Abstract:

A brief look around the globe shows that most countries are facing sanitary problems, especially in the expanding cities in the Southern Hemisphere. Governments and municipal councils are trying hard to improve sanitation conditions within the mind set of piped systems. There is a need to know what is being done in other countries in order to enlarge the policy options. Among these are the ones recirculating water and nutrients. This article focuses on excreta disposal systems which use little or no water, and various ways to use the end products of faeces and urine. Doing away with our urine blindness will pave the way to discover new possibilities which will save scarce resources in the future.
