context_page_description: A portable or mobile toilet is any type of toilet that can be moved around, some by one person, some by mechanical equipment. Most types do not require any pre-existing services, such as sewerage disposal, but are completely self-contained.
  They can be used in a variety of situations, for example in urban slums of developing countries, at festivals, for camping, or on boats. One well-known type of portable toilet is a chemical toilet but other types also exist, such as urine-diversion dehydration toilets, composting toilets, container-based toilets, bucket toilets, freezing toilets and incineration toilets.
  A portable toilet is not connected to a hole in the ground, nor to a septic tank, nor is it plumbed into a municipal system leading to a sewage treatment plant; it can, by definition, be picked up and moved. Some portable toilets can be carried by one person, as in the main image, whereas others need heavy lifting equipment such as a truck and crane.
context_section_description: A chemical toilet collects human excreta in a holding tank and uses chemicals to minimize the odors. These chemicals may either mask the odor or contain biocides that hinder odor-causing bacteria from multiplying, keeping the smell to a minimum. Chemical toilets include those on plane and trains (although many of these are now vacuum toilets), as well as much simpler ones.
