Updated hierarchy for food surplus and waste proposed herein building on terminology from major European and national projects *FFV fresh fruits and vegetables. More in Teigiserova, D.A., Hamelin, L., Thomsen, M., 2020. Towards transparent valorization of food surplus, waste and loss: Clarifying definitions, food waste hierarchy, and role in the circular economy. Sci. Total Environ. 706, 136033. https://doi.org/10.1016/J.SCITOTENV.2019.136033. This hierarchy was recently integrated into a recent report by the European Commission’s Knowledge Center for Bioeconomy (see: Sanchez, J., Commission, E., Caldeira, C., Laurentiis, V. De, Commission, E., Sala, S., Commission, E., 2020. Brief on food waste in the European Union).

During her PhD studies, Dominika Alexa Teigiserova researched the problem of food waste in the circular economy. Food waste can be used to extract high-value products from acids to colorants, but sustainable valorization needs to be ensured. Dominika Alexa Teigiserova studied the connection to reach sustainability in current frameworks, technology, environmental performance, and governance. The research provides updated frameworks for waste hierarchy, circular economy and identifies key food waste types, technologies, and governance interventions.

The new research findings contribute to the understanding of how food waste can be used to create a sustainable circular bioeconomy.

The PhD study was completed at the Department of Environmental Science, Faculty of Technical Sciences, Aarhus University.

This summary was prepared by the PhD student.
