ELI5: If banknotes are manufactured daily. How are old banknotes disposed of ? How is an equilibrium maintained ?

When you buy stuff with cash, (if not you, other people do) business will end up with a lot of money at the end of each day. They take the cash and deposit it in a bank so they can pay their debts and other business stuff.

Banks will remove old or damaged bills and replace them with fresh new bills. No new money has entered the system, it's just traded out.
