Everyone goes to the holodeck to fuck, and apparently they make the lower deckers clean out the biofilters?
Why?? Just dematerialize it on the spot and send it back to the sterilized organic particulate suspension tanks! (TNG Technical Manual p. 91, the tech manuals are cannon deal with it nerds 😎)
Ah, but that very Technical Manual (ch. 12.5) clearly states that solid waste is transported through linear induction utlity conduits - no mention of dematerialization, except in the case of those materials that cannot be recycled by mechanical or chemical means!
