Recycling

Eco-friendly Spent Electrode Recycling Technology
Kumkang Engineering researches and develops eco-friendly recycling technologies for spent battery electrodes. Through efficient recovery and recycling of valuable metals, we contribute to a sustainable circular economy while minimizing environmental impact. We continuously advance our technologies across the entire recycling process—from pretreatment to resource recovery and reuse—to achieve both environmental and economic value.

Need for Recycling
  • Securing high-purity raw materials at low energy cost and with low carbon emissions compared to ore-based materials through recycling
  • Compared with ore, recycling enables reductions of CO2 74%, NOx 92%, SOx 92%, and water use 97%
  • Cathode materials accounting for 30~40% of lithium secondary battery material costs — stable supply and cost reduction
