Prioritize and choose the best process of anaerobic digestion to produce energy from biomass using analytic hierarchy process (AHP)

Abstract

Using anaerobic digestion technology for the production of biogas micro and macro scales is considered as a promising approach, especially in development projects, management, and organization of organic waste generated in urban and rural areas. Conditions such as climate, culture, economy, and technology create different models of energy production systems from waste. Different devices in the world are built and operated. Choose the most suitable method for production of energy with the highest quantity and quality is the main concern of researchers and users. Analytical Hierarchy Process is a technique that is useful for decision-making on the basis of criteria considered in choosing the best system and using the views and experiences of experts in this field. In this study, three anaerobic digestion system to generate energy from biomass were compared couple based on the possibility of localized within the country, dependence on other energy sources, sensitive to the quality of input sources, allowing installation in various capacities, worldwide feedback, ease of set-up and installation and the complexity of the system. Dranco digestion system with relative value 0.471 and inconsistency rate 0.08 is an anaerobic digestion system that preferred experts to produce energy from biomasses in Iran.
