Now that the exchange of money at the bank has ended the big question that arises is what happens to the old 500 and 1,000 rupee notes which were banned by Prime Minister Narendra Modi earlier this month to combat corruption and black money. The demonetisation exercise brought 18 billion 500 and 1,000 rupee notes valued at Rs. 14 lakh crore out of circulation. According to government sources the demonetised notes will be sent to Reserve Bank of India (RBI) so that it can be shred and pulped for recycling. The stack of paper that will sent to RBI will be then turned in to short strips and  after recycling it will be created into compressed blocks will be used to make office stationary. This method which is being used is completely a new method, earlier till 2001 old and discarded notes were destroyed by burning them. According to reports, the Reserve Bank of India will take over a year to destroy the recently demonetised notes. The sorting, verification and shredding of the notes is already underway at three centres in the state - Fort, in Mumbai,Belapur and Nagpur.
