What the rPET spread is actually telling you

A widening recycled-PET spread looks like the demand pull the EU's new mandate promised. Through 2025, with the premium near EUR 600 a tonne (ICIS, Q1 2025) and brands cutting recycled content to the legal minimum, it told the opposite story — a feedstock-quality warning.

Read that headline gap as a thermometer, not a thesis. The consensus is sound as far as it goes: demand is now in law, supply is short, so the premium of recycled PET (rPET) over virgin resin should keep widening and recyclers should be a structural long. The Packaging and Packaging Waste Regulation (PPWR, Regulation (EU) 2025/40) entered into force on 11 February 2025 and applies from 12 August 2026, and its Article 7 sets minimum recycled content of 30% by 1 January 2030 for contact-sensitive PET packaging and for single-use plastic beverage bottles, counting post-consumer recyclate only.¹² The demand is real and dated. The reading of the spread is where the consensus goes wrong: the market reads one number where there are three.

"The rPET spread" is not the headline gap of recycled over virgin. The spread that prices the mandate sits one layer down, inside rPET itself, between feedstock that can clear food-contact specification and everything that cannot. When the headline gap blows out while brands cut recycled content to the minimum, the spread is not flagging demand to chase. It is flagging that the marginal recycled molecule is too dirty or too costly to qualify. That is a feedstock-quality warning, and it is the signal worth tracking.

Two spreads and a behaviour, not one line

The common read tracks a single line, the premium of rPET over virgin, and takes a wider gap as bullish for recyclers. A blow-out there can mean strong demand, or it can mean the marginal recycled tonne cannot clear specification at an acceptable cost. The two look identical on one chart, which is why the chart misleads.

Decompose the gap and ask which part is moving:

Read the three together. A wide headline spread, a wide quality spread, and brands flexing to the legal minimum is a feedstock-quality crunch: bullish for the spec-compliant tonne, bearish for undifferentiated flake. A wide headline spread alongside a narrowing quality spread, with content held above the minimum, would be the genuine one-way demand pull the consensus assumes. That second pattern is the falsifier, and it is not what the 2025 data showed.

What the quality spread looks like in practice

The premium for clean, traceable feedstock is directionally clear in vendor data, and one proxy puts a number on it. High-purity bottle bales from deposit-return schemes (DRS) clear food-contact specification far more reliably than kerbside material. TOMRA, citing US data, valued California DRS-collected PET bales at roughly 88% above kerbside-collected PET as of April 2025, with a general norm nearer 40%.³ Treat that as the best available proxy for the food-contact quality spread, not the spread itself.³ The direction is the point. Under post-consumer-only counting, the high-purity tonne reliably qualifies and earns the mandate's premium; the rest does not.

The headline spread, meanwhile, has behaved in a way the consensus story struggles to explain. ICIS assessed the rPET-over-virgin gap in Europe at around EUR 600 a tonne in the first quarter of 2025, with food-grade rPET pellets up to roughly EUR 1,800 a tonne, an approximately 80% premium.⁴ What matters is the response it provoked.

The demand is real and dated. The reading of the spread is where the consensus goes wrong: the market reads one number where there are three.

What brands did when the spread widened

Faced with that gap, brands cut recycled content toward the legal minimum rather than pay up. ICIS reported European brands trimming rPET to minimum contracted volumes, typically 25 to 30% for beverage bottles, citing weak enforcement and Coca-Cola's December 2024 reduction of its sustainability commitments as emboldening companies to meet only the regulatory floor.⁴ That is minimum-compliance gaming, and it is what the quality read predicts: a legislated demand floor that produces floor-hugging behaviour is not the structural long the headline implies.

Supply tells the same story from the other side. In the United States, five full or partial rPET plant closures were reported since early 2025; the US PET bottle collection rate fell to 30.2% in 2024 from 32.5% in 2023; bottle post-consumer content ran just under 16%; and imports supplied roughly 25% of US rPET nationally, approaching 50% in some regions.⁵ A legislated demand story has not protected domestic supply. Collection and sorting quality, not headline demand, is the binding constraint, and that is where the spread is pointing.

A spec mandate that priced the compliant grade before

There is a clean precedent for a rule that pays for a specification rather than a tonne. IMO 2020, the global 0.50% sulfur cap on marine fuel (down from 3.50%), took effect on 1 January 2020 and split a single fuel market into a compliant grade (VLSFO) and a non-compliant one (HSFO).⁶ On bunker-market assessments the compliant-grade premium spiked during the early-2020 compliance scramble, into the low hundreds of dollars a tonne on a range basis, then narrowed toward USD 60 and below as compliant supply caught up.⁶ The mechanism transfers, and the difference decides the call.

A spec mandate prices the compliant grade, not the tonne, and that premium can be transitional, spiking at enforcement and compressing as supply scales. The hinge is how fast the compliant grade can be made. VLSFO scaled quickly: compliant fuel could be blended to spec from existing streams within roughly a year, alongside new low-sulfur runs and scrubber fitting.⁶ Food-contact rPET has no such shortcut: it is gated by collection economics and food-contact authorisation, which scale over years. The quality spread should therefore prove stickier than IMO 2020's, which is the heart of the steelman below.

The decisive number is the one no one publishes yet: how much of a real plant's output clears to certified, food-contact specification.

Base, better, and worse

The base case carries the most weight, because EU recycling rates remain well below target and food-contact authorisation lead times are long, so spec-compliant supply cannot scale into the mandate quickly. In it, the intra-rPET quality bifurcation persists and deepens into the August 2026 application date and the 2030 targets. Food-contact, chain-of-custody feedstock holds a durable premium while ordinary flake prices as the residual. Eurostat reported the EU recycled 42.1% of plastic packaging waste in 2023, up from 38.2% in 2013; the bloc's 2030 plastic-packaging recycling target is 55%, set in EU packaging-waste law, not in that Eurostat release.⁷⁸ The distance between the two is the size of the feedstock-quality problem.

In the better case, enforcement tightens and the regulatory perimeter widens. California's SB 54 permanent regulations took effect on 1 May 2026, with a producer-registration deadline of 1 June 2026 and targets of a 65% plastic recycling rate by 2032.⁹ As audits harden and more deposit-return schemes scale high-purity collection, floor-hugging stops paying and the quality spread widens further.

The worse case is the falsifier itself: the legislated floor lifts all recycled flake roughly equally, and the bifurcation never arrives. A separate downside, not to be confused with the falsifier, is a sustained virgin-resin slump that widens the recycled discount enough to stall investment in spec-compliant collection, deferring the re-rating rather than disproving it. Both are watched, not assumed.

What to watch

The signposts are concrete, and each both confirms and falsifies the read. They subsume the diligence a position would run: the first row asks what share of any exposure's output is food-contact, post-consumer, and chain-of-custody-certified, since that countable share, not the nameplate tonnage, is what the mandate pays for.

Track virgin-resin levels for direction and context, not as a curve the rPET spread is modelled off, because rPET does not move one-for-one with the virgin or naphtha curve.

The strongest case against this, and our answer

The strongest version of the consensus, which is also the falsifier, is that the quality bifurcation is transitional and compliant supply scales fast. Concede the point underneath it: the PPWR targets are post-consumer-only, so they do not lift ordinary flake directly. The sharper bear case is that spec-compliant capacity is being built precisely where the premium sits and could compress the quality spread within a couple of years. India is the live evidence. Trade-press reporting on FSSAI and MoEFCC rules describes a 40% recycled-content mandate for food-grade PET packaging from 1 April 2026 and a build-out of food-grade capacity which, if it generalises, points toward parity.¹⁰ IMO 2020 arms this case directly: there, the compliant-grade premium did compress as supply scaled, in roughly twelve months.

Our answer rests on the one distinction the analogue exposes. The compliant grade in rPET cannot be blended into existence the way marine fuel was; it is gated by collection economics and food-contact authorisation, the slow constraints set out above, and EU recycling rates sit well short of target. So the compliant supply that would close the quality spread arrives over years, not the twelve months IMO 2020 took. The India build-out is the test of exactly this. The cited near-cost-parity claim there is unverified and not treated as fact; but if it verifies, it materially strengthens the bear case, and that is the single development that would most change this view.¹⁰ The honest concession stands: the headline spread is partly a real demand signal, so a framework that dismissed it outright would miss genuine tightening.

Hold this as a feedstock-quality read sized to the spec-compliant slice, not a sector-long on recyclers. It holds as long as the quality spread stays wide and floor-hugging keeps paying. Cut it, do not defend it, if three conditions co-occur and persist: the headline spread compresses durably toward parity, brands hold content above the legal minimum, and the DRS-over-kerbside premium collapses. Those three together are the falsifier firing, the bifurcation that never arrived.

This is the read from inside the recycled-materials chain rather than from the index. We develop the broader sector view in the 2026 circular-materials outlook and the feedstock competition behind it in the UCO supply note. The decisive number is the one no one publishes yet: how much of a real plant's output clears to certified, food-contact specification. Until that number exists, the spread one layer down is the best instrument available for reading the tightness the mandate is creating.
