Vegetarians outraged by Britain’s new banknote

The Bank of England in September unveiled an innovative five-pound note made of thin, flexible plastic. The idea, the bank said, was to introduce a longerlasting, waterproof currency that would be difficult to counterfeit.

But the bill bearing Sir Winston Churchill’s image also contains trace amounts of a substance that is proving to be highly controversial: animal fat.

The Bank of England confirmed Monday that its five-pound notes contain “a trace of tallow,” an animal fat product commonly used as an industrial lubricant and sometimes found in candles, soaps and other household items.

“There is a trace of tallow in the polymer pellets used in the base substrate of the polymer five-pound notes,” the bank tweeted on Monday.

The backlash was immediate: “How sick, unnecessary & prehistoric,” wrote one user.

“Not cool at all,” added another. “I go to a lot of trouble to avoid animal products. Going to start refusing them.”

A petition on the site Change.org calling on the bank to cease the use of animal products in its currency had more than 11,600 signatures as of Tuesday morning.

“When you consider that beef tallow is a co-product of a cruel and violent industry that kills millions of cows every year and that is one of the largest producers of greenhouse-gas emissions in the world, the decision to use animal fat in the new British five-pound note truly doesn’t make sense,” a spokeswoman for People for the Ethical Treatment of Animals said in an email.

The Bank of England, which has already printed 440 million new five-pound notes, has not announced plans to change the makeup of its bills. The bank is starting to phase out its use of cotton paper in currency. Plastic 10- and 20-pound notes are also planned.

Australia was the first to introduce polymer currency, in 1988. A number of countries, including Canada, Singapore, Chile and Nepal have followed suit.

In the case of the polymer notes, small beads of tallow are likely used to help the currency feed smoothly through machines, to ensure that it doesn’t jam or get stuck, said Alan Sentman, a chemist and lab manager at Polymer Solutions, a testing lab in Virginia.

But, he added, tallow isn’t exclusive to animal fat. It can also be derived from vegetable oils, cocoa butter and other non-animal sources.

“They absolutely could move to a pure vegetable alternative — there’s no reason that wouldn’t work,” Sentman said. “It’s just a little bit cheaper to do with animal fat.”

Small beads of tallow are likely used to help the new British five-pound note, above, feed smoothly through machines to ensure that it doesn’t jam or get stuck, an expert says. But vegetable products could also be used.
