We take charge of the recovery of your EV batteries.

Innovation to make the energy transition truly sustainable

Developed by our experienced process engineers and chemists, our strategic materials extraction and purification technologies combine the novel use of existing processes with new operations designed for optimal results.

The outputs are battery-grade strategic materials that can be used by cell and battery manufacturers to produce new lithium-ion batteries.

Step 1: Mechanical extraction.
Battery packs are shredded to produce our signature hydromet-ready critical minerals concentrate, ie Black Mass. Our technology enables us to recuperate MORE THAN 98% of the minerals concentrate!
Step 2: Hydrometallurgy.
The critical minerals concentrate is processed through our patented hydrometallurgy technology to recover battery-grade lithium, cobalt, and nickel as well as graphite and manganese. We recover MORE THAN 95% of critical minerals of the batteries! The purity level of our strategic materials is unmatched!
