The Sustainability of Oat Milk
December 9, 2020
It should come as no surprise that as a society we need to reduce our environmental footprint. One way you can do this is by incorporating sustainable foods into your diet. A wave of information shows that cow’s milk is very resource depleting and produces a lot of greenhouse gases. Swapping dairy for more sustainable products means consumers are now facing the challenging decision of choosing between all of the alternative milk options. Fortunately, research is pointing to a new, tasty and sustainable alternative to milk… oat milk!
One of the most impressive ways that oat milk is sustainable is in its water usage. Only 48 liters of water are needed to produce 1 litre of oat milk, compared to almond milk which needs 371 litres of water to produce 1 litre of milk. That’s 6x less water to produce the same amount of milk! This difference is extremely significant and emphasizes the sustainability of oats and oat milk products. In addition, because Canada is the number one producer of oats in the world, oats can often be sourced locally, reducing the greenhouse gas emissions required by transportation.
Another interesting fact about oats that contributes to its sustainability is that the by-products of production can be used as a source of energy! Oat husks left over after production can replace coal to generate electricity and steam, and the oat husks are also used in animal feed and animal bedding. As an environmentally conscious consumer, it is reassuring to know that the products you buy use sustainable production practices that limit energy consumption and reduce waste.
