South Island company Spout is helping to reduce the number of plastic milk bottles by offering a milk-in-keg service to big milk consumers.
It found a natural client base in restaurants and cafes - but now has a number of bigger companies on board with lots of employees who guzzle through the milk in the work kitchen.
The kegs are reused after cleaning, and the company says its 'farm to flat white' model is zero waste and supports local farmers.
One of the company's co-founders, Nick Jackson, joins Kathryn to explain how it works and plans for expansion.
