Global demand for food is constantly increasing and it is driven by both, population growth and a rise in consumption in developing regions due to increased living standards. As the global resources are limited it requires changes in approach i.e. shift from linear to more efficient circular agri-food systems. Maximizing circularity and cascading effects between crops, livestock and food industry will help to produce animal products with fewer edible resources and less environmental impact thus maximizing the global efficiency of the food systems. To achieve this goal, non-edible biomass from the food production process can be valorized as by-products of the food-chain. Using the potential of livestock to convert inedible products/alternative feed to valuable proteins is necessary for optimal utilization of biomass components across industries.
