The assessment involved employing analytical tools such as life cycle assessment and mass flow analysis to gain a comprehensive understanding of the meat supply chain. A decision-support framework was developed to guide the optimal and most environmentally beneficial utilization of animal by-products.

The new research findings provide valuable insights into the strategic management of animal by-products. They demonstrate how such management can bring environmental and food security benefits, ultimately contributing to a more sustainable development of the meat industry.

The PhD study was completed at Department of Agroecology, Faculty of Technical Sciences, Aarhus University.

This summary was prepared by the PhD student.
