Each waste classification receptacle is equipped with an integrated scale that detects when debris is thrown. The change in weight activates a sensitive, fully customizable message that slides, moves, or appears on the screen. When users throw away their waste, all the weights in all the containers are recorded and the screens provide an immediate response.
