  • Receptacle for secure collection of waste
    Patent number: 9796526
    Abstract: A waste collection receptacle, for example a receptacle in compliance with Drug Enforcement Agency (“DEA”) regulations concerning the disposal of controlled substances, includes a housing and a waste-collection container therein. A chute directs waste deposited through an aperture in the housing into the waste-collection container. A fill sensor monitors the fill level of the waste-collection container. When the waste-collection container reaches a fill threshold, a controller sends a signal that electronically locks the aperture, thereby preventing additional waste from being deposited into the receptacle.
