Abstract

Anaerobic digestion is a key process for sustainable organic waste management. It contributes to renewable energy production, greenhouse gas emissionmitigation and to the decrease of pollutant organicmatter load. Agrifood industry is one of themain sectors producing organic waste. During 2008,
approximately 1,281,500 tons of biodegradable organic waste were produced in Catalonia, which could have been transformed to biogas through anaerobic digestion. In the present study, the energy potential of this waste has been evaluated considering its characteristics, alternative treatment and amounts produced.Uncertainty has been also evaluated by taking into account variations in composition and biodegradability. The present study shows that the energy potential of the available organic industrial waste is 118,069 toe/year,with an uncertainty percentage of 33.2 %. If only themost accessible waste is considered, the energy potential obtained is 24,600 toe/year,with an uncertainty percentage of 32.4 %, and 11,994 toe/year belonging to the agri-food industry,with an uncertainty of 34.6 %.
