Back when... in 1970's, I owned a then like new 31' "Holiday Rambler Presidential" travel trailer. She had all the options; a self contained beaut! Built like a BSH - pun intended toward this thread's ongoing discussion. LOL
Anyway... one feature was its tow vehicle “black tank” reduction system, via exhaust: In that, during 100 miles highway travel the entire black tank (when full) could evidently be emptied and burned by the tow vehicle’s exhaust heat. I don’t recall exactly what turned me away from using that system after careful review of its instructions, however, I never used that feature. Simply seemed more sanitary to utilize dump stations where sewage can be sent to treatment locations or placed into huge septic tank systems with liquefied distribution into expansive leach fields.
That being said... On land, septic tank fed leach field systems properly sized/constructed and often fed with correct bacteria are one of the one of the most efficient and “green” (i.e. naturally clean) manners of treating human waste... bar none!
