What “other types”? Why not simply =waste_basket + Key:waste_basket - OpenStreetMap Wiki (which should otherwise use bin=yes ) =amnesty+ waste=knives . The latter-most is what 3 are already using, 2 of them clear.
name=Knife Amnesty BinNode: Knife Amnesty Bin (11808359645) | OpenStreetMapname=Bin a BladeNode: Bin a Blade (10221297023) | OpenStreetMap- Unnamed Node: 8439701715 | OpenStreetMap
Another unclear misspelling =knifes Node: 11932629568 | OpenStreetMap
Or as a compromise, =amnesty_bin + waste=knives to at least reuse waste= . There can be waste= =drugs etc for them. There’s no need reinvent the list of waste= in amnesty_bin= .
waste_basket= / amnesty_bin= can instead be used for the purpose of =sports etc, if they are permanent. They may not be located inside the area of that facility, lacking spatial relationship to be identified.
