The BottleneckAmerica doesn't have a lithium shortage. It has a water problem.
Beneath our own soil — in brine and produced water — sits an enormous domestic lithium resource. The barrier was never geology. The stream is simply too dilute to concentrate economically with conventional methods, so it gets pumped back underground as waste while we keep importing.
That single cost — turning dilute brine into a battery-grade product without burning a fortune in energy — is the only problem EEARTH works on. Solve the concentration economics and the rest of the supply chain follows. That is exactly what ELEMENTAL does.
Meet ElementalThe modular lithium refinery.
Lowest cost. Fastest to market. Made in America.
Five containers from brine to battery-grade. A complete refinery that ships on trucks and stands up at the wellhead. Every stage is a proven commercial unit-op, integrated by EEARTH and concentrated by our patented MPVD step.

+Wellhead Pre-Treatment
On raw wellhead brine, an optional front-end runs ahead of Clara — degassing, hydrocarbon and bulk-solids removal, and initial conditioning — so the same modular train delivers battery-grade lithium regardless of feed source.
Container 1
C1.1Clara
Conditioning & Filtration
Raw Smackover tail brine arrives acidic and carrying dissolved iron. Clara lifts the pH with caustic and oxidizes the iron into a filterable solid, then runs two-stage filtration — cartridge followed by ultrafiltration — to drop suspended solids below what the extraction media can tolerate.
Why It Matters: DLE media is unforgiving; iron and solids blind it and shorten its life. Clara protects the most expensive consumable in the train. Get the water right and everything downstream works.
Container 2
C2.1Capta
Direct Lithium Extraction
Technology-agnostic by design: we pilot and select the best DLE chemistry for each brine — sorbent, ion-exchange, or electrochemical. The unit selectively pulls lithium from a brine dominated by sodium, calcium, and magnesium, producing a dilute lithium-chloride eluate while achieving 95%+ lithium recovery.
Why It Matters: We don't bet the company on one DLE vendor — we integrate the best fit for the resource, de-risking both performance and cost. Selectivity here sets the ceiling for the whole train.
Container 3
C3.1Densa
Membrane Concentration
The eluate from Capta is mostly water. Densa does the first concentration lift with brackish-water reverse osmosis — moving water with pressure, not heat.
Why It Matters: Every gallon concentrated with membranes is a gallon we never have to boil. This is the first half of the cost advantage.
C3.2Molla
Softening
Molla chemically softens the stream, dropping bulk calcium and magnesium ahead of the polishing steps.
Why It Matters: Impurities carried into the refinery end up in the product and fail at the customer's gate. Removing the bulk hardness here protects everything downstream.
C3.3Pura
Ion-Exchange Polishing
Pura is two ion-exchange polishing steps that strip residual hardness and boron to trace levels using selective IX media. Boron is a notorious lithium contaminant — it comes out here, resulting in ≥99.5% battery-grade target.
Why It Matters: This is what lets us promise ≥99.5% battery-grade, consistently — not just on a good day.
