per tonne. Add Plastic Packaging Tax at £228.82 per tonne from 1 April 2026, and manufacturers are already looking at more than £770 per tonne on material that may still be used once and permanently destroyed.

The uncomfortable truth is simple: this is not only a tax problem. It is a waste handling problem.

5 Key Takeaways

• Red-rated plastic material is already significantly more expensive than Green-rated material under the 2026/27 EPR framework.

• Plastic Packaging Tax rises to £228.82 per tonne from 1 April 2026 for qualifying plastic packaging with less than 30% recycled content.

• The Red EPR multiplier is not fixed. It rises from 1.2x in 2026/27 to 1.6x in 2027/28 and 2.0x in 2028/29.

• Polypropylene that is currently being incinerated may be technically recoverable if it is handled, processed, and verified properly.

• Every year of inaction is not a deferral. It is a compounding financial exposure.

The Hard Part Is Not Over

Most manufacturers looked at the April 2026 EPR changes and thought the hard part was over.

• It is not.

• It is just getting started.

The first wave of EPR costs forced businesses to look at packaging data, reporting requirements, producer obligations, and material classifications. That was uncomfortable enough.

But the larger issue is what happens next.

Because the Red multiplier is not designed to stay still.

It is designed to escalate.

That means a manufacturer that has not modelled its Red-rated waste stream through to 2028/29 is not looking at the full financial picture. It is only looking at the first year of a widening cost gap.

This is where the conversation needs to move from compliance to finance.

Not “have we reported the data?”

But “have we modelled what this material will cost us if we keep handling it the same way?”

The Numbers Are Already Moving

Right now, Red-rated polypropylene waste material that gets incinerated instead of recovered carries an EPR fee of approximately £545 per tonne under the published 2026/27 illustrative plastic rates.

Green-rated plastic sits at approximately £415 per tonne.

That is already a £130 per tonne difference.

Now, stack the Plastic Packaging Tax on top. HMRC confirms the rate rises to £228.82 per tonne from 1 April 2026 for qualifying plastic packaging that contains less than 30% recycled plastic.

That takes the combined exposure on Red-rated plastic material to more than £770 per tonne before the future Red multiplier increase is even considered.

That is the point most finance teams need to pause on.

Because this is not a one-year cost increase.

It is the beginning of a structural gap.

Sterimelt explores the wider cost issue in its blog on why hospital plastic waste can cost 40 times more to dispose of than normal rubbish.

The Red Multiplier Is the Part Many Teams Have Not Modelled

The Red multiplier is the part that changes the entire forecast.

• For 2026/27, Red-rated material is set at 1.2x the Amber fee.

• In 2027/28, that rises to 1.6x.

• By 2028/29, it reaches 2.0x.

Using the current illustrative Amber plastic fee of £455 per tonne as the baseline, that means Red-rated plastic moves from approximately £545 per tonne in 2026/27 to around £728 per tonne in 2027/28, and then to around £910 per tonne by 2028/29.

That is before the Plastic Packaging Tax is added.

This is why the cost of doing nothing is not flat.

It compounds.

A manufacturer that waits until 2028 to act will not be dealing with the same problem at the same price. It will be dealing with the same material under a much more expensive classification structure.

The Red-Rated Cost Escalation Finance Teams Need to See

Year	Red Multiplier	Approx. Red EPR Fee for Plastic	Plastic Packaging Tax Rate	Combined Exposure Before Other Costs
2026/27	1.2x	£545 per tonne	£228.82 per tonne	£773.82 per tonne
2027/28	1.6x	£728 per tonne	Subject to future rate	Higher again
2028/29	2.0x	£910 per tonne	Subject to future rate	Over £910 before PPT is added

These figures are based on current published EPR guidance and the 2026 Plastic Packaging Tax rate. Actual liability will depend on the material, packaging status, RAM rating, tonnage, recycled content, producer obligations, and final confirmed fees.

This Is Not Really a Tax Problem

The uncomfortable truth is that many manufacturers are treating this as a tax problem.

• It is not.

• It is a waste handling problem.

The same polypropylene material currently being incinerated may be technically recoverable. If it can be segregated, processed, stabilised, and moved into a verified recovery route, the issue changes completely.

The material does not have to remain a Red-rated disposal liability.

It can become a recoverable polymer resource.

That is the shift that matters.

The cost difference between Red and Green today is already £130 per tonne. By 2028/29, based on the Red multiplier trajectory, that gap could become far larger.

So the real question is not simply: “How much tax are we paying?”

The better question is: “Why is technically recoverable polypropylene still being destroyed?”

Sterimelt’s blog on why industrial polypropylene is treated as waste and how to monetise it goes deeper into this exact problem.

Polypropylene Has Value If the System Does Not Destroy It

Polypropylene is not low-value because of the material itself.

It becomes low-value when the system around it sends it to the wrong place.

Once polypropylene is mixed, contaminated, misclassified, or incinerated, its downstream value is gone. The business is left with cost, tax exposure, disposal fees, and no material recovery.

Sterimelt changes that outcome at the point of origin.

Instead of letting polypropylene enter a disposal route, Sterimelt applies controlled thermal processing to transform it into a sanitised, dense, stable block.

That block can be stored, transported, verified, and recovered.

The material does not disappear.

It is converted into something with genuine downstream value.

This matters because EPR is not only changing how businesses report material. It is changing the financial consequences of poor material handling.

Why 2028/29 Should Already Be in the Forecast

The mistake is looking only at this year’s fee.

Finance teams need to model 2028/29 now.

Not because the exact future bill can be known with total certainty, but because the direction of travel is already clear. Red-rated material becomes progressively more expensive. Green-rated recovery becomes increasingly valuable. The cost gap widens every year the business delays action.

That turns waste handling into a board-level issue.

If a manufacturer is producing repeatable polypropylene waste streams, the questions should be direct:

• How many tonnes are currently being destroyed?

• How much of that material is technically recoverable?

• What percentage is Red-rated today?

• What would the same tonnage cost in 2027/28?

• What would it cost in 2028/29?

• What operational change would move it from disposal to recovery?

Those are not sustainability questions.

They are financial risk questions.

The Reclassification Opportunity

The opportunity is not only to reduce waste volume.

It is to change the classification and destination of the material.

That is where Sterimelt becomes commercially relevant.

A business producing recoverable polypropylene does not need to accept incineration as the default endpoint. It can process the material at source, turn it into a stable block, and move it towards a verified recovery stream.

That can support a shift from Red-rated disposal exposure towards Green-rated recovery logic, depending on the material, process, and evidence trail.

This is the part that changes the conversation.

The machine does not just reduce cost.

It changes what the material becomes.

And when the material changes status, the financial model changes with it.

For a practical view of what recovered polypropylene can become after processing, see Sterimelt’s blog on what hospital blue wrap recycling can make possible.

Why Manufacturers Should Act Before the Multiplier Peaks

Waiting is expensive.

Every year a manufacturer delays action, the same waste stream moves further into a higher-cost environment.

• In 2026/27, Red-rated plastic is already more expensive than Green-rated plastic.

• In 2027/28, the Red multiplier rises again.

• By 2028/29, the Red fee reaches 2.0x the Amber fee.

That is not a warning sign. It is a timetable.

Manufacturers still have time to audit their polypropylene streams, separate recoverable material, trial point-of-origin processing, and build a verified recovery route before the highest multiplier arrives.

But that work cannot start after the finance team receives the 2028 bill.

It has to start while there is still time to change the waste handling system.

That is why this is not only a compliance issue.

It is an operational readiness issue.

Where Sterimelt Fits

Sterimelt is built for organisations producing repeatable streams of compatible polymer waste.

That includes manufacturers, healthcare suppliers, packaging users, industrial sites, and facilities dealing with polypropylene-based materials that are currently being treated as disposal liabilities.

The purpose is not to add another waste process.

The purpose is to stop valuable polymers from becoming waste in the first place.

Sterimelt’s point-of-origin technology converts compatible plastic waste into reusable material blocks, helping businesses reduce volume, improve recovery potential, and change the economics of disposal.

You can review the available machines and applications on the Sterimelt products and solutions page.

Wrapping Up!

The EPR escalation is not something manufacturers can afford to treat as background regulation.

It is a direct cost signal.

Red-rated polypropylene waste is already expensive. Plastic Packaging Tax adds another layer. 

The Red multiplier then pushes the exposure higher every year the same material keeps moving through the same disposal route.

The hard truth is this: The material may not be the problem.

The way it is handled is the problem.

If recoverable polypropylene is still being incinerated, the business is not only losing the material. It is accepting a compounding financial exposure that becomes harder to defend every year.

FAQs

1. What is EPR, and why does it matter for manufacturers?

Extended Producer Responsibility places more of the cost of packaging waste management onto producers. For manufacturers using or supplying plastic packaging, the material type, weight, recyclability, and classification can directly affect future costs.

2. What does Red-rated packaging mean?

Red-rated packaging is material assessed as less recyclable under the Recyclability Assessment Methodology. Under EPR modulation, Red-rated material attracts higher fees than Amber or Green material.

3. Why is polypropylene part of this conversation?

Polypropylene is widely used in packaging, healthcare, manufacturing, textiles, logistics, and industrial applications. Much of it is technically recoverable, but it often becomes costly waste because it is misclassified, mixed, contaminated, or sent to incineration.

4. How can Sterimelt help with Red-rated polypropylene waste?

Sterimelt can process compatible polypropylene waste at the point of origin, turning it into a sanitised, dense, stable block. This helps move material away from disposal and towards verified recovery routes.

5. Should finance teams model EPR costs beyond 2026/27?

Yes. The Red multiplier is scheduled to rise from 1.2x in 2026/27 to 1.6x in 2027/28 and 2.0x in 2028/29. Finance teams that only model the first year may underestimate the true cost of inaction.
