so I looked at the wikipedia definition of building [1], and their
definition of non-buildings [2]
At this moment I think that digester/bioreactor belongs to the non-
building structures, as they list "Structures designed to support,
contain or convey liquid or gaseous matter, "

When you look at [3] the subsection of agricultural buildings, you see
greenhouse listed.

I don't know whether we want to follow the wikipedia definition or
not, but it might help to decide where we have to place future tags.
