The Pros and Cons of Polymer

Polymer bills are cleaner and more hygienic than paper and cotton-based notes. They are more durable, too, and last longer in circulation (about five years for a plastic note as opposed to the approximately two-year lifespan of a paper bill). In addition, certain security features aren't possible without the use of a polymer substrate. All of these differences add up to direct and indirect savings for the economy, making plastic notes an attractive proposition for monetary authorities around the world.

Of course, there are trade-offs. Plastic banknotes can shrink or melt when exposed to temperatures above 120 degrees Celsius (248 degrees Fahrenheit), and the notes do sometimes stick together thanks to static electricity. This last problem is a serious issue, since businesses and consumers may inadvertently lose money when paying for purchases or giving change.

This is why anti-static measures--such as the controversial use of tallow--are taken in the first place.

But is there an acceptable alternative?

The key ingredient in tallow is stearic acid, a common natural fatty acid. It is found most in the adipose tissue of animals, but it is also found in coconuts and the nut of the shea tree. The only issue is whether it can be extracted from such vegetable sources in quantities great enough and at costs low enough to match the scale of polymer banknote production.

As it is, the Bank of England has no firm plans to eliminate the use of tallow from its banknote production process, though the Bank does say that it is working on the matter. Unfortunately, it appears that any changes to the supply chain will not take place in time to prevent either the upcoming polymer £10 and £20 notes from containing animal fat. The new £10 note will feature Jane Austen on the front and is set for release in 2017; the new £20 note, featuring the prescient English painter J. M. W. Turner, is scheduled for release in 2020.

Even petition creator Doug Maw is pragmatic about what the Bank can and cannot do. While he is hopeful that all animal products will be removed from future bills, he doesn't expect anything to happen to the notes already in circulation.

The Reserve Bank of Australia has been forthright about the animal content in its banknotes, as has the Bank of Canada. In contrast, the Reserve Bank of New Zealand has made no comment, instead referring all inquiries to Innovia.

Amanda Sorrenson of the Vegan Society of New Zealand said that the reality of animal-based products in the nation's cash supply was an unpleasant discovery. "What, are vegans going to use coins?" she said. "I don't think it particularly pleases anybody to know that there's animal fat in your wallet."

She also said that the issue didn't rise to the level of protest on the Vegan Society's part.

"You've got to put up a guard about achieving perfection... You can't bend over backwards and become a very strange person in your endeavor."

At any rate, different people have different takes on the situation.

Simon Round, a spokesman for the Board of Deputies of British Jews, told the British Broadcasting Corporation (BBC) that "Jews are not allowed to consume tallow but are permitted to handle it."

Mike Rigby, a member of the Manchester Vegan and Vegetarian Group, claims that he had broached the same question as Steffi Rox, only six weeks earlier.

"Given the years of consultation, research and development that went into this, I'm amazed that no affected groups, such as muslims or vegans, have piped up until now, when it's far too late to do anything about it," Rigby said. "Even if they switched the production tomorrow we'd be in the ridiculous situation of looking for certain 'safe' serial numbers to see which we were 'allowed'."

NEW POLYMER NOTES CONTAIN ANIMAL FAT(www.coinbooks.org/esylum_v19n49a29.html)

Here's another article, this time from India, forwarded by Kavan Ratnatunga, who writes:

Hindu temples have banned the new five pound note after it was revealed that it contained animal fat.

The Bhaktivedanta Manor, a Hare Krishna temple in Hertfordshire, posted a photo of a sign to Facebook which said: "We no longer accept the new five pound notes as they contain animal fat. Apologies for the inconvenience."

The National Council of Hindu Temples has issued a statement against the new material and said the money "ceases to be a simple medium of exchange but becomes a medium for communicating pain and suffering and we would not want to come into contact with it."

The statement continued: "We are very comfortable that this has happened without any malicious intent but merely out of ignorance and a lack of sensitivity and knowledge and it seems that steps are being taken to ensure that this error is corrected.
