Auto manufacturer Honda Motors Co. Ltd., Tokyo, has announced plans to start reusing the rare earth metals that can be extracted from used nickel-metal hydride batteries by the end of 2012. Since April 2012 Honda has been extracting the metals in cooperation with Japan Metals & Chemical Co. Ltd.
According to a news release issued by Honda, the company says it will pursue reusing the extracted rare earth metals in new nickel-metal hydride batteries and for use in a range of components.
Honda also says it is looking at ways to recover residual voltage from the used nickel-metal hydride batteries so it can be used as regenerative voltage during the disassembly process.
The press release also indicates Honda is studying ways to recycle rare earth metals extracted from used parts such as hybrid motors and lithium-ion batteries.
