Exploring the potential of circular economy in the food sector

The growing global demand for food has exposed the unsustainable nature of our current food system, necessitating a transition towards a more sustainable model. This sustainable system should emulate natural processes, operating in a circular manner where the output of one phase serves as the input for the next. This concept is known as the circular food economy. Innovative technologies have emerged, harnessing food by-products to create textiles, cosmetics, organic fertilizers, and biodegradable packaging. However, several obstacles, including unreliable food waste estimates, limited financial resources, inadequate technological infrastructure, and legal frameworks, hinder progress towards a circular food economy. To facilitate this shift, substantial investments are required in advanced infrastructure and technologies, promoting resource efficiency. This paper delves into the potential of a circular food economy as a viable alternative to the current linear supply chain, emphasizing the importance of closing the loop for a more sustainable and efficient food system.
