Ohreems Greencell Tech · Battery recycling
Battery recycling.
A more circular future.
We recover critical mineral rich Black Mass from end-of-life lithium-ion batteries at our facility in Harohalli, Karnataka, and supply it as feedstock to refining partners.

What we do
End-to-end battery recycling capabilities
Black Mass production
Mechanical pre-treatment converts end-of-life battery scrap into high-purity black mass, preserving critical materials.
Nickel · Cobalt · Lithium content
Industrial safety
Inert-gas shredding chambers and dust-capture pipelines for controlled processing.
Inert-gas · Dust-capture
Environment-safe operations
Closed-loop water systems and operations aligned with EPR frameworks.
EPR framework
Downstream feedstock supply
Screened, quality-tested black mass packaged as uniform feedstock for hydrometallurgical refining partners.
Battery-grade feedstock
Our process
From spent cell to Black Mass, in four stages
- 1
Collection & intake
Batteries collected from OEMs, fleet operators and recyclers.
More detail
Each batch is logged and assessed on arrival.
- 2
Safe discharge & dismantling
Cells safely discharged and separated by chemistry type.
More detail
Separation by chemistry enables targeted downstream processing.
- 3
Shredding & black mass recovery
Mechanical shredding under inert atmosphere.
More detail
Yields black mass with minimal contamination.
- 4
Feedstock distribution
Black mass screened, quality-tested and packaged.
More detail
Delivered as uniform feedstock to hydrometallurgical refining partners.
