Paper Title
Phased Anaerobic Digestion of Organic Fraction of Municipal Solid Waste

The demand for energy and industrial materials are on a significant rise parallel to the rapid industrialization and population growth in many developing countries. Therefore, alternative energy sources need to be investigated. Municipal solid waste (MSW), with its significant organic fraction (30-50%), can be an alternative energy source for power generation by biomethanation process. This work investigated the applicability of phased anaerobic digestion (AD) for the enhancement of the gas production from organic fraction of municipal solid waste (OFMSW). The experimental results indicated that up to 25%, 10% and 23% increases in biogas production, tCOD and VS removals were achieved, respectively, by phase separation. The acetic and propionic acids were not detected in the reactors which was an indication of successful methanization.
