ECOSAN

ECOSAN or ECOLOGICAL SANITATION is an approach to sanitation that saves water, does not pollute, and returns the nutrients in human excreta to the soil.

It is called ecological because it seeks to reconnect the natural cycle of food-waste-food which has been broken by conventional sanitation. Plants give nutrition to herbivores, who serve as a food for the animals higher in the food chain.

When animals defecate, the unused nutrients are transferred back to soil for the use of plant.
