The Duesenfeld Advantage

The Duesenfeld Process

The safest, most eco-friendly, highest-recovery battery recycling technology in the world.

A four-step process:

No furnaces required — No special permits — Zero hazardous waste — 90%+ material recovery — Battery-grade output, ready for reuse

1: Deep Discharge

Materials are processed under an inert gas blanket, producing zero combustion and zero hazardous emissions.

2: Manual Disassembly

Residual energy is safely recovered, eliminating fire and explosion risk before disassembly even begins.

3: Shredding & Sorting

Precise separation of heavy metals and plastics for maximum material purity.

4: Chemical Extraction

Battery-grade rare earth material recovery at 90%+ efficiency.
