Honda's quest for a clean transportation system does not stop at tailpipe emissions, but includes a broad spectrum of sustainability measures including water use reduction, elimination of waste going to landfills, and recycling efforts including extraction of rare earth metals from critical parts.

In order to address climate change and energy issues, Honda has focused for years on reducing CO2 emissions, other greenhouse gas reduction, reduction on the "waste" output created by the company, and recycling materials in Honda's products. An example is the plan announced two months ago to recycle rare earth metals from Nickel-Metal-Hydride batteries in the company's hybrid cars.
Honda Automotive released, yesterday, the Honda Environmental Annual Report 2012 summarizing results of the company's environmental initiatives.

A leading item, which warranted its own press release, is Honda's plan to recycle rare earth metals. Honda reiterated the plan to start, by the end of this year, recycling nickel-metal-hydride car batteries to extract the rare earth metals in those batteries. The company is also striving for, and researching, methods to extract similar rare earth metals from the company's other products, including from lithium ion batteries and the magnets in high powered electric motors.

So-called rare earth metals have this name because of the relative scarcity of mineral deposits with a high enough concentration to be worth mining. They are widely used in electronic gizmos, and in electric vehicles are highly prized for the high power magnets used in some electric motor designs. There is a geopolitical concern stemming from China's success at cornering the market for supplying rare earth metals, largely because Chinese suppliers have undercut all others. There is a concern in many quarters about trading a dependence on fossil oil from foreign countries who aren't friendly to the west, for a dependence on rare earth metals from another foreign country who isn't entirely friendly to the west.

While many companies are looking to restart rare earth metal production outside of China, efforts to recycle these metals should be part of the solution. The paradigm of "use once and throw away" dooms civilization to eventual demise because of the ever expanding amount of land devoted to landfills, and the inevitable "we'll run out of ___fill in the blank___" if nothing is ever recycled.

Honda's recycling program extends beyond rare earth metals to include items such as bumpers, and used oil filters. Honda intends to continue expanding efforts to Reduce, Reuse and Recycle throughout the company. The company has an ASR (Automotive Shredder Residue) Recyling goal of over 70%, and is achieving a 93% recycling rate. In Motorcycles the goal is to reach an effective recycling rate of 95% by 2015, and that rate stands currently at 87.7%.
