Method for the destruction of data carriers, collection vehicle and use of a pulper

A vehicle for collection and hydromechanical disintegration of confidential data carriers, which are in the form of paper and collected in security collection containers at a location of origin, and for transportation of the confidential data carriers from the location of origin to a paper recycling facility, said vehicle comprising:

• a mobile disintegration device having an interior, the mobile disintegration device being installed on the vehicle in a fixed manner or being fastened on a trailer of the vehicle;
• a loading device coupled to the mobile disintegration device, the loading device transferring the confidential data carriers from the security collection containers, which are sealed and secured so as to prevent access at the location of origin to the confidential data carriers, into the interior of the mobile disintegration device at the location of origin in a manner which is secure and inaccessible to unauthorised persons;
• and
• a circulation device in the interior of the mobile disintegration device, the circulation device, during transport of the confidential data carriers from the location of origin to the paper recycling facility, mixing the confidential data carriers in the interior of the mobile disintegration device with a disintegration fluid so as to produce a suspension of defibrated documents and disintegration fluid through a hydromechanical disintegration of the confidential data carriers, the circulation device disintegrating the confidential data carriers into fibers during transport so as to render the confidential data carriers unreadable and therefore destroyed.

A mobile disintegration device for hydromechanical disintegration of confidential data carriers, which are in the form of paper, during transportation of the confidential data carriers from a location of origin to a paper recycling facility, the mobile disintegration device being carried along with a collection vehicle, said mobile disintegration device comprising:

• an interior;
• a loading device transferring the confidential data carriers from security collection containers, which are sealed and secured so as to prevent access at the location of origin to the confidential data carriers, into the interior of the mobile disintegration device at the location of origin in a manner which is secure and inaccessible to unauthorised persons;
• a disintegration fluid mixed with the confidential data carriers in the interior of the mobile disintegration device;
• a circulation device in the interior of the mobile disintegration device, the circulation device, during transport of the confidential data carriers from the location of origin to the paper recycling facility, mixing the confidential data carriers in the interior of the mobile disintegration device with the disintegration fluid so as to produce a suspension of defibrated documents and disintegration fluid through a hydromechanical disintegration of the confidential data carriers, the circulation device disintegrating the confidential data carriers into fibers during transport so as to render the confidential data carriers unreadable and therefore destroyed;
• and
• a dewatering device separating part of the disintegration fluid out of the suspension so as to increase the density of the suspension after the confidential data carriers have been disintegrated into fibers.
