An automated receptacle handling system comprising: - an automated receptacle handling device comprising a receptive space for receiving a waste bin carrier , - a waste bin carrier configured to be introduced into the receptive space of the automated receptacle handling device , and - a locking mechanism movably attached to the waste bin carrier for releasably securing at least one waste bin to the waste bin carrier , wherein: - the waste bin carrier comprises a frame and a base attached to the frame (110, the base being configured to receive thereon the at least one waste bin , - the locking mechanism is movably attached to the frame , - the locking mechanism is configured to be manipulated between a deployed state, in which the locking mechanism engages the at least one waste bin , and a released state, in which the locking mechanism is disengaged from the at least one waste bin , characterized in that : - the locking mechanism comprises: ∘ a pusher guide extending in a first horizontal Cartesian dimension (X) for lateral engagement with the at least one waste bin , and ∘ at least one articulated arm connecting the pusher guide to the frame of the waste bin carrier so as to allow movement of the pusher guide in respect to the frame between the deployed state and the released state, and in that - in the released state the pusher guide is proximal to the frame and in the deployed state the pusher guide is distanced from the frame in a second horizontal Cartesian dimension (Z). - an automated receptacle handling device comprising a receptive space for receiving a waste bin carrier , - a waste bin carrier configured to be introduced into the receptive space of the automated receptacle handling device , and - a locking mechanism movably attached to the waste bin carrier for releasably securing at least one waste bin to the waste bin carrier , wherein: - the waste bin carrier comprises a frame and a base attached to the frame (110, the base being configured to receive thereon the at least one waste bin , - the locking mechanism is movably attached to the frame , - the locking mechanism is configured to be manipulated between a deployed state, in which the locking mechanism engages the at least one waste bin , and a released state, in which the locking mechanism is disengaged from the at least one waste bin , - the waste bin carrier comprises a frame and a base attached to the frame (110, the base being configured to receive thereon the at least one waste bin , - the locking mechanism is movably attached to the frame , - the locking mechanism is configured to be manipulated between a deployed state, in which the locking mechanism engages the at least one waste bin , and a released state, in which the locking mechanism is disengaged from the at least one waste bin , - the locking mechanism comprises: ∘ a pusher guide extending in a first horizontal Cartesian dimension (X) for lateral engagement with the at least one waste bin , and ∘ at least one articulated arm connecting the pusher guide to the frame of the waste bin carrier so as to allow movement of the pusher guide in respect to the frame between the deployed state and the released state, and in that ∘ a pusher guide extending in a first horizontal Cartesian dimension (X) for lateral engagement with the at least one waste bin , and ∘ at least one articulated arm connecting the pusher guide to the frame of the waste bin carrier so as to allow movement of the pusher guide in respect to the frame between the deployed state and the released state, and in that - in the released state the pusher guide is proximal to the frame and in the deployed state the pusher guide is distanced from the frame in a second horizontal Cartesian dimension (Z). <EOS>
