TREWITHEN Dairy and Lostwithiel Rotary Club have teamed up to turn pints of milk into pints of cash for a good cause.
The dairy has commissioned 1,200 specially designed glass milk bottles with retro labels in their Pint for Change campaign.
These will be delivered to all Rotarians from 41 clubs in Cornwall, Plymouth, west Devon and the Isles of Scilly.
The Rotarians then have four months to fill their bottles with loose change to raise as much money as possible for the End Polio Now initiative.
The bottles will be collected at the end of October to coincide with World Polio Day on October 24.
Through the End Polio Now campaign, the world has almost been freed of the potentially fatal, infectious disease.
About seven million children have been prevented from contracting polio since 1988, when 125 countries were polio endemic.
Today only three countries are still reporting cases of polio – Nigeria, Afghanistan and Pakistan.
Trewithen Dairy founder Bill Clarke, a member of Lostwithiel Rotary Club, said: "The idea behind Pint for Change was a simple one; to come up with a creative way to motivate people to raise money for a cause that is especially close to our hearts.
"We don't actually use glass milk bottles in the dairy any more but they are very striking to look at and evoke fond memories in many people, so both Trewithen Dairy and Rotary hope that people will take these bottles and fill them so that the value of the contents can be magnified across the globe."
Year 10 students at Fowey Community College helped put stickers on 500 bottles to raise £100 for their Year 11 prom.
"Rotary is working hard to raise awareness and to finally eradicate this terrible disease from the remaining endemic countries," said Rotary district governor Stephen Lay.
"We are all extremely grateful to Bill Clarke and Trewithen Dairy for supplying the milk bottles and the labels and also to Absolute and Excess Energy – Trewithen Dairy's communications agencies – for volunteering their time and resources to make this a success.
"We urge people to get behind this brilliant initiative.
"The cream on the top is that for every £1 raised, the Bill and Melinda Gates Foundation is giving Rotary another £2 to End Polio Now."
