Mixed banknote substrate circulation requires a special shredding and destruction process to enable sustainable recycling of the shreds.

Hunkeler Systeme has developed a “cotton / polymer separation system” which handle shredded cotton / polymer notes at the same time with an automated change over feature. This separation system can be connected either to an online and/or offline processing / shredding module. The challenge of mix substrates running in a parallel production is addressed.

Sustainable solutions requesting the destructed material to be presented “fit for recycling”. This allows the recycler to have an efficient recycling process that results in cost savings and increased sustainability.
