Sustainability impact

Equipment engineered for long-lasting operation and built from recyclable materials, in line with the principles of the circular economy.

Key features

Premium black mass

Thermal removal of PVDF and electrolytes produces purer black mass, better paid by refineries.

More efficient separation

The dry calcined material separates mechanically more cleanly and with higher yield than non-pyrolyzed batteries.

Complete gas treatment

Pyrolysis gases pass through secondary combustion, an alkaline scrubber for HF and activated carbon.

Product description

Advanced thermal processing of waste lithium batteries through controlled pyrolysis, also known as carbonization, removes electrolytes, the PVDF binder and the separator before the mechanical separation stage. The line produces a dry calcined material, free of volatilized organic components, which separates mechanically much more efficiently and cleanly than non-pyrolyzed batteries.…
