Take a look at the essential events, concepts, terms, quotes, or phenomena every day and brush up your knowledge. Here’s your UPSC Current Affairs knowledge nugget for today on polymer banknotes (Plastic notes).The Reserve Bank of India (RBI) plans to launch polymer banknotes at the beginning of next financial year (FY28), and people will initially get hold of lower denomination “plastic” notes, that of Rs 10 and Rs 20. In this context, let’s know the objective and benefits of introducing polymer banknotes. 1. “Polymer notes have two purposes. One, it enhances the durability. This is relevant especially for the lower denominated notes with higher velocity. These notes have been in circulation for more than 30 years in various countries, and one finds that the life is much more, around 2-4 times the life of the paper currency,” Malhotra said at the central bank’s post monetary policy press conference.2. “The second purpose is to expand our capacity as the needs of the economy increase,” he said. The new notes will be checked for durability and adaptability to Indian conditions before the RBI clears it for circulation.3. The project will begin with the lower denomination notes of Rs 10 and Rs 20 which have “higher velocity” to change hands, and thus are prone to more wear and tear.4. The RBI’s trial of plastic notes will see 100 crore pieces of Rs 10 and Rs 20 notes each being introduced, totaling Rs 3,000 crore. The central bank’s subsidiary Bharatiya Reserve Bank Note Mudran Private Limited had last month floated a global tender for 3.4 crore polymer sheets for the same purpose.Where are plastic notes adopted?5. First issued by Australia in 1988, plastic banknotes are now used in more than 50 countries and are widely considered to be far superior to paper ones.Story continues below this ad The UK and Canada are among the developed countries that use polymer notes.

Thailand, Vietnam, Malaysia, and Singapore also use plastic currency, albeit not exclusively.What are the benefits of using plastic notes?7. The biggest advantage plastic notes provide over paper notes is that they are far more durable, lasting anywhere between two to six times longer depending on the denomination of the note (small denomination notes are handled more frequently, which reduces their life). And this longer life is the source of nearly all the benefits.8. One, a longer life means fewer plastic notes need to be manufactured over any period of time. Two, printing fewer notes reduces costs related to making them — even though one plastic note is more expensive to make than a paper one — distributing them and destroying them. And the elimination of these costs has a favourable impact on the environment. RBI’s cost of printing currency.9. Back in August 2013, the RBI had said it had asked The Energy and Resources Institute (TERI) to conduct a study on the carbon footprint of cotton-based currency notes and plastic ones over their entire lifetime. This ‘Life Cycle Impact Assessment’ came to the conclusion that replacing cotton-based notes with plastic ones would have “significant environmental benefits”.Story continues below this adALSO READ | Wild Buffalo in focus: Why Chhattisgarh is racing to save its state animal10. “Polymer/plastic banknotes (and the waste from production) can be granulated and recycled into useful plastic products such as compost bins, plumbing fittings and other household and industrial products. The base material of polymer is a non-renewable resource, but due to its recyclability, it has more than one life,” the RBI had said.11. There is also the security advantage. According to British firm De La Rue, which supplies notes to more than half of all central banks, plastic notes are more secure as most counterfeit notes are produced on paper. As such, counterfeit rates have fallen in countries where currency notes are made of polymer.But what’s the concern?12. Despite all the positives of plastic notes, one issue remains: the possibility that India may end up having to import the sheets that are used to print banknotes.13. While the tender expressly said bidders must ensure that their operations in Pakistan or China, if any, must be “suitably firewalled” from those in India, no raw materials be procured from these two countries, and that no employee who has previously worked or been posted or is citizen or person with origins in these countries be engaged for the India project, depending on a foreign entity for your legal tender is a vulnerability.Story continues below this ad14. Thus, any shift to plastic must be gradual for two reasons. One, considerable investment has already been made. Two, more investment will be required for the plastic transition.BEYOND THE NUGGET: What is legal tender? and where are bank notes and coins produced/minted?1.

However, such banknotes issued earlier can still be found in circulation and these banknotes continue to be legal tender.Where are bank notes and coins produced/minted?7. Bank notes are printed at four currency presses, two of which are owned by the Government of India through its Corporation, Security Printing and Minting Corporation of India Ltd.
