As the creator of a third of the world’s greenhouse gas emissions, food production is a large contributor to the climate crisis. Yet nearly a third of that food is wasted. Toast Ale, a UK-based brewing company, is among the businesses aiming to tackle this food waste problem head on. Using surplus bread to brew beer, they hope to create a circular economy that produces tasty, sustainable beverages. Their circular economy model, which is regenerative by design, reduces the need for barley by using bread that otherwise would go to waste. This practice is designed to use less land, water, and energy, and avoid carbon emissions.
