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