In the center of large sorting plants is an fully automated sorting system. In a multi-stage process, the mixed fractions are largely automatically divided into the individual substances. The result is a pure waste paper faction, which can be recycled in paper production. Where huge quantities of waste arise – if in production, trade or administration – compaction is an important part of the disposal logistic. Compacted and pure waste is secondary raw material, it simplifies the handling, allows an interim storage and reduces stock and transport costs as well as personal costs.
