Incinerating
There are incinerating toilets that have a small profile. They can replace RV or Marine toilets. Most use propane gas and 12 volt D.C. Not as sustainable as a composting toilet, but if you are in a nomad living situation, it may be better. The ash left behind is considered sterile and can be composted or used directly in the garden. A drawback is the need to use disposable products for each use. There may be DIY alternatives that can be used as a replacement.
