Abstract

L'invention concerne un procédé de destruction de supports de données permettant de broyer et de détruire des supports de données à caractère confidentiel, en papier et similaire, sans possibilité d'accès aux supports de données. Lesdits supports de données à caractère confidentiel sont collectés dans des récipients collecteurs sécurisés à un point d'origine (A) et acheminés jusqu'à un dispositif de destruction (2). L'objectif de l'invention est de rendre possible la mise en œuvre de ce procédé directement au point d'origine (A) à un coût réduit, avec une efficacité accrue sur le plan énergétique et avec un faible niveau de bruit. À cet effet, après la collecte des supports de données à caractère confidentiel au point d'origine (A) dans un récipient collecteur sécurisé (1), ledit récipient est transporté jusqu'au dispositif de destruction de documents (2) qui comprend un dispositif désintégrateur (20) installé à demeure sur le lieu du point d'origine (A), puis les supports de données à caractère confidentiel sont vidés, sans possibilité d'accès, du récipient collecteur sécurisé (1) à un espace intérieur (201) du dispositif désintégrateur (20), un processus de désintégration hydromécanique des supports de données à caractère confidentiel est alors lancé après mélange avec un fluide désintégrateur et le processus est mis en œuvre au moyen d'un dispositif de brassage (202) pour former une suspension composée des documents défibrés et du fluide désintégrateur, les supports de données à caractère confidentiel étant ainsi rendus illisibles.
