Storage and sorting system comprising at least - one stack of trays o the stack of trays comprises at least two trays stacked on top of each other o In each tray there are at least two stacked sorting pallets (02, 03,...) for individual storage of objects (A, B, C,...). ▪ Each pallet (02, 03,...) comprises individual storage units of different size. - a mobile transport unit is provided on which the stack of trays is transportable, - a sorting apparatus (100/200/300) is provided, which allows for picking up an individual object A or B or C (...) or a group of individual objects from any of the trays and any of the pallets (02, 03,...) respectively, wherein the sorting apparatus (100/200/300) comprises two or three mechanisms: a. A mechanism that is adapted to lift up the tray(s) from the source tray in which the object(s) (A, B, C,...) is/are located, b. A mechanism that is adapted to lift up any/all pallets (02, 03,...) inside the source tray, from the pallet (03,...) on which the object (A, B, C,...) is located c. A mechanism adapted to pick up and transfer the object (A, B, C,...) from the source pallet to a target tray which is either part of the stack of trays or a separate tray wherein in the case of two mechanisms mechanism "a." and mechanism "b." are the same mechanism and wherein the mechanism a and b are provided as adjacent multiples n with an any natural number of greater or equal to 1 with a single or a number of adjacent mechanism(s) c that is lower than the number of mechanisms a and/or b but is at least 1. - one stack of trays o the stack of trays comprises at least two trays stacked on top of each other o In each tray there are at least two stacked sorting pallets (02, 03,...) for individual storage of objects (A, B, C,...). ▪ Each pallet (02, 03,...) comprises individual storage units of different size. o the stack of trays comprises at least two trays stacked on top of each other o In each tray there are at least two stacked sorting pallets (02, 03,...) for individual storage of objects (A, B, C,...). ▪ Each pallet (02, 03,...) comprises individual storage units of different size. ▪ Each pallet (02, 03,...) comprises individual storage units of different size. - a mobile transport unit is provided on which the stack of trays is transportable, - a sorting apparatus (100/200/300) is provided, which allows for picking up an individual object A or B or C (...) or a group of individual objects from any of the trays and any of the pallets (02, 03,...) respectively, wherein the sorting apparatus (100/200/300) comprises two or three mechanisms: a.
