In the first part of the study, Gaz de France (GdF) and the French Environment Energy Mangement Agency (ADEME) wished to identify the best method to use the biogas from anaerobic digestion of separately collected biodegradable waste (biowaste). Secondly, GdF & ADEME wished to evaluate the strength and weaknesses of the two main different organic recycling: anaerobic digestion (methanisation) and composting. In this study, two questions were treated:
- Which is the best valorisation method for biogas produced from the anaerobic digestion of separately collected biodegradable waste : fuel, heat or electricity? ('Biogas' question);
- Which is the best treatment for the separately collected biodegradable waste: anaerobic digestion (methanisation) or industrial composting? ('Composting' question).
