A system includes a trash box, a data acquiring device, a computer of a facility, a mobile, and a management server. The trash box is placed in a space facing a road for the mobile in the facility. The data acquiring device acquires collection status data of a trash in the trash box. The management server or the computer of the facility determines whether a collection of the trash box is required based on comparing a judgment element calculated by using a collection status data with a judgment threshold. The management server transmits a collection order to the mobile if it is determined that the collection of trash box is required. The mobile comprises an automatic collection device. The automatic collection device performs an automated replenishment control of the trash box if the mobile receives the collection order.
