Honda to recycle hybrid car batteries

Honda Motor Co., Ltd. and the Japan Metals & Chemicals Co., Ltd. have established a process to extract rare earth metals from various used parts in Honda products, in an actual mass-production process at a recycling plant, not an experimental process. Honda will pursue the recycling of precious resources by utilizing the newly established process for the recycling of rare earth metals.

As part of this effort, Honda and Japan Metals & Chemicals will begin extracting rare earth metals from used nickel-metal hydride batteries collected from Honda hybrid vehicles at Honda dealers. The new operation will be the first to extract rare earth metals as part of a mass-production process at a recycling plant.

Honda had been applying a heat treatment to used nickel-metal hydride batteries and recycling nickel-containing scrap as a raw material of stainless steel. However, the successful stabilization of the extraction process at the plant of Japan Metals & Chemicals Co., Ltd. made possible the extraction of rare earth metals in a mass-production process with purity as high as that of newly mined and refined metals.

The newly established process enables the extraction of as much as above 80 percent of rare earth metals contained in used nickel-metal hydride batteries. Honda will strive to reuse extracted rare earth metals not only for nickel-metal hydride batteries, but also to a wide range of Honda products.

Honda will further expand the recycling of rare earth metals in the future as the newly established process enables the extraction of rare earth metals from a variety of used parts in addition to nickel-metal hydride batteries.
