In order to encourage residents to separate trash, Nanjing City has introduced “trash banks” that integrate functions such as face recognition, remote monitoring, and trash disposal. The residents first perform face recognition, and then sort out the trash. The system returns points to the user’s account based on the number of recyclables contained in the garbage. Eventually points can be turned into cash.
