Key drivers for battery recycling industry

Battery black mass recycling is becoming increasingly important as a supplement to virgin material supply, as well as a way to reduce the carbon footprint of the battery supply chain.

With the increasing demand for zero emission vehicles and the need to create a circular economy, the battery recycling industry is inevitably set to see new and prosperous growth opportunities.

Introducing Battery Black Mass Recycling Process

The Battery Black Mass Recycling Process treats batteries after mechanical separation and optional thermal treatment for the recovery of nickel, cobalt and lithium, as well as optionally manganese and copper.

The overall objective is to close the loop on battery raw materials through hydrometallurgical processing. Our decades of process know-how and equipment design enable us to create efficient and responsible methods for recycling and reusing minerals from decommissioned batteries.
