In Canada they last 8-16 years… polymer notes are unequivocally better. Corruption and inertia is the only reason they are not everywhere. As to plastic pollution, banknotes are already a closed, circular loop and hence you get the miracle properties of plastic without the downside.

I think the concern was with the plastic money shedding micro plastics or threads as it slowly degrades over time, like we're finding other plastic does like our clothing. Not saying enough to take out of circulation, but does it shed any particles during its life?

Does it shed particles? In a world of absolutism yes they would.

I don’t know if there are actually any studies but fyi cotton notes will also have plastic features and a synthetic, uv cured varnish to try and get some extra life (although far less than polymer) so also ’shed’. Banknotes are regularly inspected and worn or damaged notes are pulled - they really are the perfect product for plastic.

Show me anyone who is actually 'concerned' about that with numbers to back up that there is any significance.
