Banknote - Destruction

Destruction

Banknotes last on an average of three years until they are no longer fit for circulation, after which they are collected for destruction, usually recycling or shredding. A banknote is removed from the money supply by banks or other financial institutions because of everyday wear and tear from its handling. Banknote bundles are passed through a sorting machine that determines whether a particular note needs to be shredded, or are removed from the supply chain by a human inspector if they are deemed unfit for continued use – for example, if they are mutilated or torn. Counterfeit banknotes are destroyed unless they are needed for evidentiary or forensic purposes.

Contaminated banknotes are also decommissioned. A Canadian government report indicates:

Types of contaminants include: notes found on a corpse, stagnant water, contaminated by human or animal body fluids such as urine, feces, vomit, infectious blood, fine hazardous powders from detonated explosives, dye pack and/or drugs...

These are removed from circulation primarily to prevent the spread of diseases.

When taken out of circulation, Australian bank notes are melted down and mixed together to form plastic garbage bins.
