Is potato milk the most sustainable dairy alternative yet?

Nichola Daunton

Sales of plant-based food have increased by a huge 49% in Europe in the past two years alone, so it’s no wonder that new companies are trying to enter the market. In the UK, nearly a quarter of British people now consume plant-based milk, with that figure rising to 33% among 18-24 year olds. Suitable for vegans and nut-free, claimed as the most sustainable dairy alternative yet, Swedish company DUG has just won a 2021 World Food Innovations Award in the Best Allergy Friendly Product Category for its creation: potato milk.

Created by Professor Eva Tornberg, at Lund University, DUG is the name of the latest plant-based milk to challenge oat milk’s crown as the most sustainable plant-based milk. It is created from an emulsion of potatoes and rapeseed oil. According to DUG, potatoes are packed full of antioxidants and vitamins.

The company’s website states that growing potatoes is twice as efficient as growing oats per square metre, and potato milk has a lower carbon footprint than any other plant-based milk, clocking in at a tiny 0.27kg CO2 per litre. Potatoes are also a fairly easy crop to look after, meaning they need 56% less water than almonds to grow.
