- Until now the worn and torn currency notes which could no more be circulated used to be burnt by Reserve Bank of India.
- As a result of this, the smoke polluted the environment.
- In order to get rid of this smoke problem, the Reserve Bank introduced a new policy.
- Under it a machine costing Rs. 9 crore was imported which could cut the currency notes and make their spring roles and further give them the shape of thick bricks.
- These bricks can be used for several purposes.
- In India about 5 million notes are driven out of circulation every year and they weigh about 4500 tonnes.
