Desiccation would have a solid chance to work in very DRY climate with the use of a near constant fan for one person....? Two peoples solid wast likely would need summer temps also.
High humidity areas would be considerably less likely. (Judging from clothes hanging on a line in both climates)
My point is where and when you spend your time would likely be a significant factor if your planning desiccation of your "solid" waste....
And that could, maybe should, enter into the decision of which type of wast handling you choose...?
