Recovery of energy and nutrients from urban and industrial residues
Analysis of Nitrogen Flow in Food Waste: A Case Study of the University Restaurant - University of Brasilia
Short Introductive summary
This present study focused on quantifying the consumer driven nitrogen loads to the environment resulting from food waste based on Material Flow Analysis (MFA). Applying the bottom-up approach, drawing from the quantity and intensities of several types of food to estimate the nitrogen stock, we calculate the Nitrogen flows from 6 food categories (vegetables, legums, meat and eggs, bread and pasta, milk and derivatives, and fruits) based on data collected on site which considered the university restaurant weekly menu and the amount of waste generated during the cooking and consumption. Specific procedures include examining nitrogen input and output sources, intermediary processes within the university restaurant using MFA and the STAN software, identifying main flows, processes, and critical loss and waste points in food production.
