The problem with black mass and how GreenLIB solves it
Feedstock variability
Black mass varies by battery source (EVs, storage, consumer electronics), chemistry, and shredding method. GreenLIB’s modular process handles this variability with thermal decomposition, gas removal, and solid separation to ensure consistent processing.
Fluorine contamination
Fluorinated compounds from PVDF binders and LiPF₆-based electrolytes lead to refining inefficiencies and safety risks. Our process thermally decomposes organofluorines and uses selective gas-phase capture and scrubbing to remove fluoride species before downstream hydrometallurgy.
Electrolyte risks
Volatile organic solvents and decomposition products (like HF, PF₅) complicate material handling and reduce refining efficiency. We remove these in an early-stage controlled atmosphere step, mitigating fire hazards and reducing mass balance uncertainty for lithium recovery.
Material separation
Delivers clean fractions—high-purity graphite, lithium carbonate, and Ni/Co-rich solids with minimal Al, F, or P contamination, ready for efficient refining.

Full Material Return
For EV OEMs, battery manufacturers, and cell producers who want full material traceability and access to high-purity recovered Ni, Co, Li, graphite, and other elements. You get everything back — we handle the complexity.
Ni/Co-Only Return
Designed for shredders, MHP producers, metal scrap yards, and logistics partners looking to enhance their Ni/Co payables without dealing with lithium, graphite, or aluminum. We refine the black mass, return the Ni/Co, and retain the rest.
Custom Allocation
For strategic partners with specific recovery or offtake goals — including MHP producers, refiners, or battery value chain integrators. Choose what you keep, define your yield profile, and we tailor the economics accordingly.
Advantages over conventional methods
Engineered to exceed EU and North American emissions standards for fluorine and organics, ensuring safe and compliant operations.
Black mass agnostic – works across chemistries, formats, and blends. Drop-in modular design integrates easily before existing refining lines—no need to reengineer your plant.
Reduces total refining costs by delivering cleaner feedstock, lowering reagent use, and minimizing off-gas treatmer.
