Uncertainty analysis in the financial assessment of an integrated management system for restaurant and catering waste in Spain

Purpose The goal of this study is to analyze the economic performance of an alternative system for waste management proposed by the European Integral-b project. Its aim is to treat both used cooking oil (UCO) and solid organic waste (SOW) from the hospitality sector by biodiesel production and anaerobic digestion, respectively. A cogeneration engine adapted to use glycerol as a fuel is implemented. These results complement others from a previous life cycle assessment (LCA).
