Abstract
A method for the destruction of data carriers preventing access to the process of rendering confidential data carriers, which consist of paper or similar material, unreadable and allowing the carriers to be destroyed. In the method, confidential data carriers are collected at the point of origin in secure collection containers, removed by a collection vehicle, and are supplied to a paper recycling plant in a final step. The interior of a mobile pulper, which is connected to the collection vehicle, is filled with the confidential data carriers, the carriers are mixed with a pulping fluid and the mixture is blended by an agitator to form a suspension of defibrated documents and pulping fluid, a hydromechanical pulping process taking place in the pulper before the suspension is supplied to the paper recycling plant.
