Mature parts. Proprietary sequence.
Caelumetrics is a zero-liquid-discharge brine refinery. Every unit operation inside it is commercially proven and in service somewhere in industry today. The invention is the order they run in — the integrated sequence that turns a toxic, mixed-salt waste stream into clean water and separated, battery-grade products with nothing left over.
Principles, not the recipe.
What the system does — not the staged architecture that does it.
Closed-loop reagents
Reagents are regenerated and reused on-site rather than purchased and discarded, which is what lets the unit economics close on a waste feedstock.
Behind-the-meter renewable
Designed to run on co-located renewable generation, decoupling operating cost from grid prices and lowering the carbon footprint of every product.
Carbon-negative by design
Captured CO₂ is consumed inside the process and fixed into saleable products — the refinery removes more carbon than it emits.
Zero liquid waste
Every input leaves as water or product. There is no reject brine, no injection well, no tailings pond at the end of the line.
Proven components, validated design, bench-scale next.
Caelumetrics did not invent new chemistry. The refinery is assembled from unit operations that are individually mature and operating at commercial scale across the water, chemical, and minerals industries today — which removes the science risk that sinks most deep-tech.
The integrated system — the specific sequence and the closed reagent loop that make it work as one machine — is the company's intellectual property, and it is being validated at bench scale on real feedstock. The design is anchored to a 54-sample characterization of actual Permian brine, not a generic model.
Yields and economics presented in diligence are modeled from that validated design and characterization. They are clearly labeled as such; the company makes no claim of operating-plant data it does not yet have.
