Solid state anaerobic digestion as a possible solution for managing existing mechanical biological treatment plants in a more efficient way: a real case analysis
AbstractThe exploitation of Mechanical Biological Treatment is quite diffused for treating fractions of Non-Differentiated Waste. A large part of the Italian Mechanical Biological Treatment facilities operate mainly by reducing and stabilizing the Non-Differentiated Waste mass before landfilling. This way of managing Mechanical Biological Treatment can be improved by the adopting a new treatment section, based on the Solid State Anaerobic Digestion process. In this way, the Waste Organic Fraction arising from the mechanical sorting of the Non-Differentiated Waste can be treated before the aerobic stabilization section of the existing Mechanical Biological Treatment. In Italy more than 40% of the working Mechanical Biological Treatment facilities have features suitable for being upgraded with a new Solid State Anaerobic Digestion section. In these plants the amount of the rapidly biodegradable fraction is about 1,100,000 tonnes per year, leading to the production of about 300 GWh of renewable energy. The results concerning a real case study show that, with the adoption of a new Solid State Anaerobic Digestion section, about 150 kWh of electric energy would be able to be produced per each tonne of Waste Organic Fraction. Furthermore, there would be a significant reduction in the Organic Load Rate [kgVS/m3*day] for the existing aerobic section of the plant, leading to additional savings of 160-320 kWh per day, depending on the amount of Waste Organic Fraction diverted from the Solid State Anaerobic Digestion. Results from the economic analysis show that the Solid State Anaerobic Digestion treatment cost ranges from about 6 up to 23 € per each tonne of Non-Differentiated Waste entering the existing Mechanical Biological Treatment plant.
