Tesco is the first supermarket to sell water in cans rather than plastic bottles.
The retailer is now offering spring water in 500ml aluminium cans at its 700 stores under the CanO Water brand, which started two years ago in London.
“Aluminium cans have the highest recycling rate of any product out there and a recycled can could be back on the shelf as another one in just 60 days,” says CanO Water co-founder Ariel Booker.
He hopes that his cans will rival industry giants, while their minimal design and cult social media following will attract a younger generation.
