What happens to the silver strip when 40bn of notes are composted?

Around two billion paper notes will be withdrawn and recycled to be used as a soil improver for agriculture.
Beyond the silver, It's anyone's guess what potential cancer causing chemicals will enter the food chain when this happens.
What about the immense amount if ink that must have been used to originally print the notes?

I think the only time I use cash is my hairdresser.
Mind you, the credit cards aren't giving much back nowadays. I never have one which doesn't give something back.
Anyway, if we worried about every single thing that happens, or might happen, we'd never leave the house. Best stay wrapped up in cotton wool and live in a cupboard.
