Comparison of Results from Life Cycle Assessment when Using Predicted and Real-life Data for an Anaerobic Digestion Plant

Increased separation of food waste driven by the European Circular Economy Action Plan will create a need for establishing new treatment plants that can turn waste resources into high value products. This paper presents a real example of how life cycle assessment was used as decision support when es...
