Oxalate/formate-based mineral recovery chemistry within scope for 26-PH1?
For topic 26-PH1, would a chemical process focused on improving recovery of rare earth / critical minerals from end-of-life lithium-ion battery materials be considered responsive if it uses low-carbon oxalate/formate-based precipitation chemistry?
Specifically, we are considering a Phase I concept to demonstrate selective precipitation/recovery of representative critical minerals from battery-recycling streams, benchmarked against conventional oxalic acid/oxalate routes, with attention to safer handling and improved recovery economics.
Or is this topic primarily focused on residual-energy removal / battery de-energizing technologies rather than downstream mineral recovery chemistry?

As a transportation safety agency, PHMSA’s primary objective for topic 26-PH1 is to reduce the costs and hazards associated with transporting end-of-life lithium-ion batteries from collection points to recycling facilities. While the long-term goal is to support the viability of critical mineral recovery, the specific focus of this solicitation must be on reducing transportation barriers and logistics costs while maintaining a high level of safety during transit. While we do not preclude solutions that also have downstream mineral recovery benefits, the solution must address residual energy removal/battery de-energizing techniques in order to meet this topic's requirement.
