This paper assesses the feasibility of producing fuel energy from sewage sludge via four processes: microwave-induced pyrolysis/gasification and conventional pyrolysis/gasification. Both pyrolysis and gasification produced gas, char, and tar. The gas produced for the gasification contained mainly hydrogen and carbon monoxide with a small amount of methane and hydrocarbons (C2H4, C2H6, C3H8). However, the gasification produced higher carbon monoxide instead of the hydrogen. The microwave gasification generated higher heavy tar compared to other processes. As a light tar, benzene generated higher value for both the pyrolysis and gasification. The sludge char showed a vitreous-like texture for the microwave process and a deep crack shape for the conventional heating process. These results indicate that the gas produced from the microwave processes of wet sewage sludge might be usable as a fuel energy source, but this would require removal of the condensable PAH tars. The sludge char produced could also be used as a solid fuel or adsorbent.
