A bucket toilet is a type of latrine where a bucket or other container is used to collect human waste. There are several synonyms for the term "bucket toilet," including pit latrine, dry toilet, composting toilet, and eco-toilet. A pit latrine is a basic form of sanitation that involves digging a hole in the ground and using a bucket or other container to collect waste. A dry toilet is similar to a pit latrine, but uses a system of ventilation to reduce odor and flies. Composting toilets use organic materials like sawdust or straw to break down waste and create compost. Eco-toilets are designed to be environmentally friendly and use little water or electricity.
