Establishment of circular economy system for metal resources
Recycled lead is made by extracting metallic lead from waste lead acid batteries through collection and recycling processes. This recycled lead is used by lead-acid battery manufacturers as raw materials for manufacturing automotive batteries.
DS DANSUK is building a global supply chain for waste lead-acid batteries and contributing to the creation of economic values such as environmental protection and cost reduction while practicing resource circulation through recycling.
Additionally, we are securing competitiveness within the battery recycling industry by enhancing product reliability through registration of our recycled lead brand on London Metal Exchange (LME).
The purity of recycled lead is over 99.97% and has the same characteristics as primary lead.

Basic Materials for LIB Recycling
Black mass is extracted from physically crushed waste lithium ion batteries (LIBs) and contains valuable metals such as lithium, cobalt, nickel, and manganese. DS DANSUK has a process to extract black mass, copper, and aluminum by recycling waste resources such as waste batteries and scraps generated during the process by discharging, crushing, grinding, and screening, and can produce about 5,000 tons of black mass per year.
Black mass contains metals at levels of 20-45% Ni, 5-15% Co, and 3-7% Li.
Forming a closed loop through the recovery of valuable metals in waste batteries
Used by LIB material (precursor, etc.) companies after refining into lithium carbonate, lithium hydroxide, nickel sulfate, and cobalt sulfate
