Technical sheets: "Otji" toilet

Peter Arndt

EcoSouth has published various technical sheets about EcoTechnologies and EcoMaterials and with each update will introduce one into the website. The first focuses upon dry toilets, a theme that drew much attention during EcoMaterials 2005 when Peter Arndt presented his experiences. Because of the scarcity of water in the extremely dry environment of Namibia, the Clay House Project in Otjiwarongo has experimented with advanced dry toilet designs that are found on the market. It has simplified them to the point that they are not only affordable, but also can be easily cleaned.

Tips

CP40 is a hydraulic binder produced from the mixture of a material known as Pozzolana and finely ground Calcium Hydrate. This binder is of low mechanical strength and its setting speed is a little bit slower than Portland Cement. Because of this, it can be considered as a cement for masonry applications.
