The problem is that scrapyard is a victim of intensive wiki fiddling and conning the iD developers in to dropping the tag.
amenity=scrapyard was in common use https://taginfo.openstreetmap.org/search?q=scrapyard#values prior to the above (it used to have far more use than now) and would seem to be the obvious choice for a facility that provides such services publicly, contrary to simply tagging the landuse. So my solution would be to add a node with the tag in the appropriate place and adding the business tags to that.
