Our completely automated, multi-level recovered paper sorting facility features a 60m long sorting line. Here, recovered paper which has been collected from domestic households is sorted according to various types. Foreign materials are identified automatically by the sorting line during the process, and removed in several stages from the material flow.
Any paper which does not conform to the pre-defined material flow (the quality standard to be achieved by the end of the sorting process) is siphoned out (negative sorting) and stored in one of several bunkers. From here, the various quality grades pass along conveyor belts to a horizontal baler.
During the multi-level sorting process, machines automatically separate large pieces of cardboard (coarse screen) from small pieces (fine screen), and graphic paper from non-graphic paper (PaperSpike). The quality of printed and coloured paper is detected via optical infrared sensors and extracted from the material flow by means of compressed air.
