GreenLib provides a Refinement-as-a-Service platform that thermally pre‑treats battery black mass to remove fluorine, binders and chemistry variability, delivering a high‑purity feedstock for downstream refiners. The modular, flat‑fee service lets EV OEMs, battery makers and recyclers increase metal recovery above 95% while avoiding capital investment and reducing operating costs.

Problem
Battery recycling faces low yields and high costs because the incoming black mass is often contaminated with fluorine, binders, and inconsistent chemistries, making downstream refining inefficient and expensive.
Solution
GreenLib offers a Refinement-as-a-Service (RaaS) platform that thermally pre‑treats black mass to remove contaminants and standardize feedstock. The service is delivered as a flat‑fee, modular process that requires no capital investment or engineering effort from customers. By upgrading black mass to a high‑purity material, GreenLib enables downstream refiners to achieve over 95% recovery of nickel, cobalt, lithium, graphite, and other elements while reducing CAPEX and OPEX. The model also increases material payables by up to 40% and provides transparent tracking of recovery performance.
Target Audience
Primary customers are EV OEMs, battery manufacturers, cell producers, shredders, metal‑hydride producers, and scrap yards that need low‑CAPEX, high‑yield pre‑treatment for black mass.
Features
- Thermal pre‑treatment that eliminates fluorine, binders, and variability across all major battery chemistries (LFP, NMC, NCA, LCO)
- Modular, scalable units that can be sized from pilot to industrial throughput without customer‑owned infrastructure
- Flat‑fee pricing with transparent recovery metrics and real‑time tracking
- Over 95% recovery efficiency for nickel, cobalt, lithium, graphite, and additional metals
- Options for full material return, nickel/cobalt‑only return, or custom allocation to match partner offtake goals
