Human waste is about 90% water, which means that a primary function of a composting toilet is evaporation. Electric models include a fan that is constantly moving air through the toilet to accelerate the drying out. Bulking material and microbes are added to break down the remaining substance.
Factors to consider: Size and footprint, Energy requirements, Clean out process, and Odor elimination. Compost toilets are 100% less disgusting than dumping black water from a septic tank. Plus, it requires zero fresh water.
PROS: They reduce contact with your waste. They don’t require any special plumbing. Since your composting toilet doesn’t use water to flush away your waste, it doesn’t need a water supply, and it doesn’t need a drain. That actually represents significant cost savings on your plumbing setup. They are environmentally awesome! Microorganisms break down your waste and turn it back into SOIL.
CONS: Can be more expensive at purchase, though very economical long-term.

PROS: Incinerating toilets are waterless and don’t need as much attention as composting. Nothing but sterile ash remains and can be thrown away in the trash.
CONS:they are very expensive, use A LOT of energy - too much to be powered by solar, and or small generators.
PROS: These will most look and operate like the toilets you're used to. Some tiny houses have these, choosing to operate as RVs do.
CONS: like RVs, you must have a septic holding tank and find some place to dump it when it is full.
