  • Waste bin and method of sorting waste paper products from other types of waste in a waste bin
    Patent number: 11273977
    Abstract: A waste bin comprises a sorting space for sorting waste paper products from other types of waste, a movable separation element comprising a plurality of openings, a physical property sensing mechanism for detecting a physical property of waste received in the sorting space, a removal element for moving waste from the sorting space to a waste paper product compartment, and a control for controlling the movable separation element and the removal element. The movable separation element is configured to move upon the application of an external force exceeding a threshold value. The control is configured to operate the removal element or the movable separation element, based on a detection result of the physical property sensing mechanism. Further, a method of sorting waste paper products from other types of waste in such a waste bin is provided.
