Designing a take-back programme around real return streams
Warranty returns, recall stock, prototype packs and true end-of-life units behave differently. Warranty returns often hold high capacity and may be repairable at module level, while recall stock can be large, sudden and partly damaged. Prototype and validation packs carry confidential designs and need controlled destruction records. End-of-life packs arrive steadily from dealers and fleets with a wide spread of condition.
We map each stream to a route before the first collection: which sites receive it, what paperwork travels with it, who signs off grading and how value is shared. Mapping this early prevents the most common programme failure, where every return is treated as scrap and high-value modules are shredded because nobody set up a faster path for them.
| Stream | Typical condition | Default route |
|---|---|---|
| Line rejects and production scrap | New, off-specification | Separate assay and refining lot |
| Warranty returns | Often high SOH | Diagnosis, repair or second life |
| Recall stock | Mixed, may be damaged | Surge intake with quarantine |
| Prototype and validation packs | Varied, confidential | Controlled teardown and destruction record |
| End-of-life packs | Wide SOH spread | Module grading, then reuse or refining |
Evidence that satisfies regulators and auditors
Producer responsibility is only discharged when the evidence holds up. In India that means certificates generated on the CPCB EPR portal against verified recycled weight. In the EU it means documentation that supports producer responsibility, recycling efficiency and, from February 2027, battery passport records for in-scope batteries. In the United States it means traceability that supports state programmes and customer sourcing requirements.
We tie every certificate to serial numbers, weighbridge records and processing outcomes, so an auditor can follow a pack from the dealer bay to the refined salt batch. Monthly data feeds carry the same records into your ESG reporting, which avoids two versions of the truth.
- Serial-level chain of custody from collection to final outcome
- Weighbridge reconciliation against each manifest
- Per-consignment certificates with downstream vendor disclosure
- Confidential destruction records for prototype hardware
