The process of production of Banknotes and security documents is highly complicated. In all steps of printing and post process, waste can’t be avoided. This waste must be securely and entirely destroyed with automated destruction solutions. The choice of the waste disposal in the field of data protection is certainly decisive, but environmental protection is getting more and more important. The separation of the different materials such as polymer, cotton or hybrids is base for an efficient recycling process. The Green-Line-Concept from Hunkeler Systeme AG saves on costs and respects the environment. The energy consumption of suction systems is significantly lowered, the waste heat supplies sufficient energy to heat the production rooms. Both existing and newly commissioned suction systems benefit greatly from the Green-Line-Concept.
