Eco-toilet is a dry toilet that uses a predominantly aerobic processing system that treats excreta, typically with no water or small volumes of flush water, via composting or managed aerobic decomposition. Composting toilets may be used as an alternative to flush toilets in situations where there is no suitable water supply or waste treatment facility available or to capture nutrients in human excreta as humane.
A good toilet, together with a safe reliable water supply and the practice of good personal hygiene, can do much to improve children health and learning environments.
