Upcycling means converting resources, that would otherwise have been lost to human consumption, into new products of higher value. It contributes to sustainability by reducing food waste and conserving valuable resources. Breweries usually direct spent grains to farms for animal feed, biogas production or just discard them. Agrain gives them a second chance and transforms spent grains into aromatic and nutritious flours and like so, we keep valuable ingredients in the food chain without cultivating more land.
