A waste management system for associating a collected refuse bin with a corresponding user of that bin. The system comprises a GPS tracker unit on-board a collection vehicle for recording the GPS co-ordinates of each refuse bin during refuse collection therefrom by the collection vehicle. A central server is configured for communication with each of a plurality of collection vehicles so that the GPS co-ordinates of each refuse bin collected during a refuse collection may be communicated to the central server. The server is further configured to effect a datastore lookup for comparing the GPS co-ordinates of the collected refuse bins with pre-recorded geographical data of a plurality of users for associating each refuse bin to a corresponding user.
