Advanced wet mechanical recycling

Recovering Critical Raw Materials from Lithium-Ion Batteries

Ecco Battery and Metal Recycling processes end-of-life lithium-ion batteries using a safe, advanced wet mechanical recycling process.

  • Lower fire risk
  • Very low dust
  • High material recovery

Built for safer recovery

A cleaner route back to critical materials.

We process end-of-life lithium-ion batteries with water at the heart of the shredding and separation process.

This controlled approach reduces dust, fire risk, and thermal runaway while recovering more of the materials needed for future batteries.

Why wet processing

Engineered around safety, recovery, and resource efficiency.

Very Low Dust Emissions

Wet processing keeps dust formation to a minimum throughout shredding and separation.

No Combustion Emissions

Our process is not based on thermal incineration, so it produces no direct combustion emissions.

Reduced Fire & Explosion Risk

Wet processing significantly reduces fire and explosion risk by minimizing dust formation and thermal runaway during shredding.

High Recovery Rates

Advanced separation technology delivers high recovery rates of lithium, nickel, cobalt, manganese, and graphite.

Water Reuse

Process water is treated and reused wherever possible, reducing waste and environmental impact.

Lower Carbon Footprint

Reduced waste generation and a lower carbon footprint compared to primary raw material extraction.

Five controlled stages

From battery feedstock to recovered resources.

Every stage is designed to keep material contained, separate valuable fractions efficiently, and return process water to the system.

1

Wet Shredding

Process: Battery cells or modules enter an industrial shredder under continuous spraying of washing liquid.

Purpose: To prevent sparks, short circuits, and thermal runaway while simultaneously dissolving electrolytes.

2

Washing

Process: The shredded battery fractions undergo intensive washing within the liquid circuit.

Purpose: To completely wash and separate soluble lithium salts and organic solvents from the solid materials.

3

Coarse Material Separation

Process: The total slurry is routed through a specialized separation unit.

Purpose: Coarse fractions such as copper foil, aluminium foil, and plastics are efficiently separated, leaving a liquid stream containing only fine black mass particles.

4

Decanter Centrifuge (Mechanical Dewatering)

Process: The fine slurry from the separation unit is pumped directly into a continuously operating decanter centrifuge.

Purpose: Extreme G-forces separate the valuable black mass from the liquid as a compact cake, while the liquid is recycled back to the shredding and washing steps.

5

Drying

Process: The dewatered black mass cake is fed directly into an industrial dryer via a screw conveyor.

Purpose: Remaining moisture evaporates completely, producing a dry, high-purity powder ready for direct regeneration.

Keep critical materials in circulation.

Recovered minerals can be refined and returned to battery production. That reduces pressure on virgin mining, conserves finite resources, and lowers the environmental impact of future battery supply chains.
