Chemical toilet

A chemical toilet collects human excreta in a holding tank and uses chemicals to minimize odors. These toilets are usually, but not always, self-contained and movable. A chemical toilet is structured around a relatively small tank, which needs to be emptied frequently. It is not connected to a hole in the ground (like a pit latrine), nor to a septic tank, nor is it plumbed into a municipal system leading to a sewage treatment plant. When the tank is emptied, the contents are usually pumped into a sanitary sewer or directly to a treatment plant.

Many chemical toilets use a blue dye in the bowl water. In the past, disinfection was generally carried out by mixing formaldehyde, bleach, or similar chemicals with the toilet water when flushed. Modern formulations are nitrate-based and work biologically. Since formaldehyde is very irritating to the eyes, ears, skin, nose, and throat, it is being replaced by other proprietary blends such as glutaraldehyde and quaternary ammonium compounds, with non-staining dyes and nature-identical perfume oils. Additionally, enzyme hybrids are sometimes used.
