Spectra Systems Corp. announced Monday it has secured patents for machinery that will allow the world’s central banks to effectively clean currency
for reuse rather than paying billions of dollars each year to replace it.

actually bears some resemblance to a laundry appliance.

Annually, the world's central banks shred roughly 150,000 tons of worn-out cash — about 150 billion notes — and spend almost $10 billion
replacing the currency. Spectra also announced that it will have a machine ready for sale by March 31. The unit will clean up to 130,000 banknotes in
one run and can clean up to 150 million notes per year, according to a news release.
As people handle currency, it attracts oil from skin, or sebum. The sebum yellows the notes and built-up sebum disqualifies the money under the
standards of many central banks. It can also damage security features.
