We already have tens, possibly hundreds of millions of batteries disposed of every few years. They're those nasty lead-acid ones that every conventional car comes with. There are already laws and recycling rules in place so those batteries are dealt with properly. The batteries in hybrids are no exception. The manufacturers will work with the government to see that they are handled safely and properly. One thing that they have going for them is that NiMH is far, FAR safer than lead-acid batteries. See short snippit below:lethostigma said:I found myself a bit uneasy when asked about the potential impacts on the environment of creating and disposing large batteries for hybrids. Does anyone have any thoughts about this topic? If hybrid sales exploded and we had millions of batteries to deal with, what would the impact be? Can they be recycled or are they not really a concern if contained in a suitable landfill? Does anyone know where Honda America stands on the issue? What has happened to the few batteries that have already died?
"NiMH batteries are 100% recyclable, and contain no toxic materials (lead, cadmium, or lithium ) that can be hazardous to the environment. Actually NiMH batteries are the only rechargeable battery that can be legally disposed of in a landfill. There are also disposal facilities in most major areas that will also dispose of your batteries for you."
