@CiaraNi @afewbugs I’m in New York City and we’re now told to put single-use alkaline batteries in the regular trash, with (only) the largest ones taped up to prevent contact. I vaguely recall that’s a recent-ish thing though as that used to not be the case. For non-alkalines there are drop-offs and occasional “disposal events.” Also, you can theoretically bring them to any store that sells them. In theory.
