Technology & Process Development
Eryvium develops the process technology that takes raw inputs to exacting purity — demanding science that reaches across a range of high-purity metals and materials. High-purity manganese sulphate is the first we are bringing to commercial scale.
Research & Development at the Core
Eryvium was founded by chemistry professors, doctorate-level scientists, and process engineers. That shapes how the company works: every product begins as a research problem — solved at the bench, proven through controlled development, then engineered for commercial scale.
The result is a repeatable discipline: control impurities to demanding levels, deliver material to an exact specification, and prove it. That discipline is the company’s foundation.
A Capability That Extends Further
The same science underlies many of the high-purity inputs modern technology depends on — in batteries, electronics, and advanced industry. Eryvium’s first commercial focus is high-purity manganese sulphate, but the expertise behind it reaches across a range of high-purity metals and materials: a foundation built to do more than one thing, developed in Europe and the United States with a low-carbon process at its core.
Our Approach
Eryvium’s work is guided by a consistent set of principles — the discipline behind every process the company develops.
- Science before scale. Every process is understood at a fundamental level and proven in the laboratory before any commitment to production.
- Proof over claim. Results are validated through governed development runs and verified by independent accredited laboratories — not asserted.
- Purity by design. Impurity control is engineered into the process from the first principle, not corrected at the end.
- Clean by intention. Processes are designed for low waste, low reagent intensity, and a low-carbon footprint from the outset.
- Built to repeat. The same disciplined method applies across a range of high-purity materials — a capability, not a one-off.
Our Development Capability
From laboratory research through to commercial-scale engineering.
- Competence in high-purity manganese sulphate for battery-grade and ultra-high-purity production
- Impurity control to parts-per-million targets
- Consistent delivery of material to a defined product specification
- Feed and product characterisation and analytical control
- Process design and scale-up from laboratory to commercial output
Process Research
Eryvium’s scientific team designs process routes to achieve target purity and impurity profiles, working from defined feedstock to a specified product.
Controlled Development
Processes are proven through governed development runs that confirm consistency and performance before any commitment to scale.
Commercial Scale-Up
Validated processes are engineered for commercial production through established manufacturing partners — moving from proven chemistry to delivered product.
From Concept to Commercial
A disciplined path from research to delivered product.
Research
Define the purity target and design the route
Bench Validation
Prove the chemistry at laboratory scale
Pilot & Development Runs
Confirm consistency through governed batches at pilot scale
Accredited Verification
Independent ISO/IEC 17025 laboratory testing
Commercial Scale-Up
Engineer to production through an asset-light route
For HPMSM, Eryvium has carried this path from research through pilot and accredited verification, and is now moving into commercial scale-up — the method proven before it is scaled.
Proven in Practice: HPMSM
Eryvium’s first commercial application of its process technology is high-purity manganese sulphate (HPMSM). The process has been proven at pilot scale, verified by independent ISO/IEC 17025-accredited laboratories, and is now advancing toward first commercial output through an asset-light production route. It is concrete evidence that the science holds — not a concept, but a demonstrated result moving to scale.
The HPMSM Programme delivers battery-grade material at 99.98% and an ultra-high-purity grade at 99.99% (4N), upgraded from industrial-grade feedstock for NMC, manganese-rich, and LMFP cathode applications.
- Battery-grade and ultra-high-purity quality for NMC, manganese-rich, and LMFP cathodes
- Clean industrial-grade feedstock with lower environmental impact
- Scalable production with regional supply security (US and Europe)
Built on Science, Built Clean
Eryvium’s development approach is engineered for clean operations and disciplined, defensible results.
Business Benefits
A science-led method delivers products that meet specification consistently, qualify faster with customers, and scale with confidence.
Proven Before Scaled
Processes are validated before any commitment to production.
Specification Consistency
Material held to defined technical requirements, batch to batch.
Faster Qualification
Documented, accredited results speed customer qualification.
Asset-Light Path
Production through established partners, not greenfield build.
Clean by Design
Low-waste, low-footprint chemistry aligned to EU standards.
ESG Impact
Eryvium’s processes are designed for minimal environmental impact:
ENVIRONMENTAL ADVANTAGES:
- Near-zero-waste objective through residue valorisation
- No mine, no tailings, no leach residue
- Low reagent intensity and small operational footprint
- Modelled process emissions ~0.50–0.60 kg CO₂e/kg HPMSM (plant-only basis)
- Progressing toward ISO 9001 / ISO 14001
- Rebuilding Western capability in high-purity battery materials, close to the customers who need it.
