10. Method for verifying rates of recycling efficiency and recovery of materials from waste batteries

• (1) Verification of the rates of recycling efficiency and recovery of materials from waste batteries, as documented by the first recycler, shall cover at least the following areas:

• — documentation;

• — data confidentiality;

• — verification techniques.

• (2) Verification of the overall calculations shall be carried out by the competent authority (or authorities) of the Member State in which the waste battery treatment is performed. That authority shall forward relevant data [^ntr2-L_202500606EN.000301-E0002] to the Member States in which the waste batteries were collected (if different).

• (3) Documentation shall be provided by the first recycler to the competent authority (or authorities) of the Member State in which the waste battery treatment is performed, in accordance with the following requirements:

• — the layout for the documentation shall comply with the templates set out in sections 6 to 9. In particular, it shall cover, in a comprehensive and structured way, all individual steps of the waste battery recycling, i.e. all recycling facilities involved, but not the individual recycling operations carried out within one facility, and the corresponding input, intermediate and output fractions, in accordance with Article 75(5) of Regulation (EU) 2023/1542;

• — the format of the documentation shall be electronic, and it shall be such to be handled through world-deployed software.

• (4) Where waste holders other than waste management operators carrying out treatment and recyclers export batteries for treatment, verification shall be carried out by the competent authority of the Member States in which those waste holders exporting the waste batteries are located.

• (5) The competent authority (or authorities) shall treat all the data and information examined for the verification procedures confidentially and shall use them only for the verification procedure itself.

• (6) The competent authority (or authorities) shall apply at least the following techniques for verification:

• — verification of the completeness, accuracy and consistency of the overall calculations and information contained in the documentation (see sections 6 to 9);

• — for batteries that are wholly or partly recycled outside the EU, verification that documentary evidence, approved by the competent authority of the destination country, that the recycling took place under conditions that are equivalent to those required by Regulation (EU) 2023/1542 and in accordance with other Union law regarding human health and environmental protection, has been provided;

• — aggregation and verification of the consistency and completeness of all the data supplied by the various first recyclers.

• (7) The competent authority (or authorities) may also verify the accuracy, reliability and traceability of the recycling and the corresponding rates provided by requesting evidence from relevant parties in the recycling chain (such as a contract, transportation document, or contact details of other recyclers in the recycling chain) documenting the existence of the flows during the documentation period. The competent authority (or authorities) may also carry out verification by auditing relevant parties in the recycling chain, in accordance with the decisions of the Member States. In any case, this shall not exclude visits to recycling facilities as part of the auditing procedure.

• (8) Recyclers may also carry out self-auditing through external companies. In this case, recyclers may provide the competent authority (or authorities) with the results of the auditing process at the time of the minimum verification. If notified of the results, the competent authority (or authorities) shall fill in the appropriate section on verification in the corresponding documentation (see sections 6 to 9).

• (9) Verification of the overall calculations and information shall be carried out every calendar year, on the basis of the documentation provided by first recyclers (see sections 6 to 9). Additional verification techniques referred to in point (7) may be carried out whenever requested by the competent authority (or authorities) of the Member State. Self-auditing referred to in point (8) may be carried out by recyclers whenever they find it appropriate.

• (10) After, at least, the minimum verification and before forwarding the verified documentation to the Member State in which the waste battery was collected (if different), the competent authority (or authorities) shall properly complete the documentation indicating the number of verification techniques carried out.

• (11) The verification may be carried out per battery chemistry (lead-acid, lithium-based, nickel-cadmium, others) or per specific chemistry of the different families.
