PORTABLE TOILET OR MOBILE TOILET
A portable toilet or mobile toilet is a toilet that may easily be moved around. They may be toilets that can be brought on site, such as a festival or building site, to quickly provide sanitation services.
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 toilets are chemical toilets, but other types exist as well, such as urine-diversion dehydration toilets, composting toilets, container-based toilets, bucket toilets, freezing toilets and incineration toilets.
