Well, I had about a quarter ton of nicads to dispose of recently, and dealt with all the problems your describing,mind you I'm not that big of a environmental alarmist, though I'm adamantly opposed to dumping in fields and streams, I've seen and suffered the consequences of that kind of pollution, but when I'm put between a rock and and a pile of trash, I'm not above using dumpsters and landfills
All that said I dropped my nicad nightmare at my local low class shreddable yard, At least I know they're not sitting around carroding in a residential neighborhood, steel recycling is about all they're good for,
chemically, it's just a potassium hydroxide electrolyte, caustic, corrosive, not good for skin, leaves chemical burns, but it's water soluble, and should be simple to neutralize with simple acids,
If you wanted to be certain that nobody could be injured by any leaking cells, I'm sure you could find a way to safely neutralize the strong base before dropping the (then chemically inert) metal bodies in the shred yard
