Abstract: The invention relates to a bin for storing a volume of waste that can be reduced by compaction, said bin comprising means which reduce the pressure exerted in the volume of the bin, under the effect of a vacuum, and ensure that the waste is compacted. The inventive bin is characterised in that said means are embodied in the form of a tight deformable enclosure (1) in which the waste is collected, optionally contained in a disposable bag, and said tight deformable enclosure comprises at least one lateral wall consisting of an assembly of rigid plates or segments (2) which are articulated in relation to each other in such a way as to form a deformable apron that subjects the waste to a compression force between the lateral deformable apron wall and the opposite wall, under the effect of the vacuum being exerted in the enclosure, one of the sides of said enclosure being open for introducing waste, and provided with a tight cover (6).
