Honda to Recycle Rare Earth Metals from Hybrid Car Batteries
Honda and Japan Metals & Chemicals will begin extracting rare earth metals from used nickel-metal hydride batteries collected from Honda hybrid cars.
The batteries will be sourced from Honda hybrid cars sold in Japan and around the world.
Starting at the end of this month, Honda says the new operation will be the first in the world 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 stabilisation 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% 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 for a wide range of Honda products. Moreover, 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.
Giving consideration to the recycling of resources used for its products, Honda has long been committed to the 3R (reduce, reuse, recycle) approach. For instance, Honda was the first Japanese automaker to begin sales of recycled parts and to collect/recycle oil filters and replaced bumpers. Honda will continue strengthening its network which links to the reuse and recycling of resources.
