Unplanned waste stream diversions are detected through the use of Radio Frequency Identification (RFID) tags. Input bulk material coming into the facility is laced with multiple RFID tags, which are suspended in a colloidal state in the input bulk material. Incoming RFID tags are counted, and then re-counted as they leave the facility, either as part of a known waste material stream or as part of a finished product. If the incoming and outgoing counts differ, then a conclusion is reached that some of the incoming RFID tags are within an unplanned waste stream diversion.
