An electronic blocking list management system for checking authorisation to use a rubbish receptacle (2.1, 2.2, 2.n), wherein the blocking list management system comprises a data management system and multiple access systems (3.1, 3.2, 3.n), which can be activated by means of multiple keys, which are each assigned to a user or a group of users, for electronically checking authorisation to use an individual rubbish receptacle (2.1, 2.2, 2.n) associated with any individual access system (3.1, 3.2, 3.n), wherein both the data management system and each of the access systems (3.1, 3.2, 3.n) have a communication interface (10.1, 10.2, 10.n), by means of which data can be exchanged between the data management system and each individual access system (3.1, 3.2, 3.n), wherein each access system (3.1, 3.2, 3.n) has a memory device (8.1, 8.2, 8.n) for creating and storing a list of the keys (6, 6.1, 6.2, 6.n) used in a defined period of time at this access system (3.1, 3.2, 3.n) and means for transmitting this list by means of the communication interface (10.1, 10.2, 10.n) to the data management system, and the data management system has devices for creating a blocking list for the access system (3.1, 3.2, 3.n) of a rubbish receptacle (2.1, 2.2, 2.n), wherein - the data management system is configured to access a prioritisation algorithm for prioritising entries in the blocking list when creating the blocking list, wherein the prioritisation algorithm at least also takes into consideration the feature of the last use of a key (6, 6.1, 6.2, 6.n) not authorised for access at the access system (3.1, 3.2, 3.n) of the respective rubbish receptacle (2.1, 2.2, 2.n) to create, by means of the data management system, respectively, an individual prioritisation hierarchy for all keys (6, 6.1, 6.2, 6.n) not authorised for access for the access system (3.1, 3.2, 3.n) of each individual defined rubbish receptacle (2.1, 2.2, 2.n), wherein, by means of the data management system, the keys (6, 6.1, 6.2, 6.n) not authorised for access, starting with the key (6, 6.1, 6.2, 6.n) with the highest prioritisation in descending hierarchy of the prioritisation, in the individual blocking list of the access system (3.1, 3.2, 3.n) of each individual defined rubbish receptacle (2.1, 2.2, 2.n) are included until the maximum number of blocking list entries is reached, - each access system (3.1, 3.2, 3.n) has a memory device (8.1, 8.2, 8.n) for storing the blocking list created by the data management system and transmitted therefrom to the respective access system (3.1, 3.2, 3.n) for the rubbish receptacle (2.1, 2.2, 2.n) associated with this access system (3.1, 3.2, 3.n), and each access system (3.1, 3.2, 3.n) comprises a data processing device (7.1, 7.2, 7.n) and a control device (9.1, 9.2, 9.n) for granting or refusing access to the rubbish receptacle (2.1, 2.2, 2.n) associated with the access system (3.1, 3.2, 3.n) for a user associated with the key (6, 6.1, 6.2, 6.n), wherein access refusal results from a successful comparison of the key (6, 6.1, 6.2, 6.n) with the entries contained in the individual blocking list of the access system (3.1, 3.2, 3.n) of this defined rubbish receptacle (2.1, 2.2, 2.n). - the data management system is configured to access a prioritisation algorithm for prioritising entries in the blocking list when creating the blocking list, wherein the prioritisation algorithm at least also takes into consideration the feature of the last use of a key (6, 6.1, 6.2, 6.n) not authorised for access at the access system (3.1, 3.2, 3.n) of the respective rubbish receptacle (2.1, 2.2, 2.n) to create, by means of the data management system, respectively, an individual prioritisation hierarchy for all keys (6, 6.1, 6.2, 6.n) not authorised for access for the access system (3.1, 3.2, 3.n) of each individual defined rubbish receptacle (2.1, 2.2, 2.n), wherein, by means of the data management system, the keys (6, 6.1, 6.2, 6.n) not authorised for access, starting with the key (6, 6.1, 6.2, 6.n) with the highest prioritisation in descending hierarchy of the prioritisation, in the individual blocking list of the access system (3.1, 3.2, 3.n) of each individual defined rubbish receptacle (2.1, 2.2, 2.n) are included until the maximum number of blocking list entries is reached, - each access system (3.1, 3.2, 3.n) has a memory device (8.1, 8.2, 8.n) for storing the blocking list created by the data management system and transmitted therefrom to the respective access system (3.1, 3.2, 3.n) for the rubbish receptacle (2.1, 2.2, 2.n) associated with this access system (3.1, 3.2, 3.n), and each access system (3.1, 3.2, 3.n) comprises a data processing device (7.1, 7.2, 7.n) and a control device (9.1, 9.2, 9.n) for granting or refusing access to the rubbish receptacle (2.1, 2.2, 2.n) associated with the access system (3.1, 3.2, 3.n) for a user associated with the key (6, 6.1, 6.2, 6.n), wherein access refusal results from a successful comparison of the key (6, 6.1, 6.2, 6.n) with the entries contained in the individual blocking list of the access system (3.1, 3.2, 3.n) of this defined rubbish receptacle (2.1, 2.2, 2.n).
