British designers create non-stick chewing gum that dissolves




The Government currently spends £150 million each year removing chewing gum from the streets using chemicals.
Rev7 has the same taste and texture as normal gum, but is water soluble and can be easily removed from clothes using soap and water.

Tests showed that over 50 per cent can be removed by conventional street cleaning.
Any gum washed into the drains will degrade into minerals, biodegradable products and inert materials.
It is hoped that Rev7, designed at Bristol University in spearmint and peppermint flavours, will go on sale in the UK soon.
The gum contains a special polymer which makes it far less sticky.
Prof Terry Cosgrove said: “The motivation to invent the product came from seeing chewing gum on the streets in this country and in America. It’s everywhere.
“The materials developed can be used for lots of other uses such as anti-graffiti paint and bacterial protection.
“But because chewing gum is such an enormous problem at the moment we decided to target this as our main area.
“This is like a dream come true for me, seeing academic research result in a real commercial product.
“The team at Revolymer have done a brilliant job in making this great tasting, environmentally friendly chewing gum.
“There are also several other exciting ventures in the pipeline.”
Revolymer, a company set up by Bristol University, used a £10 million grant from investors to launch the product.
Prof Cosgrove’s team developed non-stick gum three years ago and set up the company.
Since then, they have been working on the gum’s flavour and texture at a factory in north Wales.
They made more than 1,000 pieces of gum from more than 200 different formulae to make the gum “as good a chew” as its predecessor.
A stick of gum costs around 3p – and it costs an estimated 10p to scrape it off the pavement using freezing machines, corrosive chemicals or even high-pressure steam hoses.
The product’s £10 million backer IP Group, an intellectual property firm, has acquired an 11.2 percent stake in Revolymer.
Normal chewing gum is made from synthetic latex, which is resistant to the weather and is strongly adhesive.
Over 300,000 tons of chewing gum will be sold this year in the US alone and around 120,000 tons of residual chewing gum remains in the environment every year.
Chris Tamillo, Revolymer’s Vice President of Sales and Marketing, said: “Revolymer is offering a premium product that will change the chewing gum industry significantly.
“There is both an appetite for this new brand in the US and a willingness to provide consumers with a product that is better for the environment but does not sacrifice on quality.”
Chewing gum is a problem worldwide and has even been banned in some countries.
If discovered smuggling gum into Singapore you can face one year in jail and a £10,000 Singapore dollar fine.
