Re: Nix the Sack Lunch & Portapotty

*Waste issues/technology.
Teixeira's plan hinges on patented technology developed by the university called Sequential Batch Anaerobic Composting (SEBAC) that is currently used in landfills. That system turns waste into compost by cycling material among different containers.
At least the article pitches for a 1-1/2 year on-Mars mission. 
Discusses use of leftovers as well.

P.S.: I did check the most recent threads in this folder to see if this article's been posted already. I don't see that it has and Search on this board is still bonkers.
::EDIT::
The SEBAC II system would compost human waste, inedible food material such as plant stems and roots, and paper used for things like moist toilettes used by the crew in the place of baths or showers.
No bubble baths en route?? I'll have to reconsider this... :?

Re: Nix the Sack Lunch & Portapotty
You ever hear tell of a science fiction story, how a colony was in unrest because the guy incharge of waste disposal wasnt doing his job...Earth gov sends an officer out to investigate only to find that the reason he was refusing to push the button that processed waste was every one victimised him and austracised him for being the guy who "handles the shit". Basicly the rest of the colony were a bunch of snobs...So the Earth official (thinking this has gone far enough) pushes the button only to be treated with the same level of contempt as the last guy.

Wow what a bunch of loser. Next time let them handle their own shit.

Proping up the food supply of a Mars colony from Earth. One year's food is going to cost 20 billion (as much as it cost to send the colonist).

Re: Nix the Sack Lunch & Portapotty
But without the portopotty, how are crews going to play the age old joke of tipping over the portopotty while a fellow crew member uses the portopotty?
Morale is vital.

Re: Nix the Sack Lunch & Portapotty
Far worse if the toilet is its own building way off in the distance. A Toilet with an airlock...
Teixeira says the spaceship would probably carry enough food in reusable packages to sustain the crew during the trip to Mars. During a portion of that time, crews would collect the processed waste for use as compost upon arrival and established a greenhouse to grow foods.
