Abstract:
... Increasing nutrient circularity and use efficiency is a leading topic in the search for more sustainable agri-food-waste systems (AFWS). This paper proposes a method to assess the role of crops and livestock in nutrient circularity and use efficiency in an AFWS. The method is based on the analysis of nutrient flows, a detailed typology of flows, and a set of 3 groups of indicators to characterize ...
