Cirba Solutions has completed a closed-loop battery recycling pilot program with General Motors, marking a operational milestone in the automaker's push to keep end-of-life and production-scrap EV battery materials within its own supply chain.

The completion of the pilot moves the partnership from demonstration phase toward commercial-scale execution. Closed-loop arrangements of this type are designed to recover battery-grade materials from scrap and returned packs and return them to cell production, reducing the automaker's exposure to virgin critical-minerals supply. Neither company has yet published tonnage figures or recovered-material volumes from the pilot in the announcement, but the program's conclusion signals that the process chain has run end to end.

For GM, the pilot forms part of a broader materials strategy tied to its Ultium battery platform rollout. For Cirba Solutions, one of the largest battery recyclers operating in North America, a completed closed-loop trial with a major OEM serves as commercial validation of its hydrometallurgical recovery capabilities.

What does a completed pilot actually prove?

In the battery recycling sector, pilots and operating plants are distinct categories. Announced projects frequently outnumber facilities that have processed material at commercial volumes. A pilot that has completed — rather than simply launched — demonstrates three things:

• The recycler can take GM-sourced battery material and process it through its recovery chain.
• The recovered outputs can meet the specifications required to re-enter battery production.
• The logistics, contracting and material-tracking framework between the two companies functions in practice.

Closed-loop deals have become the dominant commercial model in EV battery recycling in North America. Automakers including GM, Ford and others have struck supply agreements with recyclers such as Cirba Solutions, Redwood Materials and Li-Cycle to secure domestic sources of nickel, cobalt, lithium and copper as demand for cell production accelerates.

Why automakers want their scrap back

Production scrap is the near-term feedstock prize. Gigafactory ramp-ups generate significant volumes of electrode trim, reject cells and defective packs years before end-of-life EV batteries arrive in meaningful quantities. Recyclers that lock in OEM scrap streams now build the feedstock base that determines utilization rates at their processing plants.

For the automaker, closed-loop recycling offers a hedge on critical-minerals price volatility and a compliance instrument as battery-material content rules tighten under programs such as the US Inflation Reduction Act's sourcing requirements.

Cirba Solutions operates recycling capacity at multiple North American sites and has announced expansion projects intended to scale recovered-material output toward the volumes that automotive supply contracts demand. The company's ability to convert pilot results into contracted, tonnage-backed supply agreements will determine whether the GM partnership becomes a template or stays a demonstration.

What happens next

The watch items now are commercial ones: whether GM and Cirba Solutions convert the pilot into a long-term offtake or scrap-supply agreement, and whether the companies disclose recovered-material volumes that would allow the market to benchmark recovery rates and unit economics against competitors. Sector peers have set 2025 and 2026 deadlines for commissioning scaled recycling capacity, and OEM contracts increasingly hinge on demonstrated throughput rather than pilot-stage results. The next disclosure of tonnage from this partnership is the milestone that will show whether the loop stays closed.
