Vertical Integration of Battery Recycling
Redwood Materials
This signals that recycling is becoming part of battery manufacturing infrastructure, not a separate cleanup service. Panasonic’s relationship with Redwood shows the logic. Scrap from cell production in Nevada is collected, processed into battery materials, and sent back into nearby battery plants as copper foil and cathode inputs. That shortens supply lines, lowers raw material risk, and turns factory waste into feedstock for the next batch of cells.

The clearest example is Panasonic in Nevada and Kansas. Redwood has recycled scrap from Panasonic’s Nevada cell production since 2019, and Panasonic later agreed to buy Redwood’s recycled copper foil for Sparks and cathode material for Kansas. This is vertical integration in practice, even if Redwood remains a specialist partner rather than an internal division.

The workflow matters. Battery factories generate large volumes of off spec electrodes, trimmings, and other scrap before a battery ever reaches a car. Putting recycling close to production lets a manufacturer recover nickel, cobalt, lithium, and copper from that scrap quickly, then feed those materials back into new cells with less shipping and fewer intermediaries.

That changes who competes with whom. Pure recyclers mostly extract raw materials from used batteries, while integrated players like Redwood move further downstream into copper foil and cathode production. Once recycling and component manufacturing sit in the same loop, the winner is not just the best processor, but the company best embedded in gigafactory operations.
The market is heading toward battery campuses where scrap handling, refining, and component production sit next to cell lines. As more North American plants come online, recycling will increasingly be designed into factory layouts and supplier contracts from day one, which favors companies that can plug directly into production and return battery grade materials at scale.
