Countries are switching to polymer notes to save the environment
For countries concerned about the environmental impact of the currency, a switch to polymer notes makes sense
As countries sign on to the Paris Agreement on climate change and strive to become more sustainable, many are considering the environmental impact of their currency as well as its durability and security.
Money has been made from a variety of materials over the years—from leather in China during the Han Dynasty, to shells, precious metals, cotton paper, and most recently, plastic. The materials reflect the social and political climate of the time as well as available technologies and resources.
A brief history of notes
For centuries, people in China used precious metal coins strung together through a center hole to conduct transactions. But with larger commercial transactions in the 7th century, there was a move to the easier-to-transport paper currency.
In the 13th century, Marco Polo reported back to Europe from his travels on the use of paper rather than coins, and Europe’s earliest modern paper banknotes were issued by the Bank of Stockholm in 1661.
Paper quickly became the currency of choice around the world and remained so for centuries. But with recent technological developments, plastic film notes offer additional security features along with longevity and energy efficiency.
Let”s move to plastic
Polymer banknotes were first issued in 1988 by Australia, which now uses polymer exclusively and has lauched back in 2016 its new series of notes. Polymer is now used in over 20 countries as diverse as Australia, Canada, Fiji, Mauritius, New Zealand, Papua New Guinea, Romania, and Vietnam.
The Bank of Canada began its move to polymer banknotes in 2011, after assessing the environmental impact of producing paper and plastic bills. A life-cycle assessment examined the effect—including primary energy demands and the potential for global warming—of each stage of production, from growing the cotton to produce the banknote paper or producing the raw material for polymer notes through the destruction and disposal of worn notes.
Polymer outperformed paper
In all categories and phases, polymer outperformed paper. For example, the study found, a polymer bill promises a 32 percent reduction in global warming potential and 30 percent reduction in primary energy demand compared with paper.
Most important, polymer notes last more than twice as long as paper notes—and higher denominations, which are handled less frequently, last even longer. This means fewer polymer notes have to be manufactured and distributed over the life of a series. And polymer notes weigh less than paper ones, so even their transportation and distribution are easier on the environment.
At the end of their life, paper bills are usually shredded and relegated to a landfill. But polymer notes taken out of circulation are shredded, converted into pellets, and used to make everyday plastic items such as lawn furniture.
The Bank of England spent three years studying the potential effect of a switch from cotton and linen paper notes and concluded as well that plastic was the way to go. A polymer £5 note featuring Sir Winston Churchill will launch in September 2016, followed by a £10 Jane Austen note in late 2017 and a £20 note by 2020.
The quality of polymer notes is higher, they are more secure from counterfeiting, and they can be produced at lower cost to the taxpayer and the environment.
Ordinary users have mixed reactions to the bills’ plasticky feel. They don’t fold up nicely like paper bills when they’re new, and they’re slippery, which might end up they slide out of the pocket, say some. On the other side, .they’re so much cleaner and the fact that they’re waterproof means getting them wet isn’t going to cost you.
