EU Moves to Allow Mass-Balance for Chemical Recycling in Bottles: A Controversial Step Forward
The European Union is weighing new rules that would permit the use of mass-balance accounting to calculate recycled content from chemical recycling in single-use plastic bottles. This shift, proposed under the Single-Use Plastics Directive (SUPD), could redefine how chemically recycled plastics are measured, tracked, and marketed — but it is already stirring heated debate.
What Is the Mass-Balance Proposal?
Under the draft implementing act, the EU would allow chemical recycling facilities to use a “fuel-use-exempt” mass-balance model. That means only the portion of output that does not go into fuel production could be counted toward recycled plastic content. bkv-gmbh.de+2europen-packaging.eu+2
In addition, a conversion factor could be introduced for “dual-use” outputs — such as pyrolysis oils, which can be processed either into virgin-grade plastics or into fuels. bkv-gmbh.de The idea behind the model is to bridge chemically recycled inputs and conventional plastic production, allowing recycled feedstock to be blended in large-scale industrial streams without needing physical separation.
Why It Matters for Packaging Recycling
This proposal connects directly to the EU’s broader strategy: new rules under the Packaging and Packaging Waste Regulation (PPWR) set ambitious targets for recycled content in plastic packaging. Consilium+2Consilium+2
By permitting mass-balance for chemical recycling, the EU aims to drive investment in advanced recycling technologies — particularly for plastic waste that mechanical recycling cannot handle. EU mass balance chemical recycling bottles
According to stakeholders, these rules could unlock major chemical recycling projects by offering a way to credit recycled content in high-value applications. europen-packaging.eu+1
Support From Industry — And Concerns From Critics
Industry groups are largely backing the proposal. Many see the mass-balance method, especially the “fuel-use-exempt” variant, as crucial to scaling chemical recycling. EU mass balance chemical recycling bottles
eumeps.eu A cross-sectoral industry statement argues that mass-balance allows integration of recycled feedstocks into existing production without the huge cost and complexity of building fully separated recycling facilities. europen-packaging.eu
However, environmental groups are deeply skeptical. Organizations like Zero Waste Europe warn that a flexible mass-balance system could enable greenwashing — companies might claim high recycled content without physically incorporating that material into final products.

What the Rules Say — and What’s Next
Under the EU’s current Implementing Decision (2023/2683), chemically recycled plastic that is indistinguishable from virgin material lacks transparency in recycled-content claims. EU mass balance chemical recycling bottles
EUR-Lex The proposed new draft act would supersede this by establishing a chain-of-custody system rooted in ISO 22095-2020, with third-party certification and verification. EU mass balance chemical recycling bottles
Notably, the draft act explicitly states that mechanical recycling remains the environmental priority. Processes that can achieve high-quality recyclate via mechanical means should be used first, reserving chemical recycling for more complex or contaminated streams. The Acta Group
Transparency and Traceability Challenges
One of the biggest issues is traceability. EU mass balance chemical recycling bottles
The mass-balance method runs the risk of recycled credits being allocated without a clear, physical connection to the final product. Critics call for strict definitions, real-world data, and independent audits to prevent misuse. fead.be FEAD, a major European waste management association, argues that any mass-balance model must include robust definitions, rules about losses and by-products, and tight traceability. fead.be
Meanwhile, Zero Waste Europe demands a more constrained allocation method — for instance, allocation at the batch level using proportional sharing — to curb the risk of overstated recycling performance. Zero Waste Europe
Implications for the Circular Plastics Economy
If adopted, the EU’s mass-balance proposal could unlock large-scale chemical recycling investments. By allowing chemically recycled plastic to count toward recycled content targets, companies might be more likely to build or expand recycling plants — helping accelerate the transition to a circular economy. europen-packaging.eu+1
On the other hand, weak rules or poor enforcement could undermine public trust. Without clear accountability, there is a risk that firms might game the system — claiming recycled content without sufficient environmental benefit.
What’s Next
The European Commission opened a public consultation in mid-2025, inviting stakeholders to comment on the draft act. The Acta Group This process will be closely watched by both industry and civil society as it could set a regulatory precedent not only under the SUPD but also in future regulations like the PPWR.

Lawmakers will need to balance two competing goals: scaling up chemical recycling to meet ambitious circular-economy targets, and ensuring that recycled-content claims are credible, traceable, and environmentally meaningful.
