UK PRN shortage exposes gap between recycling targets and infrastructure

A sharp fall in recorded packaging recycling evidence has raised concerns over compliance costs and the capacity of the UK recycling system.

At the centre of the debate is a mechanism that may be unfamiliar to international packaging professionals: packaging waste recycling notes (PRNs). These certificates allow businesses subject to UK packaging recycling obligations to demonstrate that an equivalent amount of eligible packaging waste has been recycled.

The system depends on more than regulatory rules. Enough packaging waste must be collected, sorted and processed to generate valid evidence of recycling. If the supply of certificates tightens, compliance costs can rise even when the underlying reasons for the shortage remain unclear.

Recorded supplies of PRNs and their export equivalents fell by approximately 29% in the first half of 2026 compared with the same period a year earlier, according to data reported by recycling organisation RECOUP.

The decline has prompted questions about market reliability, compliance costs and whether legitimate operators can supply enough evidence to meet producers’ obligations.

However, fewer recorded certificates do not necessarily mean less packaging is being recycled or that the UK has lost physical recycling capacity. Reporting changes, tighter accreditation and action against fraudulent operators can also affect the supply of valid notes.

The underlying challenge is broader than the availability of compliance certificates. It is whether the UK’s regulatory framework, recycling infrastructure and commercial incentives are sufficiently aligned to deliver the volumes of material required by packaging policy.

What the recycling evidence figures show

Industry concerns intensified in July 2026, when RECOUP reported that Environment Agency data showed 417,365 tonnes of PRNs and packaging waste export recycling notes (PERNs) recorded between January and June, compared with 586,191 tonnes during the same period in 2025.

PERNs serve a similar purpose to PRNs but cover qualifying packaging waste exported for recycling overseas.

The decline of approximately 29% prompted discussions between the Department for Environment, Food and Rural Affairs (Defra) and industry representatives about its causes and the possibility of regulatory intervention.

However, RECOUP identified discrepancies between tabs in the underlying dataset and sought clarification from the Environment Agency. The figures therefore raised concerns about the supply of recycling evidence without establishing the scale of any nationwide shortage.

Subsequent government data releases distinguish between notes already issued and material recorded in operators’ waste balances. These balances include material against which notes have already been issued, as well as material that could support future issuance.

The dataset was updated on 25 September using information extracted on 21 September. Late submissions and revisions can change the totals.

Assessing a genuine shortage requires more than comparing headline figures. Available evidence must be examined by material and measured against producers’ obligations, taking account of reporting gaps and material that could support further note issuance.

This distinction matters because a shortage of recorded evidence, a shortage of valid notes available for purchase and a shortage of physical recycling capacity are related but different problems. Each requires a different response.

How the UK PRN system works

PRNs are part of the UK’s extended producer responsibility framework for packaging. The principle is that businesses placing packaging on the market must help ensure that the resulting waste is recycled, with their obligations linked to the packaging they handle.

Rather than requiring each business to recycle its own packaging, the system uses certificates to connect producers’ obligations with recycling activity elsewhere in the supply chain.

Accredited UK reprocessors issue PRNs against eligible packaging waste recycled domestically. Accredited exporters issue PERNs for qualifying packaging waste sent overseas for recycling.

Businesses subject to recycling obligations obtain these notes directly or through producer compliance schemes, which manage compliance on their behalf. Each note represents eligible recycling tonnage, not necessarily the recycling of the producer’s own packaging.

The notes are traded, creating a market in which their prices reflect factors including the availability of eligible recycling evidence and demand from businesses seeking to meet their obligations.

The system also generates revenue intended to support recycling operations and investment. In a parliamentary answer published in June 2026, the government said PRN and PERN sales generated £322m in 2025. Accredited operators must report how they use that revenue to help increase recycling capacity.

For producers, restricted evidence supply can increase purchasing costs and make compliance budgets harder to predict. In September, Packaging Gateway reported, citing British Retail Consortium analysis, that average plastic PRN prices had risen from around £180 per tonne in 2025 to more than £370 per tonne in 2026.

These figures relate specifically to plastic PRNs, rather than the entire packaging market.

Higher prices can increase the potential revenue available to eligible operators, but they do not automatically translate into new recycling capacity. Investment depends on more than the price of compliance evidence: operators also need reliable supplies of suitable waste, commercially viable processing costs and customers for the recycled materials they produce.

This is where the relationship between regulation and infrastructure becomes critical. Recycling targets create obligations, while PRNs and PERNs create a market for evidence that eligible recycling has taken place.

Neither guarantees that enough suitable material will be collected or that facilities will have the capacity and commercial incentive to process it.

How stronger enforcement affects supply

One issue under examination is whether tighter controls have removed invalid evidence from the market.

RECOUP’s July update said Defra was seeking industry views on the effects of new accreditation and reporting requirements, alongside increased enforcement. Officials also wanted to understand whether legitimate operators could increase output and secure suitable material at the right price and quality.

The Environment Agency’s 2025 enforcement report illustrates the integrity challenge. The agency reported disrupting suspected fraudulent PRN claims associated with 279,429 tonnes of packaging, with an estimated note value of £32.8m.

These figures relate to suspected fraudulent claims targeted by enforcement activity. They do not represent an equivalent loss of legitimate recycling capacity, nor do they establish how much of the subsequent decline in recorded evidence resulted from enforcement.

Removing invalid claims is essential to maintaining confidence in the system and ensuring that compliant businesses are not disadvantaged by fraudulent competition. However, stronger enforcement can also expose how much legitimate evidence is available once invalid claims are excluded.

Regulators therefore need reliable data to distinguish between an apparent shortage caused by improved oversight and a genuine shortfall in the market’s ability to supply valid notes. Without that distinction, policy responses risk addressing the wrong problem.

What the proposed reforms would change

Defra’s March 2026 consultation on PRN reform proposed a mechanism for exceptional circumstances in which an unavoidable shortage of PRNs or PERNs would make compliance with recycling targets impossible.

Other proposals included more consistent measurement of recyclable material, cancellation of illegitimately issued notes and greater transparency around operator accreditation. The consultation also addressed registration and reporting requirements for trading platforms and brokers.

The proposed changes aim to reduce fraud and error while improving competitive conditions between domestic reprocessors and exporters.

The consultation closed on 5 May and received 81 responses. The government’s published update said a joint response from the four UK governments was due in autumn 2026.

The proposed shortage mechanism should not be treated as an established compliance option until the government confirms its decision and any implementation arrangements.

For policymakers, the challenge is to identify when the supply of legitimate evidence is genuinely insufficient, rather than temporarily affected by reporting delays or changes in enforcement.

Any contingency mechanism must give producers a workable route through exceptional shortages without weakening the incentive to collect and recycle packaging waste.

Crucially, easing compliance during a shortage would not, on its own, resolve the underlying infrastructure constraints. It could address an immediate regulatory problem while leaving the collection, sorting and processing capacity needed to meet future targets unchanged.

Why recycling infrastructure remains the missing link

Reforming the evidence market can improve transparency and reliability, but it cannot by itself deliver additional recycling output. That requires a functioning physical system capable of handling packaging waste generated by households and businesses.

A reprocessing plant needs suitable incoming material, effective sorting and processing equipment, and customers for its recycled output. Its stated capacity does not necessarily reflect how much packaging it can process economically or how quickly production can increase.

Constraints also differ by material. Plastics recycling depends on factors including polymer type, contamination and incoming material quality. Paper, glass and metals have different processing requirements and market conditions.

The type of constraint matters when deciding where investment is needed. A facility operating at full capacity but unable to expand may need new equipment or a larger site.

An underused plant may instead be struggling to secure suitable feedstock, while another may lack buyers willing to pay enough for its recycled output.

These are not interchangeable problems. Increasing processing capacity will have limited effect if collection systems fail to supply suitable material. Improving collection will not necessarily make recycling commercially viable if processing costs are too high or demand for recycled output is weak.

The distinction also matters when comparing domestic reprocessing with exports. Exporters can provide access to additional recycling capacity, but regulators must ensure that exported waste is genuinely recycled and that evidence is measured consistently.

Domestic investment, meanwhile, depends on the prospect of a dependable supply of material and a viable market for the resulting recyclate — the recovered material used to manufacture new products.

The infrastructure mismatch is therefore not simply a question of building more plants. It concerns the alignment of collection, sorting, reprocessing, end markets and regulatory incentives across the entire recycling chain.

For packaging businesses, this strengthens the case for designing products around practical end-of-life routes. Material selection, component separation and contamination can influence whether packaging can be collected, sorted and processed effectively.

Better design cannot replace missing infrastructure, but it can help available facilities make better use of their capacity.

What packaging businesses should watch next

The government’s response to the PRN reform consultation is an important policy milestone. Producers, compliance schemes and recycling operators will need to examine which measures are adopted, when they take effect and whether they change evidence purchasing, accreditation or reporting arrangements.

In the meantime, businesses should review compliance exposure by material, monitor PRN and PERN availability and work with compliance partners to plan purchases early. They should also check that evidence is obtained through legitimate, appropriately accredited operators.

International packaging manufacturers and brand owners supplying the UK should understand how PRNs and PERNs fit into the country’s wider packaging compliance framework. Evidence costs are one part of that exposure; packaging design, waste management arrangements and applicable producer responsibility fees must also be considered.

The longer-term test for reform is whether it can preserve credible recycling evidence while giving producers a dependable route to compliance and legitimate operators a stronger basis for investment.

Meeting packaging recycling targets requires more than setting obligations or issuing certificates. It requires enough suitable waste to be collected, enough infrastructure to process it and enough demand for recycled materials to keep the system commercially viable.

Unless those elements develop alongside regulation, the gap between policy ambition and practical recycling capacity will remain a challenge for the UK packaging industry.
