Hygienic Water-Free Toilet

This project aims to redefine the receiving material for human waste from water to granular material, thereby completely bypassing the need for water in this process. The project aims to redesign the conventional toilet to use a bed of granular that will ensure that there is no fecal staining of the system, fecal matter is cut-off from vectors, does not contaminate surface waters and that the user is always presented with a fresh, clean and dry surface.
