Cartridge for medical and hospital waste, which defines a tubular body (1), of cylindrical or prismatic configuration, provided with a bottom and divided internally by multiple partitions, which define along the cartridge several chambers or holes, with square shape, to deposit or insert the waste material, characterized in that it comprises: - a flexible sheet defining the tubular body (1) and the base (3) of the cartridge, which is folded flatly in the middle of the hard cardboard base (3) and by folding lines (12) of the tubular body, forming a flat easily storable body, said sheet comprising: - side surfaces (11) that when unfolding or separating hollowing out the interior space define the walls of the tubular body (1) of the cartridge; - semi-base paths of hard cardboard (3a, 3b), of configuration according to the perimeter adopted by the tubular body (1) formed, which are joined to the lateral surfaces (11) that will give rise to the body of the cartridge by means of respective flaps ( 31a, 31b) located in the central area of the cartridge in folded position; - two overlapping flaps (4a, 4b) joining the two semi-bases of hard cardboard (3a, 3b) in the middle area of the base and forming in the unfolded position of the cartridge a diametrical partition (4), aligned with the folding lines (12) of the cartridge body, which is slightly tucked under the base of hard cardboard (3), preventing it from deforming or crushing the cartridge once assembled; - several flanges (33), which emerge radially from the two semi-bases of hard cardboard (3a, 3b) and are joined to them by fold lines, which in the formation of the cartridge are folded and positioned perimetrally and outwardly forming together with the partition (4) a support of the base (3); - a lattice (2) of sheets of cardboard, which is placed folded inside the tubular body (1), which when unfolding the cartridge opens to occupy the entire inner surface thereof.
