Metal Recycling Project from Ni-H Batteries for Hybrid Electric Vehicles and Slag
JOGMEC is working to make hybrid electric vehicles (HEV) even more environmentally friendly by developing methods to efficiently recycle the metals used in their batteries.
In a project supported by Japan's Ministry of Economy, Trade and Industry (METI), JOGMEC is researching nonferrous metal recycling technologies and ways to reduce energy consumption in using nonferrous metal facilities and technologies for recycling HEVs. Core themes include technology for solidifying automobile shredder residue (ASR), technology for the recovery of valuable metals from waste nickel hydrogen (Ni-H) batteries and ASR, and improving the quality of the resulting slag.
Recovering Metals from Hybrid Vehicle Batteries
JOGMEC's Metals Mining Technology Group has been creating technology to efficiently recover nickel, cobalt and misch metal, which is a mixture of rare earth metals such as lanthanum and cerium, from waste Ni-H hydride batteries used for HEVs, and to refine the recovered metals for reuse in new batteries.

Technology for Extracting Base Metals from Slag
JOGMEC has developed technology for the complex process of recovering valuable base metals from the slag created in recycling items such as autos and home appliances while simultaneously removing harmful elements and impurities. JOGMEC has also developed technology to clean slag generated when automobile shredder residue (ASR) is treated in copper flash furnaces to recover copper, lead and zinc contained in slag.
