Humanure Kenya

Composting toilets are eco-friendly sanitation systems that use natural processes, primarily decomposition and evaporation to recycle human waste into a nutrient-rich fertilizer. These toilets do not rely on water, plumbing or sewage systems, making them ideal for off-grid living or areas with limited access to sanitation infrastructure. In a typical composting toilet setup, human waste comprising urine, feces and a dry organic cover material such as sawdust is collected in a container. After each use, the waste is covered with a dry material (like sawdust, dry leaves, or straw) which helps absorb moisture, control odour and promote aerobic decomposition. 

The collected waste is then placed in a composting area, usually in a shaded outdoor bin, where it undergoes further breakdown through microbial activity and evaporation. After a period of time the waste is transformed into a safe, earthy-smelling compost also known as humanure. This natural fertilizer is used in non-edible plants, trees or in landscaping, helping to enrich soil health while closing the nutrient cycle.
