When making complex factories it would be nice to have a keyword that functions like a trashcan. My keyword suggestions are "void" or "trash"

output item:: to void
output fluid:: to trash

productivebees example

when using the @productivebees mod I often have an excess of wax. It would be convenient to just have to write

every 20 ticks do
    input from centrifuges
    output wax to void
    output to storage_system
end

Thanks for the suggestion!
Unfortunately, I think that this is outside the scope of what I want the mod to do at this time.
It's easy enough to use a trash can from another mod or make one yourself using vanilla mechanics and labelling it "trash" or "void" such that your exact example would work.
