    You mean a one step? Like highway= x ?

    To do that I'd think a new supper key   waste=   at the top level!
    And maybe that is what it needs! If there are enough different
    kinds then why not?
    waste=rubbish_bin
    waste=skip_bin
    waste=dump_point
    waste=chemical_toilet
    waste=dog_excrement
    waste=sharps
    waste=cigarettes
    waste=excrement

What does it take to justify a top level tag?

I think he means that if we use a top level amenity tag like amenity=waste_disposal we are forced to make another whole set of sub keys to describe the waste being disposed of. At least that's where my criticism comes from. If however we can agree on a tag of amenity=dump_point and define it as "a facility where one can dump or discharge the waste tanks of an RV or recreational boat" it can be understood and rendered by evaluating only that single tag.

Whether the waste being dumped is from a "chemical toilet" or from a plastic bag on a "porta-potty" or "cassette" then becomes irrelevant. The facility will handle it.

This new top level tag might make the approval process easier too. Standing alone as it would, it nicely separates garbage and trash, or recyclables, from sewage and doesn't require any other potentially lengthy approvals for new subkeys.
The present sub tag already exists and is in use .. for oil, cigarettes, grey_water, drugs, dog_excrement, etc .. so they still have to be evaluated for a true render of the facility. If what is required is a one tag entry for each waste type then amenity= will be over loaded eg

amenity=waste_dog_excrement
amenity=waste_cigarettes
amenity=waste_sharps

Note the inclusion of waste in the name .. so people don't think that they are places that sell the stuff! :)

about 8 + around 28! if you include waste recycling...
and I think it then needs to be a top level tag .. like shop=, tourism=. sport= etc. as there are too many of them .. and that would be opposed as it is a lot of work to change the present data and a lot of work to change the renders... at least another category of amenity ... presently

Add '2.8 Waste'? I don't know.. just pointing out the possible future problems?
