A Barry milkman says sales of bottled milk are booming as consumers look for alternatives to plastic containers.
Gareth Jones of Jones Dairies says he's been distributing 2,000 more glass bottles a week since the start of the year.
Milk bottles can be re-used up to 30 times before being recycled and many milk floats are run on electricity.
Thirty years ago the traditional milkman was in his heyday but the industry has since been in decline.
But milkmen say they have been leading the way on sustainability for decades.
