wherein the protrusions provide an axis and the entirety of the container is configured to be rotably connected to the axis so as to place the waste system (1, 101, 201) into an open or closed state; wherein the open state is configured to provide access to the upper opening of the cavity; wherein the container is configured to be detachable from the outer casing by lifting the container via the first handle (25, 125, 225) when the waste system (1, 101, 201) is in the open state; wherein the axis is located near the front side (3, 103, 203) of the container, such that a longitudinal centre line of the axis is at a distance d_a1 from the front side (3, 103, 203) of the container, wherein the distance d_a1 is measured perpendicular to and from the front side (3, 103, 203) of the container to the longitudinal centre line of the axis, and the distance d_a1 is between 1% and 15% of the distance d_a2, wherein the distance d_a2 is measured perpendicular to and from the front side (3, 103, 203) of the container to the back side (15, 115) of the casing; and wherein the outer casing further comprises a bottom side (9, 109, 209) and wherein the longitudinal centre line of the axis is at a distance d_b1 from the bottom side (9, 109, 209) of the casing, wherein the distance d_b1 is measured perpendicular to and from the bottom side (9, 109, 209) of the casing to the longitudinal centre line of the axis, and the distance d_b1 is between 90% and 110% of the distance d_b2, wherein the distance d_b2 is measured perpendicular to and from the back side (15, 115) of the casing to the longitudinal centre line of the axis. an outer casing comprising at least a back side (15, 115), two opposing sides (5, 105, 205), and a top side (7, 107, 207), wherein the outer casing has a first longitudinal centre plane extending parallel to the two opposing sides (5, 105, 205), and wherein each of the two opposing sides (5, 105, 205) comprises at least one protrusion, wherein the at least one protrusion are at least directed inwards towards the first longitudinal centre plane; and a container enclosing a cavity (29, 229) for collecting a garbage to be sorted, wherein the container comprises an upper opening for accessing the cavity, wherein a front side (3, 103, 203) of the container provide a front side of the outer casing enclosed by at least the two opposing sides (5, 105, 205) and the top side (7, 107, 207) of the outer casing, and wherein the container comprises at least two parts forming a first handle (25, 125, 225) located at the upper opening of the cavity; wherein the protrusions provide an axis and the entirety of the container is configured to be rotably connected to the axis so as to place the waste system (1, 101, 201) into an open or closed state; wherein the open state is configured to provide access to the upper opening of the cavity; wherein the container is configured to be detachable from the outer casing by lifting the container via the first handle (25, 125, 225) when the waste system (1, 101, 201) is in the open state; wherein the axis is located near the front side (3, 103, 203) of the container, such that a longitudinal centre line of the axis is at a distance d_a1 from the front side (3, 103, 203) of the container, wherein the distance d_a1 is measured perpendicular to and from the front side (3, 103, 203) of the container to the longitudinal centre line of the axis, and the distance d_a1 is between 1% and 15% of the distance d_a2, wherein the distance d_a2 is measured perpendicular to and from the front side (3, 103, 203) of the container to the back side (15, 115) of the casing; and wherein the outer casing further comprises a bottom side (9, 109, 209) and wherein the longitudinal centre line of the axis is at a distance d_b1 from the bottom side (9, 109, 209) of the casing, wherein the distance d_b1 is measured perpendicular to and from the bottom side (9, 109, 209) of the casing to the longitudinal centre line of the axis, and the distance d_b1 is between 90% and 110% of the distance d_b2, wherein the distance d_b2 is measured perpendicular to and from the back side (15, 115) of the casing to the longitudinal centre line of the axis.
