Redwood Materials expands Rivian deal to scrap and end-of-life packs

Redwood Materials will recycle both battery manufacturing scrap and end-of-life packs from Rivian, and supply energy storage for the automaker's manufacturing plant, under an expanded partnership announced by the two companies.

The agreement widens a relationship that until now centred on end-of-life vehicle batteries. It now covers the full material stream a battery producer generates: production scrap from the factory floor, retired packs coming off vehicles, and storage capacity that loops back into the plant itself.

What does the expanded scope cover?

According to the announcement, Redwood Materials will handle three streams for Rivian:

• Manufacturing scrap — electrode, cell and pack waste generated during production, which Redwood refines back into battery-grade nickel, cobalt, lithium and copper feedstock.
• End-of-life packs — batteries retired from Rivian vehicles at the close of their service life.
• Energy storage — Redwood will provide storage for Rivian's manufacturing plant, pairing recycling logistics with stationary capacity on the industrial side.

The combination matters because scrap is the near-term volume problem. A new battery plant typically produces more scrap tonnage in its early ramp years than it does failed field returns, and that scrap is high-purity material that loses value if it is downgraded rather than returned to battery-grade supply chains.

By folding Rivian's scrap and retired packs into one channel, Redwood consolidates feedstock for its refining output. The takeaway is simple: this is a supply agreement dressed as a sustainability announcement.

Why pair recycling with plant storage?

The storage element is the newer signal. Redwood Materials has positioned itself not only as a recycler but as a producer of energy storage built around recovered materials, and an automaker customer now doubles as a storage offtaker.

For Rivian, storage at the manufacturing plant serves two conventional purposes: managing demand charges and buffering renewable supply against production schedules. The announcement does not specify the storage capacity, chemistry or commissioning date, so the built-versus-announced distinction remains open. The companies said only that Redwood will provide energy storage for the plant.

The one-line read: recycled material flowing one way, stored electrons flowing the other.

What has Redwood said about the deal?

The companies framed the expansion as a natural extension of their existing work on end-of-life batteries. Redwood Materials described the arrangement as covering both the waste stream and the energy side of Rivian's operations — recycling scrap and end-of-life packs while providing storage for manufacturing.

No tonnage figures, contract duration or financial terms appear in the announcement. Those numbers, when they surface in filings or subsequent statements, will determine whether this is a marginal logistics arrangement or a meaningful share of Redwood's inbound feedstock.

What decides what happens next?

Two things. First, volumes: Rivian's production ramp governs how much scrap and how many retired packs actually move through the channel, and neither company has quantified the expected tonnage. Second, Redwood's refining capacity on the output side — recycled feedstock only counts if it re-enters battery-grade supply at scale.

Watch for the first disclosed volume or capacity figure attached to this partnership. That number, not the press release, will say whether the deal moves material or merely moves headlines.
