Abstract: A system for sorting materials comprising a sorting apparatus comprising a handling tool and a robotized arm for displacing the handling tool over the materials; and a vacuum apparatus creating a depression and having a tubing extending from a source for the depression to the handling tool where the tubing for the vacuum apparatus ends and where it defines a diameter. The handling tool is adapted to be displaced to a selected item among the materials and perform a contact therewith with the end of the tubing for the vacuum apparatus for either: grabbing the selected item if the selected item is larger than the diameter; or sucking up the selected item if the selected item is smaller than the diameter, wherein sucking up the selected item has the selected item travel under the effect of the vacuum apparatus.
