Battery recycling efficiency in the EU: the 31 December 2025 deadline is coming

From 31 December 2025, every battery recycler operating in the European Union will have to prove that they meet the new minimum recycling efficiency targets set by the EU Battery Regulation (Regulation (EU) 2023/1542) and its new delegated act on calculation methodology.

The battery recycling efficiency EU 2026

It cares about how we measure the real performance of plants recycling lithium-ion, lead–acid, nickel–cadmium and other battery chemistries, and how that information is reported to authorities in a comparable, EU-wide way.

In this article we give you a quick refresher, with a practical focus, and explain how Revive Batteries helps translate these legal requirements into real-world processes, data and contracts.

1. Quick refresher: what does the EU Battery Regulation require?

Annex XII of Regulation (EU) 2023/1542 sets minimum recycling efficiency targets by weight that recyclers must achieve no later than 31 December 2025:

• 75% for lead–acid batteries
• 65% for lithium-based batteries
• 80% for nickel–cadmium batteries
• 50% for other types of batteries

These targets increase by the end of 2030 for some chemistries:

• 80% for lead–acid
• 70% for lithium-based batteries

In parallel, the Regulation sets material recovery targets for critical raw materials from 31 December 2027 and again from 2031 onwards, focusing on cobalt, copper, nickel, lead and lithium:

• For 2027:
  • 90% for cobalt, copper, lead and nickel
  • 50% for lithium
• For 2031:
  • 95% for cobalt, copper, lead and nickel
  • 80% for lithium

In short: the EU doesn’t only want you to “recycle a lot”; it wants you to prove with robust data that you are recovering critical materials efficiently and in a way that truly displaces primary raw materials.

2. The missing piece: Delegated Regulation (EU) 2025/606

So far, we knew what targets had to be met. What was missing was a precise, harmonised description of how to calculate and verify them. That is exactly the purpose of Delegated Regulation (EU) 2025/606, published on 4 July 2025 and applicable from 24 July 2025.

This delegated act:

• Defines a mandatory methodology to calculate:
  • recycling efficiency (rRE), and
  • material recovery rates (rRM)
• Specifies what is in and what is out of the input stream and which output fractions can be counted.
• Introduces a harmonised documentation format that recyclers must submit to national authorities.
• Strengthens traceability requirements: recyclers must document the fate and performance of final fractions, especially those containing critical or sensitive substances.

The political and market objectives are clear:

• Avoid unfair competition between recyclers due to different calculation methods.
• Ensure that only those output fractions are counted which genuinely substitute primary raw materials in downstream value chains.

3. What does this mean in practice for recyclers and producers?

Beyond the legal language, these changes have very concrete consequences for anyone involved in the management of waste batteries.

3.1. Getting battery flows classified correctly

Recycling efficiency is calculated by battery type:

• Lead–acid
• Nickel–cadmium
• Lithium-based
• “Other” batteries

This means you need tight control over:

• How you segregate flows from collection through pre-treatment.
• How you handle mixed chemistries (for example in complex waste streams) without compromising data quality.

3.2. Much more granular process data

The methodology goes into detail on:

• Measurement points within the recycling process.
• Which fractions can be considered recycled output or recovered materials.
• How to treat:
  • water streams, sludges, casings, black mass, metallic fractions, etc.

If you were used to fairly “macro” reporting, the required level of granularity now clearly increases.

3.3. Risks of double counting and accidental greenwashing

With cross-border flows and cascading contracts (pre-treaters, refiners, etc.), there is a real risk of:

• double counting the same fraction, or
• misclassifying inputs

Authorities and auditors will scrutinise:

• The consistency between declared tonnages and authorised capacity.
• The consistency between fractions sent to other recyclers and the efficiency data those partners report.

In other words, methodological sloppiness can quickly look like greenwashing, even if it wasn’t intentional.

3.4. Direct impact on contracts and client relationships

For producers, collective schemes and other partners, these changes translate into:

• A need to update contracts to:
  • secure access to process data, and
  • include reporting and verification clauses.
• Increased pressure to choose partners who can demonstrate compliance, not just claim it in marketing materials.

Those who do not adapt in time may find themselves excluded from the value chain, especially in tenders or supply agreements tied to ESG criteria and the battery passport.

4. Where does Revive Batteries add value?

At Revive Batteries, we work precisely at the intersection of operations, smart reverse logistics and European battery regulation. That allows us to support recyclers, producers and collective schemes in moving from legal text to implementable solutions.

Some concrete ways we can help:

• Regulatory and process mapping
  • Translating the requirements of Regulation (EU) 2023/1542 and Delegated Regulation (EU) 2025/606 into real-world flows for lithium-ion and other battery chemistries.
• Data and traceability design
  • Defining measurement points, data structures and evidence packages needed to comply with:
    • recycling efficiency targets, and
    • critical raw material recovery targets.
• Optimising reverse logistics and pre-treatment
  • Adjusting reverse logistics for waste batteries and pre-treatment operations to:
    • improve yields,
    • reduce material losses,
    • minimise safety risks and costs.
• Support with audits and authorities
  • Preparing documentation in the harmonised format required by the new rules.
  • Providing technical support in interactions with auditors and national authorities.

In short: we don’t just know the regulation; we design and operate circular value chains that comply with it.

5. Recommended next steps before 31 December 2025

If you are a recycler, producer or manage waste batteries in Europe, we strongly recommend:

1. Quick diagnostic
   • Assess whether your processes, data and contracts are ready for:
     • the 2025 recycling efficiency targets, and
     • the 2027/2031 material recovery targets.
2. Data and metrology review
   • Make sure you are measuring the right parameters, at the right points, with sufficient data quality.
3. Contract review with partners
   • Ensure you have the right to access the data that the regulation now requires.
4. Communication strategy
   • Turn compliance into a competitive advantage: show your customers that your battery recycling and critical material recovery solutions are fully aligned with the new EU framework.
