One of the main most visual environmental impacts of banknotes is not in their production but their destruction – with incineration and landfill still being all-too-frequent methods of removal. In last month’s Currency News™, we reported on the results of the 2025 Banknote Recycling Study, the latest biennial survey from Royal Dutch Kusters Engineering (Kusters), which explored how central banks are handling the disposal of unfit notes in particular, and progress made (or not) since the previous survey of 2023.

The readers of this article are likely to agree that cash, whether banknotes or coins, is a wonderful thing. Although the siren call of convenience is luring people to digital alternatives, cash remains part of the fabric of our societal DNA.
