Closing the loop on clean energy
Ohreems Green-Cell Technologies transforms end-of-life lithium-ion batteries into recovered critical metals — sustainably, responsibly, at scale.
What we recover
End-to-end battery recycling solutions
Through advanced hydrometallurgical processes, we extract and purify materials ready for reuse in new battery manufacturing and beyond.
Black Mass
Recovered cathode material containing lithium, nickel, cobalt, and manganese compounds essential for new battery manufacturing.
Li · Ni · Co · MnCritical Minerals
Refined lithium carbonate, cobalt sulfate, and nickel sulfate — battery-grade materials ready for cell manufacturers worldwide.
Battery-grade purityBy-Products
Copper foil, aluminium sheet, and reclaimed plastics recovered during processing — zero-waste outputs repurposed across industries.
Cu · Al · PolymersOur process
From spent cell to refined metal
A closed-loop process designed for maximum yield, minimal emissions, and full chain-of-custody traceability.
Collection & intake
Batteries collected from OEMs, fleet operators, and recyclers. Each batch logged and assessed on arrival.
Safe discharge & dismantling
Cells safely discharged and separated by chemistry type for targeted processing.
Shredding & black mass recovery
Mechanical shredding under inert atmosphere yields black mass with minimal contamination.
Hydrometallurgical refining
Leaching, solvent extraction, and precipitation produce battery-grade mineral outputs.
Why it matters
The case for lithium-ion battery recycling
Demand for critical minerals is accelerating. Recycling is not a trade-off — it is the only viable path to a secure, sustainable supply chain.
Environmental protection
Diverts hazardous materials from landfill. Recovering metals in-loop cuts lifecycle carbon by up to 70% versus virgin mining.
Resource sovereignty
Reduces reliance on geopolitically sensitive mineral sources by creating a domestic, traceable supply of critical materials.
Economic value creation
Recovered materials command commodity pricing. Battery recycling generates skilled employment and reduces raw-material costs industry-wide.
Circular economy
Keeps high-value materials in productive use indefinitely — supporting a fully circular battery supply chain from cell to cell.
