Which of the following is NOT a method for disposing of human waste?

The correct choice identifies composting toilets, which are designed to treat and recycle human waste by composting it rather than disposing of it in a traditional sense. Unlike the other methods listed, which focus on the immediate disposal of waste to prevent contamination and disease spread, composting toilets process waste to create a usable end product, such as compost. This method involves aerobic decomposition and requires more management and oversight compared to simple disposal methods.

In contrast, disposal methods like deep pits, saddle trenches, and pail latrines are all focused on the immediate containment and management of human waste to prevent health hazards. These methods are critical in military settings, where sanitation is essential for maintaining troop health and preventing the spread of disease. They involve straightforward techniques for safely isolating waste from living areas and ideally allow for easy access and monitoring.
