   Les extractions, et les remplissages qui suivent   immédiatement,   peu- vent avoir lieu par exemple tous les 4, 5 ou 6 jours afin, d'une part, de ne pas ouvrir trop souvent la cellule et d'autre part, de bénéficier au maximum des vides de tassement. La remplissage peut toutefois avoir lieu journelle- ment en cas de besoin. Ces extractions et remplissages peuvent être effectués encore plus rapidement si on ne désire par exemple qu'aseptiser les ordures afin de permettre leur   .manipulation   sans danger ou en vue de les   laisser   fer- .mentor   l'air   libre.

 fermentation of household refuse, materials and various waste, which is charac- terized in that in the full cell, one or more separating elements are introduced at a determined level, covering a plane of horizontal section, preferably in the form of a grill, the only fermented materials located below these elements are withdrawn, then the aforementioned elements are removed and, the load previously located above them, being dropped to the bottom of the cell , performs the filling thereof;

   the capacity between said elements and the bottom of the cell being substantially equal to the volume which will occupy, after fermentation, the materials discharged during this loading.



   2 - A fermentation cell for the implementation of the process according to claim 1, characterized in that opposite a lateral opening for the introduction of the aforementioned elements, are arranged slides, for the support and sliding of these elements , and means are provided for hermetically sealing this opening.



     @ - A fermentation cell according to claim 2, charac- terized in that the bottom of the cell, on which the materials are based, consists of an inclined grid, opposite which the cell has a lateral discharge opening provided with a. opening retaining grid and watertight closure means.



   4 - A fermentation cell according to claim 2, characterized in that the mass of materials being treated is continuously crossed from the bottom upwards in the ventilation air.
