Very interesting. I wonder what the USA does with worn out money? I think we pulverize and burn it, but not sure. This is a clever and useful way to dispose of excess money. And since my mulch is primarily composed of leaves, bark chips and homemade compost, it may not have been made out of money, but it's worth it's weight in gold to me. Cheryl

Only 300,000 pound per ton? I would have guessed MUCH more.

Presumably if they did it in the States it would definitely count as a 'green'.

The Royal Household uses their shredded documents for stable litter ... then composts it.
