Europe is moving into a new phase of battery recycling regulation, shifting the focus from ambitious circular-economy targets to a more difficult question: how manufacturers will prove the recycled content they claim is actually present in batteries sold on the EU market.
A new study by the European Commission’s Joint Research Centre (JRC), published on 13 July 2026, proposes the technical framework that could determine how companies calculate, document and verify recycled cobalt, lithium, nickel and lead in batteries. Commissioned by the Commission’s DG Environment and DG GROW, the study is intended to support the forthcoming delegated act under Article 8 of the EU Batteries Regulation, Regulation (EU) 2023/1542.
The significance of the proposal lies not primarily in setting new recycling targets. Those targets already exist. The more consequential issue is defining what qualifies as recycled material, where recycled content must be measured, how it can be allocated across products and what evidence companies will need to produce during an audit. The resulting framework could affect battery manufacturers, recyclers, refiners, cathode-material producers, automotive companies, energy-storage developers and importers throughout Europe and beyond.
EU Battery Rules Will Apply Across Global Supply Chains
The requirements will cover electric-vehicle batteries, light means of transport batteries, starting, lighting and ignition batteries, and industrial batteries above 2 kWh, including most commercial and utility-scale battery-energy-storage systems. Importantly, the rules will apply to batteries placed on the EU market regardless of where they were manufactured. A battery produced in Germany, Hungary, China, South Korea, Serbia or another non-EU jurisdiction will face the same fundamental documentation requirements once it enters the European market. From 18 August 2028, or 24 months after the delegated act enters into force, whichever occurs later, covered batteries containing cobalt, lead, lithium or nickel will have to include documentation showing the quantity of those metals recovered from battery-manufacturing waste or post-consumer waste.
The calculation differs depending on the material. For cobalt, lithium and nickel, the methodology applies to the metals contained in active materials. For lead, the calculation concerns the proportion of lead in the battery originating from waste. The methodology will therefore need to accommodate different battery chemistries, manufacturing processes and material boundaries while preventing manufacturers from selecting whichever calculation produces the most favourable recycled-content figure.
Mandatory Recycled-Content Targets Begin in 2031
The first binding thresholds will apply from 2031.
Covered batteries will need to contain at least:
- 16% recycled cobalt
- 85% recycled lead
- 6% recycled lithium
- 6% recycled nickel
From 2036, the requirements increase to:
- 26% recycled cobalt
- 85% recycled lead
- 12% recycled lithium
- 15% recycled nickel
These targets mean that accounting accuracy will become almost as important as access to recycled metals. A manufacturer may have access to recycled material, but if it cannot demonstrate the origin, quantity, processing route and allocation of that material, the recycled content may not be usable for regulatory compliance.
From a Percentage on Paper to a Complex Industrial Chain
A recycled-content declaration appears straightforward when expressed as a percentage. The physical supply chain is considerably more complicated. End-of-life batteries and manufacturing scrap are typically discharged, dismantled and mechanically processed into black mass.
That intermediate material can contain lithium, nickel, cobalt, manganese, graphite and other materials.
Black mass may then cross borders, be blended with material from other sources and undergo hydrometallurgical or pyrometallurgical processing before recovered metals are converted into battery-grade salts, precursors or cathode active materials. By the time a refined material reaches a cell manufacturing facility, its physical connection to an individual discarded battery may no longer be possible to reconstruct. Battery plants also routinely mix virgin and recycled feedstocks, maintain inventories across multiple accounting periods and manufacture several products using shared equipment.
Some outputs may fall under Article 8 while other materials produced through the same facilities may be sold into applications outside the regulation. That creates the central challenge for the European Commission: how can recycled attributes remain credible while allowing modern battery and chemical plants to operate efficiently?
Chain of Custody Becomes a Regulatory Requirement
The JRC study places significant attention on chain of custody. This is the system that connects a recycled input and its associated environmental attribute to the battery carrying the final recycled-content claim. The report examines different approaches, including the balance between strict physical traceability and more flexible mass-balance accounting. The options are assessed against criteria including business continuity, material efficiency, climate impact, consumer confidence, verifiability and administrative costs.
At the most physically rigorous end of the spectrum, recycled material is followed through controlled production and blending. The recycled percentage remains closely linked to material entering a specific process or product group. This provides stronger assurance that a battery contains the claimed recycled content, but it can also require separate storage, production planning and inventory controls. For global supply chains, strict physical segregation could force companies to separate chemically identical materials or move products over longer distances simply to preserve documentary traceability.
Mass Balance Offers Flexibility but Creates Verification Risks
A mass-balance system provides greater industrial flexibility. Recycled and virgin materials can be physically mixed, while the recycled attribute is allocated through an accounting system covering a defined plant, product group and balancing period. This approach is closer to operating models already used in parts of the chemical and battery-materials industries. It can reduce production disruptions and allow recyclers to process materials where recovery is technically and economically most efficient.
The main concern is credibility. An excessively flexible credit system could separate the recycled-content claim from the physical product. For example, a producer could allocate a high recycled-content percentage to a premium battery line while assigning little or no recycled content to another product, even though both were manufactured from the same blended feedstock. The overall accounting could remain mathematically balanced while the individual purchaser receives a battery with no obvious physical connection to the recycled inputs. That is why preventing double counting and unsupported allocation will be one of the most important elements of the final EU methodology.
Auditable Data Will Become Part of Battery Manufacturing
The JRC has developed detailed calculation and verification approaches for two traceability models rather than presenting one system as free from trade-offs. The regulatory challenge is to retain enough flexibility for industrial production without permitting:
- double counting of recycled material
- artificial concentration of recycled attributes
- unsupported transfer of credits
- allocation between unrelated plants
- manipulation of accounting periods
- claims that cannot be independently verified
The practical requirements will extend far beyond a certificate issued at the end of manufacturing. Companies will need auditable evidence covering the origin and classification of waste, material received, processing yields, recovered-metal quantities, inter-facility transfers, inventory movements and allocation to battery models or product groups. Records will also need to identify calculation periods, production losses, inventories carried between accounting periods and any recycled-content attributes transferred with intermediate materials. The result is a fundamental change in the meaning of recycled material. Verified recycled material could become a separate commercial product category.
Procurement Contracts Will Need New Data Requirements
Battery manufacturers will not be able to produce reliable Article 8 declarations if their suppliers provide only generic sustainability certificates. Procurement contracts are therefore likely to require increasingly detailed information, including: defined datasets, calculation methodologies, audit rights, document-retention requirements and contractual liability for inaccurate recycled-content claims.
This could change commercial relationships throughout the battery supply chain. A cell producer may need information from a cathode-material supplier, which in turn may require information from a precursor producer, refiner and recycler. The result is a multi-tier chain of evidence extending far beyond the immediate supplier relationship.
Verified Recycled Metals Could Command a Premium
The distinction between recycled material and verified recycled material could eventually become commercially significant. Chemically identical nickel sulphate or lithium carbonate may have different market values depending on whether the supplier can prove its waste origin, processing history and chain of custody.
Recyclers capable of delivering battery-grade materials together with complete and auditable documentation could therefore gain a competitive advantage. They may be better positioned to secure long-term offtake agreements with European battery manufacturers and automotive companies seeking reliable compliance with EU rules. The value proposition of a recycling plant will increasingly include not only recovery rates and operating costs, but also data quality and regulatory traceability.
European Recycling Capacity Is Expanding
The regulatory changes are arriving as Europe builds its battery-recycling infrastructure. BASF’s Schwarzheide black-mass plant in Germany, which entered commercial operation in June 2025, has the capacity to process up to 15,000 tonnes of end-of-life lithium-ion batteries and production scrap per year, equivalent to approximately 40,000 electric-vehicle batteries. The facility forms part of BASF’s wider battery-materials network, connecting black-mass processing, metal recovery and cathode-material production more closely than a fragmented trading chain.
Mercedes-Benz’s Kuppenheim recycling plant has annual capacity of approximately 2,500 tonnes and an expected recovery rate of more than 96%. Recovered materials are intended to support the production of more than 50,000 battery modules. Its integrated mechanical and hydrometallurgical process represents the type of closed-loop structure in which physical material flows and recycled-content declarations can potentially be reconciled more directly.
In Norway, Hydrovolt’s Fredrikstad facility can process approximately 12,000 tonnes of battery packs annually, equivalent to around 25,000 electric-vehicle batteries. Such facilities will increasingly compete not only on gate fees, recovery rates and processing costs, but also on their ability to generate verified recycled material and transferable chain-of-custody information.
Battery Recycling Faces a Feedstock Challenge
The rules are being introduced while Europe remains highly dependent on imported batteries. JRC data indicate that in 2024, more than 85% of batteries imported into the EU originated in China. At the same time, EU manufacturing capacity was sufficient to cover only approximately 21.4% of estimated EU battery requirements for 2030, despite improving by 4.2 percentage points from the previous year. Under the EU’s Net-Zero Industry Act, the policy objective is to develop domestic manufacturing capacity capable of meeting at least 40% of annual deployment requirements by 2030. Recycling alone cannot close that manufacturing gap in the near term.
Today’s electric-vehicle batteries will remain in service for years, and some battery packs may enter second-life applications before ultimately reaching recycling plants. During the early compliance period, manufacturing scrap could therefore represent a significant share of available secondary feedstock. Post-consumer battery volumes are expected to increase later as Europe’s electric-vehicle fleet becomes older.
2031 Targets Could Face a Feedstock Reality Check
The timing is particularly important for the economics of the 2031 recycled-content targets. A recycler may have substantial nominal processing capacity but insufficient feedstock to operate efficiently. Battery chemistry is another major variable. The growing adoption of lithium iron phosphate (LFP) batteries reduces the amount of cobalt and nickel contained in each tonne of battery waste while maintaining the strategic importance of lithium recovery.
Recycling businesses designed around revenues from nickel and cobalt may therefore need to adjust their economics as LFP batteries account for a larger share of the market. Possible responses could include higher gate fees, revised operating models or long-term supply agreements with battery manufacturers and vehicle producers.
Different Battery Chemistries Face Different Compliance Risks
The EU rules will affect battery technologies differently. Lead-acid batteries already operate within a mature recycling ecosystem. The 85% recycled-lead target is demanding, but it is comparatively aligned with established industrial recycling practices. Nickel-manganese-cobalt batteries face more extensive documentation requirements because several metals fall under the recycled-content framework.
LFP batteries avoid the cobalt and nickel requirements but remain subject to the recycled-lithium target and the broader chain-of-custody requirements. The result is a regulatory framework in which battery chemistry will increasingly influence not only material costs and performance, but also recycling economics and compliance exposure.
Battery Storage Projects Will Face New Procurement Requirements
The consequences will extend beyond electric vehicles. Utility-scale and commercial battery energy storage systems (BESS) generally use industrial batteries well above the 2 kWh threshold. Developers, lenders and Owner’s Engineers will therefore need to ensure that battery-supply agreements address Article 8 requirements. Contracts may need to include: recycled-content documentation, access to supporting records, audit rights and contractual remedies for non-compliant equipment.
A battery system can remain technically operational even if its compliance evidence is incomplete. The commercial consequences could nevertheless be significant. Potential problems include delayed acceptance, restrictions on placing equipment on the EU market, replacement obligations, financing conditions and disputes over responsibility for regulatory changes. Recycled-content compliance is therefore becoming another interface between technical specifications, supply-chain due diligence and project bankability.
Non-EU Manufacturers Face the Same Burden
Manufacturers outside the European Union will not escape the evidentiary requirements. A battery assembled outside the EU cannot simply rely on a local recycling certificate if the underlying calculation methodology does not correspond with the European delegated act. Manufacturers will need traceability across multiple stages, potentially involving: recyclers, refiners, precursor producers, cathode-material manufacturers, cell plants and final assembly facilities.
EU importers may increasingly demand contractual access to documentation several tiers upstream, including records maintained outside the European regulatory system. This could make supply-chain transparency a competitive requirement for Asian and other international battery manufacturers seeking European customers.
Serbia and the Western Balkans Face Both Risk and Opportunity
For Serbia and the wider Western Balkans, the emerging framework creates both a compliance challenge and an industrial opportunity. Battery, component and raw-material projects seeking access to European automotive and energy-storage supply chains will increasingly need to incorporate EU-compatible material accounting and traceability systems from the beginning of project development.
The EU-Serbia strategic partnership covering sustainable raw materials, battery value chains and electric vehicles provides a broader policy framework for closer integration. Participation in European supply chains will ultimately depend on practical factors at plant level. Companies will need to demonstrate verifiable material flows, reliable datasets, auditable accounting and importer-ready documentation. For regional producers, building these systems early could become a competitive advantage rather than simply a regulatory expense.
The EU Must Balance Traceability With Industrial Efficiency
The JRC study does not remove the fundamental tension between physical traceability and industrial flexibility. Instead, it makes the trade-off explicit. An excessively rigid system could increase costs, fragment inventories and discourage efficient recycling.
An overly flexible mass-balance system, on the other hand, could reduce the 2031 and 2036 thresholds to accounting claims with limited connection to the physical batteries purchased by European consumers and energy-storage developers. The final delegated methodology will determine where that regulatory boundary is drawn. Its impact could extend well beyond compliance departments. The framework will influence recycling investment, battery procurement, raw-material contracts, plant design, supply-chain management and financing decisions across Europe.
Recycled Content Is Becoming a Data and Compliance Asset
The European battery market is moving toward a model in which recycled material must be not only physically recovered, but also measurable, traceable and legally defensible. The companies best positioned for the next phase of the EU battery economy may therefore not simply be those with the largest recycling capacity. They will be the companies capable of combining high recovery rates with reliable chain-of-custody systems, auditable data and commercially transferable recycled-content attributes.
For battery manufacturers, recyclers, refiners and raw-material suppliers, the strategic message is increasingly clear. The future value of recycled lithium, nickel, cobalt and lead will depend not only on how much material can be recovered, but on whether its origin and recycled status can be proven. As the EU moves from recycling targets to auditable compliance, data quality and material traceability are becoming part of the battery product itself.
