An UDDT seems to be the most environmentally friendly alternative, but for some contexts, a composting toilet might seem preferable (like rentals, or camping sites where people don't always remember to use the toilets correctly).

What are the disadvantages of using a composting toilet in terms of:

  • Waste generation: does the composting chamber generates black water? gases?
  • Odour: does the presence of moisture and greater humidity contribute to the generation of unpleasant odours?
  • Maintainability: how often do you have to take care of the compost?

For what I have gathered, a double chamber UDDT needs to be maintained once a year, does not generates waste and, since it's dry, it doesn't smell bad. Can all these characteristics be achieved by some composting toilet design?

This is a 'mouldering toilet' It composts, but slowly.

Downsides:

Bulky: You need room to move a drum in and out under the seat.

Needs to be kept warm to work. (True of most non sewage toilets)

Upsides: Simple, stink free.
