Sustainable Upcycling –
The Power of Circularity

What we do

Reintroducing barley to the food industry

Our innovative solution transforms side streams of the brewing industry into valuable raw materials to supply the ever-growing demand for healthy and sustainable plant-based alternatives.

In other words, we save barley grains from the brewing process to produce protein and fiber products for a wide variety of applications in the food industry. This promotes the transition towards a sustainable and circular food economy.


Balance through resource efficiency

At Sustainable Ingredients, we strive for a world in which food waste and pollution is minimized. Our upcycling technology enables us to produce with a 60% lower environmental impact than conventional alternatives such as soy or pea protein.

Our unique mechanical separation and drying process handles the barley with care to extract all valuable properties. Our gentle, efficient, and eco-friendly methods valorize residuals into usable goods at an unparalleled standard.
