Applicability of wet gasification technology for various animal and municipal wastes was examined. Wet gasification of swine manure and raw sewage sludge generated high number of net energies. Furthermore, the moisture content of these wastes is ideal for current wet gasification technology. Significant quantities of water must be added to dry feedstock wastes such as poultry litter, feedlot manures and MSW to make the feedstock pumpable. Because of their high ash contents, MSW and unpaved feedlot manure would not generate positive energy return from wet gasification. The costs of a conceptual wet gasification manure management system for a model swine farm were significantly higher than that of the anaerobic lagoon system. However, many environmental advantages of the wet gasification system were identified, which might reduce the costs significantly. Due to high sulfur content of the wastes, pretreatment to prevent the poisoning of catalysts is critically needed.
