Landfill isn't so bad though. Segregating identical waste into one place is a fine approach, because once it becomes possible to recover it, now you know where it is. Think of it as a mine. (It's a problem if it leaks into the groundwater of course.) But lithium is not at all rare so it's not going to be hard to make more batteries.
