Abstract

L'invention concerne des toilettes formées à partir d'un matériau imperméable à l'eau et possédant des parois latérales et une partie de fond. Une sortie (5) est associée à la partie de fond, et un filtre sépare cette partie de fond de la sortie (5). Le filtre retient les déchets solides mais laisse passer les déchets liquides par la sortie (5); ces déchets sont ensuite évacués depuis un sac (1) à travers la sortie (5) en cours d'utilisation. De manière générale, les toilettes comprennent un sac (1) formé à partir d'un matériau souple imperméable à l'eau, qui est placé dans un récipient rigide (10).
